Nagaenthran K. 2013-2017 psychiatric reports disproves he was intellectually disabled

Nov 14, 2021 | 🚀 Fathership AI

All 4 psychiatric experts opined that convicted drug mule Nagaenthran K. Dharmalingam was not intellectually disabled.

According to court documents seen by Fathership, 4 psychiatric experts gave their reports and testimonies on Nagaenthran's mental health assessment.

While all of the 4 psychiatrists agree that Nagaenthran has borderline intelligence, he was not mentally retarded.

Psychiatrists appointed by the prosecution

  • Two psychiatric reports from Dr Koh Wun Wu Kenneth Gerald dated 11 April 2013 and 7 February 2017.

    Dr Koh is a senior consultant from the Department of General and Forensic Psychiatry at the Institute of Mental Health (IMH)


  • A psychological report from Eunice Seah dated 12 April 2013.

    Eunice is a psychologist at IMH's Department of Psychology


  • A psychiatric report from Dr Patricia Yap dated 1 February 2017.

    Dr Yap is the Principal Clinical Psychologist at the IMH.

Psychiatrist appointed by Nagaenthran's legal defence team

A psychiatric report from Dr Ken Ung Eng Khean dated 22 August 2016.

Dr Ung is a psychiatrist from Adam Road Medical Centre.

Dr Koh's 2013 report

Nagaenthran was examined Dr Koh on 14 and 21 March 2013. Nagaenthran's sister was also interviewed by Dr Koh over the phone, as well as his prison officer.

Dr Koh's opinion:

Mr Nagaenthran had no mental illness at the time of the offence. Although not clinically mentally retarded, his borderline range of intelligence might have made him more susceptible than a person of normal intelligence to over-estimating the reality of the alleged threat that had been made to his girlfriend if he refused to make the delivery of the drugs. It, however, would not have diminished his ability to appreciate that the package that was taped to his thigh would most likely have contained drugs and that bringing this to Singapore was illegal.

Eunice Seah's 2013 report

Seah assessed Nagaenthran on 4 April 2013. She conducted first an interview followed by two psychometric measures. She also conducted the 'Test of Memory Malingering (TOMM)'. Nagaenthran's sister was also interviewed.

Seah's opinion:

In view of Nagaenthran’s performance on the various WAIS-IV (Wechsler Adult Intelligence Scales (Fourth Edition) indexes, socio-occupational history, education history, his adaptive functioning abilities and his presentation during the assessment, Nagaenthran is functioning at least within the Borderline range of functioning and he is assessed not to be intellectually disabled.

Dr Ung's 2016 report

Nagaenthran's then lawyer Eugene Thuraisingam appointed Dr Ung to conduct a separate psychiatric assessment.

Dr Ung assessed Nagaenthran on 19 April and 19 July 2016 and also relied on the findings made in Dr Koh's 2013 report.

Dr Ung's opinion:

I am of the opinion that Mr Nagaenthran suffered from an abnormality of mind at the time of his arrest, namely: Severe Alcohol Use Disorder, Severe Attention Deficit Hyperactivity Disorder ADHD) [sic] Combined Type and Borderline Intellectual Functioning/ Mild Intellectual Disability.

(Nagaenthran's IQ) is revealed to be 66 to 74. This is in the range of Mild Intellectual Disability suggested by the [the American Psychiatric Association]

Intellectual Disability requires the presence of functional disability as well and I am of the opinion that Mr Nagaenthran had functional disability in the conceptual domains and to a lesser extent in his social and practical domain.

Dr Yap's 2017 report

In light of Dr Ung’s Report, the applicant was referred by Dr Koh to Dr Yap for the purposes of conducting a neuropsychological assessment to explore the possibility that the applicant was suffering from ADHD.

Dr Yap conducted 7 assessments totalling 15 hours and 55 minutes in the period November 2016 to January 2017. 18 psychometric tests as well as a one-hour interview with Nagaenthran's sister on 29 December 2016.

Dr Yap's conclusion:

The results indicate that Mr Nagaenthran is not intellectually disabled...Additionally, testing revealed that while many of Mr Nagaenthran’s executive functioning skills were impaired, he was able to plan and organise on simpler items and there were no indications of problems with impulsivity and vigilance.

While there are some indications in the current assessment that Mr Nagaenthran may have adult ADHD, his account of the incidents leading to his arrest suggests that he acted in a pre-meditated fashion and understood the potential consequences of his behaviour.

Dr Koh's 2017 report

In a report dated 7 February 2017, Dr Koh made a few observations in response to the conclusions drawn in Dr Ung’s Report.

First, Dr Koh disagreed with Dr Ung that the applicant was mildly intellectually disabled.

The conclusions drawn in Dr Yap’s Report about the applicant’s intelligence are in agreement with those reached in Ms Seah’s Report: both Dr Yap and Ms Seah had concluded that the applicant was not intellectually disabled.

Second, Dr Koh rejected Dr Ung’s diagnosis that the applicant had ADHD. Dr Koh called into question Dr Ung’s reliance on the Adult ADHD Self-Report Scale (“ASRS”), given that the ASRS is a self-rating scale that carries the attendant possibility of bias. Dr Koh suggested that Dr Yap’s employment of the more objective Connor’s Continuous Performance Test (3rd Edition) (“CPT3”) was more instructive.

Dr Koh’s opinion was that even if the applicant has ADHD, his condition is mild, with features of inattentiveness, but not hyperactivity or impulsiveness.

Third, Dr Koh questioned Dr Ung’s diagnosis of severe alcohol use disorder, given that the applicant’s account of his alcohol use to Dr Ung greatly differed from that provided to Dr Koh when he was preparing his 2013 psychiatric report.

Dr Koh also acknowledged that the applicant’s “borderline intelligence and concurrent cognitive defects may have contributed toward his misdirected loyalty and poor assessment of the risks in agreeing to carry out the offence [that he was convicted for]”

Defence's psychiatrist initially suggested that Nagaenthran had intellectual disability but later admitted the contrary when cross-examined

Dr Ung's report had suggested that Nagaenthran suffered from mild intellectual disability:

I am of the opinion that Mr Nagaenthran suffered from an abnormality of mind at the time of his arrest, namely: Severe Alcohol Use Disorder, ADHD and Borderline Intellectual Functioning / Mild Intellectual Disability.

Intellectual Disability requires the presence of functional disability as well and I am of the opinion that Mr Nagaenthran had functional disability in the conceptual domains and to a lesser extent in his social and practical domain.

According to the court documents, Dr Ung later agreed during cross-examination, with Dr Yap's opinion that the applicant is not intellectually disabled.

Conversely, Dr Koh, Ms Seah and Dr Yap all opine in their respective expert reports that the applicant is not intellectually disabled, and merely suffers from borderline intellectual functioning.

Dr Ung's psychiatric report was highlighted by the judge to carry a tendency of bias and could not stand to scrutiny.

The judge also found Dr Ung's methodology and assessment of Nagaenthran to be unreliable.

新加坡7人“换妻”迷奸案细节公布!妻子被下药,全程录像直播...

Nov 03, 2022 | 🚀 Fathership AI

几名新加坡男子,在网上论坛认识后,沉浸在性幻想中无法自拔。

为了满足他们心中变态的好奇心,他们开始筹划换妻,并下药迷倒自己的妻子,让其他男子强奸自己的妻子!

昨天(10月31日),这起轰动新加坡一时的罪案在新加坡法庭进行了审理,涉案的七人中,有四人认罪,其中一人当场被判刑。

因为情况太过恶劣,为了保护受害人法院并未透漏她们的任何资料。被告人的名字也全部用字母代替。

回顾这起案件,这些男子的行径着实震碎了正常人的三观……

新加坡这名男子迷倒妻子 邀请其他人强奸并直播录像!

新加坡本体媒体《8视界新闻网》报道,法庭文件透露这起案件的主犯,是一名化名为J的新加坡男子。

J今年52岁,有着一份正当的工作,犯案时是一名业务拓展经理。这些年他和妻子一共生下了三个孩子,一家人原本很和谐地生活在一起。

不过在平静的生活下,J内心里涌动着一些邪恶的想法。

终于,在2010年,他在一个网络论坛上遇到了很多和自己臭味相投的人。在这个虚拟的平台,J肆无忌惮表露出自己的变态性癖,并发表了想玩换妻游戏的言论。

在这里,他们一起分享了很多有关“换妻”的想法。

聊着聊着,有一天他再也忍不住自己内心的想法,问自己妻子是否愿意接受3p。不出所料的,J的妻子拒绝了这个“提议”。

不过,这并没有阻止J付诸行动。

在一开始,包括J在内的一些人纷纷在家中安装网络摄像头。之后,他们会挑选时间告知网友相关的账号和密码,让他们自行观看自己和妻子的性爱视频。

经过一段时间后,J还是不满足。

于是,在某一天他下药迷晕了自己的妻子,然后邀请其他网友来家中与其发生关系!

随着事态的发展,J越来越沉迷其中……2013年,趁着妻子身体不适的时候,J还偷偷换了药物,再次邀请朋友来家中迷奸妻子。

这次,J竟然还打开了网络直播!

沉迷于“换妻游戏”,J不仅仅是让别人和自己妻子发生关系,同时他也跟其中一名网友K“商量好了”,趁着K迷晕自己妻子的工夫和她发生了性关系。

在某种程度上,K的行为更加恶劣,他甚至自己充当了摄像师的角色,拍下了J和自己妻子发生关系时的整段性爱视频……

渐渐的,J的妻子在不知情的情况下跟多人发生了性行为,相关视频还被上传到网络。

在当时,引起了相当多人的关注。

换妻行为曝光报警 更多人牵涉其中受重罚

J本以为这件事可以一直继续下去,不料在今年,他的妻子无意中看见丈夫手机在播放视频。

在好奇心的驱使下,她看到视频内容,这才恍然发现:

在过去的几年里,丈夫在暗地里进行了多次换妻活动,而自己在不知情的状态下被多次迷晕,在和他人强行强行发生关系后还被拍照记录……

拿着证据,J的妻子当面质问K,而K也承认自己曾经和昏迷的她有过性行为,并将自己妻子迷晕交给J的事实。

在得知真相后,J的妻子立即选择报警。随着案件的调查,调查人员惊讶地发现,还有更多人参与其中。

其中,有一名参加了J“举办的”换妻活动的L,也对自己的妻子如法炮制。

在一次在作案时,L的妻子尽管被下药后蒙住眼睛,在中途清醒了过来。

但L居然并未因此感到害怕而终止犯罪活动,而是要求自己一名同事P直接强行跟自己妻子发生关系,幸而L的妻子及时挣脱逃离,才免遭摧残。

之后,P在一封信中交代了全部经过,并表示自己不知道受害人并不知情才犯下罪案。

但法律并不会因为他的解释而对他开恩,最总P被判处三年监禁。他是涉案七名男子中,第一个被判刑的男子。

还有四人也已认罪,等待下一轮审讯。相信在严明的法律下,他们肯定无法逃脱坐牢。

不过,涉案情节严重的K在落网后,一再向警方和法官说自己有心理疾病,并要求医生为其检测,意图逃脱刑罚。

新加坡心理卫生院诊断后,确认了K患有偷窥症。但在审理中法官认为K对自己的非法行为是知情的,依旧是犯罪行为。

K对法院的说法表示不服,并要求开庭申辩。

但K的犯罪事实已被揭露,并且为自己的行为供认不讳,加上此案件牵连甚广,性质过于恶劣,估计也是难逃法律制裁。
