(B) FACTUAL BACKGROUND [13] The pertinent facts of the case as unfolded the prosecution narrative set out hereinafter are by and large reproduced from the facts as laid out quite comprehensively by the learned High Court judge ("HCJ") in the grounds of decision with necessary modifications. [14] Although they are fairly lengthy and includes matters raised in evidence, at times verbatim by certain key witnesses, it is necessary to set them out in order to place matters in perspective and to appreciate the manner in which the learned HCJ dealt with the offences and his eventual findings. [15] Zuraidah binti Mat Ali (SP17) was the mother of the three deceased children as well as SP21. She is also the wife of Mohd Fadzil Bin Mohammad (SP19). SP19 is also known as "Zam". The Appellant is also known as "Rambo". [16] The house known as "Rumah Projek Bantuan Bina Rumah Majlis Agama Islam dan Adat Melayu Perak" mentioned in the charges under section 302 Penal Code is the house in which SP17, SP19, the three deceased children and SP21 stayed as a family together with the mother of SP17 who had since passed away due to reasons unconnected with the case. [17] SP21 was 11 years old at the time of giving evidence. Before SP21 gave evidence the learned Deputy Public Prosecutor ("DPP") applied for a screen to be placed between SP21 and the Appellant and for an adult to accompany SP21 while SP21 testified. [18] The High Court Judge ("HCJ") allowed the DPP's application for a screen to be placed between her and the Appellant in accordance with section 3 of the Evidence of Child Act 2007. [19] Pursuant to section 9 of the Act, the HCJ also allowed SP21 to be accompanied by an adult, in this case SP6, her headmistress, while giving evidence. [20] The HCJ was satisfied from the explanation given by the learned DPP that SP21 was afraid to be in the presence of the Appellant and required some form of reassurance to calm her emotions when giving evidence. [21] The HCJ observed that SP21 was even afraid to enter the court for identification purposes when she saw the Appellant in the dock. [22] SP21 testified that the three deceased were her siblings and that she was the eldest. They all stayed at the house with her father SP19 mother SP17 and grandmother. [23] SP21 attended the Sekolah Kebangsaaan Sungai Haji Muhammad Selekoh, Perak (the school). SP21 's school hours are from 7am to 2pm. The school was about 60 meters from the house. [24] According to SP17, the distance between the school and SP21's house was such that the voice of the teacher teaching and the children singing could be heard coming from the school. [25] On 17.5.2018, SP21 returned home from school. She had a bath and then left the house for her religious class. She then went out to meet her friends at a small open air pondok the kampong folks called "Jumbo" in front of the school while waiting for the religious class to start. [26] At about 2.15pm as SP21 was chatting with SP20 and other friends at the Jumbo she noticed the Appellant had come to the Jumbo with a yellow and grey RXZ motor cycle. [27] She recognized the motor cycle as belonging to the Appellant who was a friend of her father, SP19. The Appellant is known to her by the name "Achik". She had seen "Achik" ride the same motor cycle on previous occasions. [28] In recalling what had happened at the Jumbo she said that when the Appellant arrived he took out a parang from its sheath and began to hit her with the parang. He had approached her from the back. She saw him when she turned her head. He hit her at the left side of her head with the parang. [29] The Appellant was shouting at that time but she could not make out what he was shouting. She did not know what had happened to the others at the Jumbo as she ran away on being struck by the Appellant. She ran to the nearby house of one Husni Mubarak (SP24) to seek safety there. [30] SP20 was 12 years old at the time of giving evidence. Upon the application of the DPP, the HCJ also allowed a screen to be placed between SP20 and the Appellant in accordance with section 3 of the Evidence of Child Act 2007and pursuant to section 9 of the said Act. [31] The HCJ also allowed SP20 to be accompanied by an adult while giving evidence, in this case her own mother. The HCJ agreed with the DPP's explanation that SP20 was apprehensive in giving evidence in the presence of the Appellant and that her mother was needed to allay SP20's fears. [32] SP20 testified that while they were at the Jumbo she suddenly heard the Appellant shouting. She thought it was a mad person. She said the Appellant attacked SP21 first. [33] He then attacked SP20. SP20 received injuries at her left arm and head. She felt that the Appellant attacked them with a parang but did not actually see the parang as the whole incident happened quickly. [34] She and SP21 then ran their separate ways. She identified the Appellant as the person who attacked her and SP20. She had seen the Appellant prior to this incident when the Appellant went to the school to give SP21 some money. [35] After having been injured, SP20 ran for safety to the house of Norazwa Binti Mohd. Sidek (SP22). SP22's house was about 35 feet away from the school. [36] Once in SP22's house, SP22 noticed that SP20's hand was bleeding. SP22 was told that the Appellant had run amok. [37] SP22 had known the Appellant for some time. He had done work for her in her late husband's oil palm estate and had once even helped her deliver a motor cycle to her son in Penang. [38] In seeing that a pupil of the school had been injured in such circumstances, SP22 tried to call Rashidah Binti Ismail (SP6) who was the head mistress of the school, but the call could not go through. [39] SP22 had to shout from her house to the security guard at the school, Noorhamizatul Fazlina Binti Tarmizi (SP25) to inform SP6 of the incident at the Jumbo and to close the school gate. [40] This message was duly conveyed and complied with by SP25.On receiving the news that her pupils had been injured, SP6 made a call to the Balai Polis Rungkup at about 2.30pm asking for help. She spoke to Lans Koperal Mohd Fazli bin Abdullah (SP14). [41] SP6 then decided to drive to the Klinik Kesihatan where SP20 and SP21 were being treated. [42] On reaching her car which was parked near the house where SP21 and her family stayed she heard screams from the house and SP19 calling her for help and his children crying. [43] SP6 also saw the Appellant in front of SP21 's house with a parang in his hand and shouting. As she was passing the house with her car a little while later the house was quiet. She recognized the Appellant as he was doing some work near the school the previous day. [44] A little earlier on, as SP25 was closing the school gate she saw the Appellant looking at her from the Jumbo. The Appellant was holding a parang. [45] The Appellant then left the place on a motorcycle. Suddenly she heard children shouting and crying. After about five minutes the shouting stopped. She wondered why the shouting and crying stopped so suddenly. [46] About 10 minutes later she (SP25) saw the Appellant again in front of the school. This time his clothes and parang were bloodstained. She heard the Appellant say he had killed three persons. The relevant part of her evidence is as follows: "TPR: Lepas Puan dengar Puan Azwa jerit, Puan kunci pintu, lepas itu ada kejadian apa lagi yang berlaku? SP25: Rambo mengangkat motor dia pergi ke hadapan. MAH Angkat apa? SP25 Angkat motor dia start ke hadapan saya tidak pasti ke mana. Tiba-tiba saya terdengar satu suara budak-budak menjerit sambil menangis, bercampur menangis, dalam lebih kurang 5 minit kemudian senyap. Bila senyap saya tertanya-tanya tiba-tiba boleh senyap, kenapa boleh senyap. Rambo tidak lama lepas itu dia pergi berlegar balik ke hadapan sekolah dengan parang baju berdarah dia sebut "aku sudah bunuh 3 orang". TPR: Dia sebut dekat siapa? SP25: Dia sebut dekat berhadapan sekolah tapi saya dengar "aku sudah bunuh 3 orang". [47] As to what happened in that approximately ten minutes when SP25 first saw the Appellant and the second time when she heard him say "aku sudah bunuh 3 orang" can be gathered from the evidence of SP22. [48] From the window of her house SP22 could observe the Appellant at the Jumbo, then she saw him move away from the Jumbo by motorcycle and saw that the Appellant was heading towards SP21's house which was about 60 meters away from her house. [49] The sound of the Appellant's motorcycle which was recognized by the loud exhaust also came from the direction of SP21's house. On seeing that the Appellant was no longer at the Jumbo, SP22 seized the opportunity and brought SP20 to the house of SP24. From there SP20 together with SP21 were brought to the Klinik Kesihatan Selekoh by SP24 for medical treatment. [50] SP21's house was situated to the right of SP7's house. The distance between the houses was only about 30 to 40 feet. From her window she saw the Appellant whom she knew as "Yang" outside the house. She described the situation as follows: "Dia mengamuk macam-macam, maki". [51] She also heard children crying inside the house and SP17 calling out "abang abang" From her kitchen window SP7 asked the Appellant: Yang, apa pasal kau ini Yang, buat macam ini, bulan puasa, kau mengucap. [52] The Appellant showed SP7 the parang in his hand in a threatening manner. This frightened SP7. The following is her account of what she saw and heard: TPR: Berapa lama Andak dia mengamuk-mengamuk di luar sebelum dia boleh masuk yang Andak dengar bunyi itu, lebih kurang? SP7: Lama juga. TPR: Andak dengar dia cakap apa? SP7: Dia cakap macam-macam. TPR: Apa dia cakap, Andak beritahu Hakim. Kan Andak kata lama juga dia mengamuk-mengamuk dia kata apa yang Andak boleh ingat? SP7: Cakap Babi, Bangsa tidak elok, macam-macam dia cakap. TPR: Babi, Bangsa tidak elok? SP7: Haa. TPR: Ada dia panggil sesiapa? SP7: Tiada. TPR: Dia tunjuk parang dekat Andak? SP7: Hmm. TPR: Masa itu Andak cakap dengan dia dari mana? SP7: Dari tingkap rumah Andak, rumah dapur. TPR: Masa dia tunjuk parang dekat Andak, dia kata apa dekat Andak? SP7: "Ini nak" katanya. Macam itu katanya. TPR: Dia tanya Andak? SP7: Haa. Lepas itu Andak dengar macam itu, Andak takutlah. Dia sudah hendak bagi parang. [53] From her house SP7 clearly saw the accused banging on the front door of SP21 's house with the parang. On breaking the door, the Appellant put his hand through the broken part of the door and unlocked the door from the inside. [54] She saw the Appellant enter the house. After a few moments the children's cries could no longer be heard and there was silence. She then saw the Appellant come out of the house a few minutes later. There was blood on his hands and the parang he was holding. He then went in the direction of the school. [55] SP17, described in detail what happened inside her home which led to the death of her three children and the injuries inflicted on her by the Appellant. [56] SP17 testified that on17.5.2018 she was in the house together with SP19, SP21, the three deceased children and SP17's mother. At that time her mother's eyesight was bad and she could not walk. On the day in question SP21 had left the house to go to religious class at about 2.15pm. [57] SP 17 proceeded to mix milk for the first and second deceased in the kitchen. She then heard the sound of a motorcycle and shouting outside the house. She thought nothing of it and continued mixing the milk. [58] She then got a call from SP21 using the neighbor's phone. SP21 told her mother "Mak, ahik Rambo pukul akak". The phone then went dead. She then saw through the window the Appellant on a motorcycle coming from the direction of the school to the path leading to her house. The Appellant was shouting for "Zam" (SP19) to come out of the house "Zam, kau keluar". [59] SP19 was sleeping in the bedroom. SP17 woke him up and told him "Abang, Yang datang mengamuk". On hearing this SP19 locked the front door and told SP17 to call for help. SP19 then went out through the back door to get help. [60] SP17 stated that the Appellant was hitting the front door with the parang. A part of the door broke and the Appellant managed to put his hand in and unlock the door from the inside. At that time the first deceased was by the side of SP17. [61] On entering the house, the Appellant was searching for her husband. The Appellant asked SP17 "Di mana Zam". SP17 replied that SP19 was not there. [62] The Appellant then attacked SP17 with the parang. He used the parang to hit her almost severing her left hand. He then swung the parang continuously at SP17 injuring her right hand as well as her face. Her right thumb was almost severed. She said that she was trying to protect herself with her hands from the blows of the parang. She identified the parang as P93(B). [63] SP17's mother who was at the time at the hall tried to placate the situation by saying "sudah sudah". The Appellant retorted by asking her to keep quite as she was an old woman. The Appellant did not do anything to her. [64] SP17 said that after attacking her the Appellant attacked the first deceased child who was next to SP17 and crying. The Appellant hit the first deceased with the parang and the first deceased stopped crying. [65] SP17 saw the first deceased collapse and bleeding from the neck. The Appellant continued to go in and out of the house looking for SP19. SP17 said that he also went out through the back door and entered through the front door. [66] SP17 then saw the second deceased child come from the direction of kitchen. His facial expression showed that he was in pain. He had his hand over his shoulder which was bleeding. The second deceased then collapsed in the hall near her. As the Appellant was going in and out of the house SP17 described what the Appellant said as he pointed to the second deceased child: SP17: Dia datang, lepas sambil dia masuk keluar masuk, dia sempat tunjuk anak saya Firash, "yang ini sudah mampus dah" katanya. [67] In order to save her life SP17 dragged herself to the kitchen. She could not stand as her right knee was severely injured because the Appellant had hit her there several times with the parang. She managed to reach the bathroom towards the back of the house. [68] As she leaned on the bathroom door SP17 asked the Appellant why he had done this to her children. He told her he wanted to eliminate the descendants of SP19. The Appellant then attacked her once again with his fist by punching her on the left side of her head. This was how SP17 described the exchange: Masa itu saya bersandar dekat dinding bilik air saya, lepas itu masa saya bersandar itu Yang itu ada datang serang saya, lepas itu saya ada cakap dengan dia, saya cakap "sudahlah Yang, kenapa engkau buat anak-anak aku macam ini", dia cakap "Laki engkau itu tidak guna, aku hendak hapuskan kau, keturunan Zam" dia cakap. TPR: Lepas itu apa dia buat dekat puan lepas dia cakap? SP17: Dia tumbuk kepala saya, disini. JB: Dia tumbuk kepala saya di sebelah? SP17: Di sebelah kiri. TPR: Dia ada kata "Laki engkau tidak guna, hendak hapuskan keturunan Zam"? SP17: Dia cakap "aku memang hendak hapuskan keturunan Zam". [69] As she was leaning against the bathroom door she could see the body of the third deceased child lying outside the house near the back door. She could see him only from waist down as her view was blocked by a wall. SP17 said she heard him cry before she saw his body there. [70] Seeing the door to the store room open, SD17 dragged herself into the storeroom and locked the door from the inside by pressing the knob button. According to SP17 the Appellant was still looking for her in the house. She heard him say "mana seorang lagi ini, tidak mampus lagi ke" while she was in the storeroom. [71] The Appellant never found her there. SP17 saw that the Appellant's clothes were bloodstained when he was in the house. SP17 stayed in the storeroom until she was found by Nor Farah Binti Misrun (SP18) from Jabatan Petahanan Awam Malaysia (JPAM). SP17 was later brought to the Teluk Intan Hospital. [72] SP17 identified P40(8), P40(14) and P40 (20) as the photographs of the position of the bodies of the first, second and third deceased respectively at the house after the incident. [73] During cross examination SP17 denied that the Appellant had told her that SP19 had defamed the Appellant by saying that the accused had an incestuous relationship with his mother. [74] She also denied that the Appellant had said that SP 19 had cheated him. She agreed with counsel that the Appellant had told her he was angry that she and her husband had unnatural sex as it was against their religion. [75] She did not know whether SP19 and the Appellant were taking drugs. She did not agree that the Appellant was insane as he could recognize everyone in the house and could talk to SP17 and her mother. She also disagreed with counsel's suggestion that SP19 had gone out of the house on the morning of 17.5.2018 to work with the Appellant. [76] SP19 stated that SP17 was his wife and they stayed at the house together with the three deceased children, SP21 and his mother in law. He knew the Appellant and they did some work around the kampong. The Appellant had joined him about five to six months prior to the incident. He would pay the Appellant according to the amount of work done. [77] On 17.5.2018 he did not do any work as he was determined to fast with his family. At about 2.00pm as he was sleeping he was awakened by his wife to tell him that SP21 had called saying that the Appellant had hit her. [78] He then heard the accused motor cycle. He heard the Appellant shout words like "haram jadah, aku bunuh kamu Zam". On hearing this he locked the front door. He told his wife to call for help. [79] He then ran out of the house shouting loudly for help. He thought the Appellant would chase him. He did not think that the Appellant would act in such a way as to cause harm to his family. PEG: ...Encik, saya pun tergerak satu kecemasan berlaku, kamu sepatutnya pergi jiran terdekat bawa semua orang. SP19: Saya tidak sangka saya orang datang hendak bunuh anak isteri saya, ingat dia kejar saya. Saya ingat dia tidak buat anak isteri saya. [80] After going out of his house SP19 managed to seek shelter in one Pak Ngah's house. He was there for about one hour. When he was brought back to the house he was informed that his wife and children had all died and the police had taken the Appellant away. He did not go back in as he felt there was no longer any reason to do so. This is how he described his situation: Saya rasa macam sudah tiada apa-apa disitu, tidak bermakna bagi saya sebab mereka sudah kata anak isteri sudah tiada masa itu. [81] It was later that he found out that SP17 and SP21 were still alive. He identified the parang P93B and the sheath P94A as used by the Appellant for work. [82] He identified the bodies of the three deceased children taken at the hospital for the postmortem. He testified that photographs P47(15), P48(22) and P49(38) showed the bodies the third deceased, the first deceased and the second deceased respectively. [83] During cross examination SP19 denied that he had left the house that morning to consume syabu with the Appellant. SP19 disagreed that he bought drugs from a pusher called Ujang. He was not sure whether the Appellant took drugs while working with him because of the hard work. [84] He also denied counsel's suggestion that the Appellant was finding for him as he had cheated the Appellant of money in connection with work. He also denied that he did not ask for help when he ran out of the house. [85] He disagreed with counsel that had SP19 remained in the house and cooperated with the Appellant the latter would not have done what he did. [86] SP19 also denied that he had told the Appellant that he had unnatural sex with SP17 and this made the Appellant very angry as the latter felt that that was disgusting. [87] SP19 denied that he teased the Appellant or spread rumours that the Appellant was unmarried and had an incestuous relationship with his mother. [88] SP19 did not know that this triggered the Appellant's anger which led to the incident that morning. [89] SP19 testified that about a week before the incident he had a misunderstanding with the Appellant over money in respect of work done by them. [90] The Appellant was angry because he was being paid less than what he ought to be paid. This led to SP19 arranging for them to see the ketua kampong to solve the matter. From that day on the Appellant had been cold towards SP19. [91] After SP6's call to SP14 at the Balai, Koperal Mohd Saiful Bahari bin Bakhari (SP30) and Konstable Mahfuz bin Md Isa (SP31) were ordered to go to the school. According to SP30 he was informed by SP 14 that there was a man who had run amok in front of the school. [92] On arrival at the front of the school at about 2.40pm, SP30 and SP31 searched for the Appellant within the vicinity of the school. They managed to spot the accused holding a parang in his right hand talking to an old man known as Pak Andak. On seeing SP30 the Appellant ran away. SP30 was in his police uniform at that time. [93] Whilst the search for the Appellant was going on SP30 saw a man known to SP 30 as "Ustaz" fall of his motorcycle in front of him. This person was later identified as Mohd Redhuan Bin Embi (SP23). [94] SP23 was a resident of Kampong Sungai Haji Muhammad. He was a teacher teaching Pendidikan Islam at SMK Rungkup, Bagan Datoh, Perak. According to SP23 he was returning to Kampong Sungai Haji Muhammad from SMK Rungkup by motorcycle on 17.5.2018. [95] He was wearing a helmet at that time. He left SMK Rungkup after work at about 2.30pm. The journey back took about 20 minutes. On reaching the kampung he found it deserted. He thought it could be because it was the first day of the fasting month and the people were indoors. [96] As he was approaching the school he came across the Appellant carrying a parang. He had known the Appellant before as the Appellant had done some work for SP23's father. [97] He knew the Appellant by the name "Rambo". He also said that the clothes the Appellant was wearing were stained. As the Appellant was carrying a parang he thought that he was coming from work. [98] He acknowledged the Appellant by raising his head. The Appellant suddenly ran forward and slashed SP23's face with the parang. SP23 was injured in the right cheek. SP23 then speeded off in shock. He saw SP30 and SP31 ahead but fell off his motor cycle because he felt weak. He was then helped by SP30 and SP31. [99] SP23 still bore the scar on his right cheek. He confirmed that the injury he sustained is as depicted in photograph P42. He also identified the helmet (P36A) he was wearing at that time. The helmet also bore the mark made by the parang on it. The identified the parang P39B as the type used by the Appellant on him. [100] He was later brought to hospital for treatment for his injury. He did not know why the Appellant injured him as there was no quarrel between them. He also denied that he sounded his horn at the Appellant which startled him. [101] After helping SP23, SP30 contacted the Balai for help to apprehend the accused. Shortly thereafter three other police personnel including Koperal Mohamad Rashidee Bin Husin (SP32) arrived. SP30 and the other members of the police team found the Appellant roaming around about 70 meters from the school. [102] A struggle ensued between SP30 and the Appellant when the police team wanted to apprehend the Appellant. SP30 managed to wrest the parang from the Appellant. SP30 sustained superficial injuries namely "right upper limb abrasion over mid-forearm and right hand" in the struggle. [103] It was after the arrest of the Appellant that SP30 noticed that the Appellant's clothes were blood stained. He identified the photograph P45(1-2) as depicting the condition of the Appellant's clothes at the time of arrest. SP30 seized the parang and its sheath. [104] He identified the parang as P93(B) and the sheath as P94(A). The sheath was tied around the waist of the Appellant at the time of arrest. He identified the parang and sheath through the markings he made on them. He had marked the parang "S1" and placed his signature and the date 17.5.2018 and on it. [105] Likewise, he marked the sheath "S2" placed his signature and date 17.5.2018 on it. He marked "S3" (P95A) and "S4" (P96A) respectively on the shirt and pants worn by the Appellant. [106] He dated them 17.5.2018 and put his signature on them. He also prepared a search list P136 listing the items seized at the place of arrest. [107] He clarified that he only seized the parang and the sheath at the place of arrest. The clothes worn by the Appellant were seized at the Balai. From the search list the arrest took place at about 2.50pm. The parang P93(B) and its sheath P(94A) and the Appellant were brought back to the Balai by SP32. [108] Later SP32 seized a motorcycle in front of SP17's house bearing registration number BDY5195 which had been identified as having been used by the accused. He identified the motorcycle through the photographs P45(1-2). Upon further investigation it was found that the motorcycle was a stolen motorcycle. [109] All the items seized including the parang and the clothes worn by the Appellant were later handed over to the investigating officer of the case ASP Subkey (SP34) by SP30. [110] SP30 lodged 3 police reports in respect of the arrest of the Appellant. Of relevance was Rungkup Report 82/18 (P137) with regard to the arrest of the Appellant and Rungkup Report 826/18 (P139) in respect of the struggle he had with the Appellant in the course of apprehending him. [111] Photographs P40(7), (11) and (19) were referred to SP31 as showing the position of the bodies of the three deceased children as he found them when he entered the house. SP30 noted the front wooden door of the house had been broken. [112] SP30 later informed his superiors of the discovery and secured the house. He identified the photographs in P39(1-11) and P40(7-14) as depicting the condition in and out of the house at the time of his arrival with SP31. Thereafter a medical team was called in. Analysis of Appellant's blood sample [113] Of relevance to the fact as to whether the Appellant had consumed any drugs prior to the incident is the evidence of Dr. Sharmilah A/P Kuppusami (SP15). [114] SP15 is the Ahli Kimia di Sahagian Toksikologi Pusat Analisis Sains Forensik, Jabatan Kimia Malaysia, Petaling Jaya. She stated that on examining the blood sample taken from the Appellant she found it to contain the metabolic delta-9-tetrahydrocannabinol which is a main active ingredient in cannabis which is also known as "ganja". Reference was made to Laporan Kimia 18- FR-B-11742 (P113) which was prepared by SP15. [115] According to SP15 the amount of this active ingredient however was so small that it would not have any effect to the behavior of a person. This was what emerged during examination in chief: "TPR: Merujuk kepada kuantiti yang dikesan dalam spesimen darah ini, boleh Doktor nyatakan berapa, amount? SP 15: Amount yang dikesan 0.02 mikrogram per milimeter dan pada paras tersebut metabolic THC-COOH tidak memberi kesan kepada kelakuan seseorang. TPR: Bermaksud amount ini adalah satu amount yang banyak atau sedikit atau bagaimana dalam layman term? SP15: Dalam layman term sedikit, a mat sedikit. TPR: Tidak memberi kesan kepada kelakuan seseorang? SP15: Hmm. It doesn't alter person behaviour." [116] During cross examination she agreed that drugs like Eramine, Syabu and cannabis can cause a change in the behavior in a person. Shabu consumed can cause aggressiveness in a person. She also stated cannabis can be traced in the blood longer than other drugs. The cannabis could be detected in the blood for up to 36 hours after consumption. [117] As for Eramine and Methaphetamine these drugs could be detected in the blood only up to 24 hours after being taken. SP15 was of the view that for someone who had consumed "Syabu, Meth or whatever drugs" if the blood samples were taken on the day itself it will show that result. It is not in dispute that the blood sample of the Appellant was taken on 19.5.2018 at about 2.30pm. [118] As to the window period of detection for syntactic drugs much would depend on the metabolism rate of the individual. This is what she said: "When it come sintectic drugs like Methamphetamine and Eramine that is very fast metabolise drugs which the body Metabolise quickly within few hours, maybe 6 hours, 8 hours, depending on that person, Metabolisme rate of each individual is different, so based on that person". [119] The HCJ after having evaluated the prosecution case found that they had made out a prima facie case against the Appellant in respect of all the charges and proceeded accordingly to call for the Appellant to make his defence on all the charges. The Defence [120] After the three (3) alternatives consequent upon such a finding were read, the Appellant elected to give an unsworn statement from the dock. [121] The other witness for the defence was Dr. Ian Lloyd Anthony (SD2). [122] The Appellant read out his statement in court. [123] The Appellant in his statement (D148) stated that he was born and raised in Kampung Sungai Haji Muhammad. In 2014 he worked as a labourer. In 2017 he started to do kampong work. He used the parang during his work. The parang was always tied to his waist for convenience. [124] He first started working with SP19 around 2017. [125] Although SP19 was not from the Kampong he could get work as he was a sweet talker and good negotiator. SP19 however also taught the Appellant to smoke drugs like syabu, five and ganja (cannabis). [126] Taking the drugs prevented him from getting tired while working. He took ganja as it made him feel relaxed. He took drugs day and night from 2017 onwards. He sometimes heard whispers in his ear. [127] He began the day on 17.5.2018 by buying breakfast for his mother. The then fed his cows. At about 10.00 am he went to SP19's house. They then proceeded to Pak Andak's oil palm plantation on SP19's motorcycle to work. [128] All along the way to work he was venting to SP19 his frustration and how disappointed he was about work-related matters. In his statement he said that SP19 was dishonest and had cheated him of his wages in respect of work carried out together. [129] Every time he questioned SP19 about work SP19 would give a distorted story. He also complained that SP19 took a long time to prepare for work and he had to wait long for SP19 outside SP19's house. [130] On reaching Pak Andak's plantation SP19 gave him a new drug to forget about his dissatisfaction about work. SP19 told him it was good stuff (barang baik). [131] SP19 told the Appellant that the Appellant was confused and the new drug would calm him down. According to the Appellant the new drug was different. After taking the drug he and SP19 started to do their work. [132] The Appellant then felt unwell and asked SP19 to send him home. [133] On reaching his home the Appellant laid on a swing. [134] The Appellant was thinking about things which made him feel dissatisfied with SP19. Apart from SP19 cheating him of his wages he was also disappointed that SP19 had told him that he had unnatural sex with SP17 which was against the religion of Islam. [135] The Appellant was also offended that SP19 had accused him of having an incestuous relationship with his mother. [136] He then fell asleep and did not know what happened after that. He only knew that he was arrested by the police and that they said he had killed a few people, namely SP19's children. [137] He asserted in his statement that he did not have any intention nor planned to kill SP19's children. They had nothing to do with the matter between him and SP19. He did not know or realised what had happened until after he woke up from his sleep. [138] The second witness, SD2 was the Consultant Forensic Psychiatrist, Hospital Bahagia Ulu Kinta, Tanjung Rambutan. [139] There is a court order dated 25.3.2019 where it was previously ordered that the Appellant undergo observation at the Hospital Bahagia Ulu Kinta under section 342 Criminal Procedure Code. [140] As a result of his observations SD2 made a report as to his findings (P111). [141] SD2 testified that the Appellant did not have any history of psychiatric illness prior to his admission to Hospital Bahagia Ulu Kinta. [142] In his report SD2 stated that the Appellant was fit to plead and that the Appellant was sane at the time of the commission of the offences and that he knew the consequences of his actions and could know what he was doing was wrong and against the law. [143] The Appellant has been under the observation of SD2 for a duration of one month from 25.3.2019 to 24.4.2019. In the course of this observation SD2 had interviewed the Appellant personally 11 times on 11 separate days. [144] The purpose of the repeated interviews was to ascertain the veracity of the information and the mental state of the Appellant. SD2 confirmed that the information obtained from the interviews were "good and reliable". [145] SD2 had also interviewed members of the Appellant's family namely his mother, brother and uncle at his home. These interviews consisted of a detailed psychiatric evaluation, ward observation and CCTV observation in the ward. [146] From his direct examination of the Appellant, SD2 found that the Appellant had been abusing three types of drugs namely "methamphetamine and eramine, nimetazepam". SD2 also said that the Appellant had been using cannabis since his teens and methamphetamine since 2010. [147] On being questioned by counsel he said that cannabis had a window detection period of 10 to 45 days depending on the amount consumed. As for methamphetamine and nimetazepam the period would be shorter detection period of up to 3 days or 72 hours as these drugs were water soluble. [148] SD2 was of the view that prolonged drug abuse may or may not cause disruption of one's cognitive abilities. As to whether prolonged synthetic drug abuse can cause psychosis, he stated that generally psychosis can be experienced in users of methamphetamine especially if the use is excessive. [149] He however said that this was only a possibility and does not happen in all cases. He stressed that whether it was long term or short term, it would depend on the individual's susceptibility. In answer to a question from the court he agreed that the matter was "very subjective". [150] He also said that someone with a problem of prolonged drug abuse could cause mania problems but this was uncommon. Finally, in answer to the question by counsel whether prolonged use of methamphetamine could cause depression SD2 opined that as methamphetamine was a stimulant drug, depression was not a feature in methamphetamine. [151] SD 2 elaborated that if a person takes a particular amount of drugs he can maintain his three areas of functioning, namely cognition, coordination and speech. [152] However, if he took an excess of the drug he would go into a state of intoxication. Because of this his cognitive capacity would be affected. On the other hand, if he stopped taking the drug and go into a state of substance withdrawal, this too would affect his cognitive capacity. [153] Specifically referring to the Appellant, SD2 was of the opinion that he did not think the substance abuse or his substance dependence had affected his mental faculties at the time of the offences. [154] He agreed with the DPP that this meant the Appellant's faculty to choose between right and wrong was intact. SD2 was also of the opinion that from his observation the Appellant never experienced any psychotic phenomena. This was how SD2 expressed his opinion on the issue: TPR: Furthermore Doctor, regarding the psychosis, psychotic disorder in this case, does the accused fulfil the diagnosis of substance induced psychotic disorder? S02: Yang Arif, the accused has never experienced any psychotic phenomena. When I say psychotic phenomena Yang Arif, I mean in the term of hallucination and delusion. These are the 2 psychotic symptoms. The accused has never experienced psychotic symptoms mean hallucination or delusion while under the influence of cannabis, methamphetamine or for that matter nimetazepam. [155] As to the question whether the Appellant suffered from any intoxicant effect as a result of substance abuse, SD 2 responded as follows: "Yang Arif, I examined the accused in the relation to the possibility of him being intoxicated at the time of the alleged offence. In assessing whether a person is intoxicated by virtue of consuming drug in this case, it's not just one particular drug, it is 3 different drugs. We have to look into 3 main areas of assessment. The first area is cognition. Under cognition, we have to assess his orientation, whether he was orientated to time, place and person at that particular point of time. So from my assessment, it was clear to me that he was orientated to time, he was able to tell me exactly when the offence happen. He was orientated to place, he was able to tell me exactly where he went during the course of the offence in the victim's home as well as the school. He was also able to identify certain individuals, who he have countered throughout the course of the day, named the victims at their own homes, the 3 victims, the children, the mother of the 3 children, the father of the victims as well as an uncle who he have countered just outside the school. He was also able to identify that there was a security guard posted at the gate of the school. That tells me that he was, his orientation was intact. He was orientated to time, place and person. With regards to his cognition as well besides orientation, we have to look into his ability in terms of his memory and understanding. From my assessment of the accused, I found that his memory was intact. He was able to recall all the details pertaining to the alleged offence quite clearly. That is the first area, cognition. The second area of assessment in relation to a person whom we suspect could be intoxicated would be coordination, motor coordination. Now a person in the state of intoxication may from drugs alcohol, we would expect him to have some abnormality in his gait, unsteadiness in movements, involuntarily movements of the limbs such as tremors, shakes. Intoxication to a level that you'll be unable even operate a motor vehicle. In this case, the accused was able to ride a motorcycle on that day of the offence. This tells me that his coordination was preserved. The third area is speech or language. When a person who is intoxicated, one would expect that the speech is slur or incomprehensible. However, in this case, I found that he was able to articulate words that he had told me that he had uttered during the course of the event on that day. It was quite clear that the accused was able to recall. So from these 3 areas of assessment, cognition, coordination and speech, I'm able to opine that he was not under the state of substance intoxication at the time of the alleged offence".
