The Circuit Road murder trial began at the
High Court on 18 September 2019, with both the leading criminal lawyer
Eugene Thuraisingam and his colleague Chooi Jing Yen representing Boh Soon Ho, who was then 51 years old. High Court Judge
Pang Khang Chau was assigned to hear the case, and the prosecution – consisting of Wong Kok Weng and Joshua Chua – proceeded with the charge of murder by intentionally causing a bodily injury that could lead to death in the ordinary cause of nature. Should Boh be found guilty of this charge of murder, he could receive either the
death penalty or
life imprisonment. Boh also faced two charges of having sexual intercourse with a corpse and dishonest misappropriation of a deceased person's property, which warrant sentences of up to five years' jail, and up to three years' jail respectively, in combination to a possible fine for either one or both of these offences.
Boh's account and defence Boh, who recounted his past and relationship with Zhang on the stand, revealed in court that on 18 March 2016, three days before the date of Zhang Huaxiang's murder, he happened to see a man together with Zhang outside her flat. Zhang had been seeing Boh less and less since January 2016, and in combination with his prior suspicion relating to this, Boh grew more certain that Zhang was seeing someone else and began to think that she was cheating on him, despite their true relationship being not lovers from the start. This sighting also made Boh angered at how Zhang did not reciprocate his feelings after thinking of the huge sum of money he spent on her meals and gambling. On 21 March 2016, Boh invited Zhang to come to his landlord's flat at Circuit Road for lunch. After their meal of steamboat, Boh began making advances on Zhang, wanting to become physically intimate with Zhang, who rejected his advances and called him crazy. Then, Boh confrontationally asked her about the man he had seen her with. She told him that it was a man from
China, with whom she went out together for a few times and whom she had interest in, and she added that her former boyfriend had come to visit her from China and it was normal for them to be intimate. As a result of this answer, Boh became furious and he took a blue towel from his bathroom to wrap around Zhang's neck and strangle her from behind, which caused Zhang to die from suffocation. Upon seeing Zhang's lifeless body, Boh took off Zhang's clothes and placed the body on his bed, and proceeded to take photos of Zhang's nude corpse. Afterwards, Boh molested Zhang's corpse and tried to have sex with her dead body, but was unable to sustain his penile erection. Afterwards, Boh bought new luggage with intention to contain the body before abandoning it, but it could not fit as it had become stiff. Boh thus packed up his bags and left for
Malaysia the next day, where he stayed on the run until his arrest on 4 April 2016. Boh's lawyers Chooi and Thuraisingam argued that Boh should be liable to a defence of sudden and grave provocation, as Boh, who was deeply infatuated with Zhang, was provoked and angered by Zhang's comments of going out with someone else and did not reciprocate his feelings, and the overwhelming sense of rage and jealousy caused Boh to suffer from a loss of self-control and he consequently strangled Zhang to death. They also argued that with Boh's low IQ of 74, and his lack of experience with women and low social skills, this also contributed to Boh's reaction to Zhang's comments and thus lead to this fatal outcome. Boh, who recounted his crime through a Chinese interpreter, also insisted that he only used the towel to "scare her", and had no intention to strangle Zhang or kill her despite having used the towel on her while his emotions get the better of him.
Prosecution's arguments However, the prosecution argued that Boh did not carry out the strangulation out of impulse or in a moment of anger. They drew attention to the fact that the relationship between Zhang and Boh were not intimate and there was no basis for a person in Boh's position to feel provoked, and he committed the killing due to rage and jealousy, as a result of not having his desire of sex fulfilled and no reciprocation of his feelings. The prosecution's psychiatrist, Dr Stephen Phang of the
Institute of Mental Health, revealed in his report that Boh was not suffering from a mental disorder that diminished his responsibility and there was no grave and sudden provocation, based on his decision to attempt to dispose of the corpse and prepare to escape from Singapore, which demonstrated his coolness and significant amount of self-control over his actions. Additionally, Boh's sexual assault of Zhang's corpse also proven that the defendant "was purposeful in his pursuits for personal pleasure", according to Dr Phang, who also disagreed that Boh was delusional in thinking his unrequited feelings for Zhang was love.
Conviction and sentencing verdict On 7 February 2020, the trial judge
Pang Khang Chau found Boh guilty of murder for the fatal strangulation of Zhang Huaxiang. He stated that Boh failed to prove that he killed Zhang out of grave and sudden provocation, due to him still possessing a significant amount of self-control at the time of the alleged provocation, though the judge still accepted that Boh was indeed provoked into doing the deed despite his extent of provocation not sufficiently grave enough to make him liable to a successful defence of sudden and grave provocation. Besides that, Boh's relationship with Zhang was not mutual romance and it was also not sexual, so even with Boh's one-sided feelings for Zhang, Zhang's comment of her closeness with her ex-boyfriend could not be considered as a grave and sudden act of provocation to a reasonable person in Boh's position and contextually from the nature of their relationship. Given that the psychiatric evidence did not support the notion of Boh suffering from any abnormality of the mind or mental disorder, and it revealed that Boh was not intellectually disabled and had no problems with his daily functioning despite his low IQ of 74, the judge dismissed Boh's second defence of
diminished responsibility. The prosecution decided to not seek the
death penalty (the maximum penalty for murder) and instead argued for Boh to be sentenced for life behind bars. The next day, on 8 February 2020, Justice Pang sentenced 51-year-old Boh Soon Ho to
life imprisonment. Justice Pang noted that based on the sentencing principles inherited from the
Kho Jabing case, and according to the prosecution's submissions, Boh did not exhibit a blatant disregard for human life or viciousness when he strangled Zhang to death, and he did not premeditate the murder despite having ample motive by jealousy to commit the killing. Other factors such as Boh's low IQ and remorse over the crime were also duly considered by the judge during sentencing. Although his life sentence was taken to mean spending the rest of his natural life in jail, Boh will be entitled to a possible chance of release on parole after spending at least 20 years in jail provided that he displays good conduct while in prison. No caning was imposed on Boh since he was 51 years old at the time of sentencing. On the same day of Boh's sentencing, Thuraisingam, who agreed with the prosecution's submissions for a life term in Boh's case, confirmed that his client would
appeal against his murder conviction. Boh's two other charges of dishonest misappropriation of Zhang's possessions and
sexual penetration of a corpse were also withdrawn by the prosecution at the end of Boh's murder trial. ==Appeal and imprisonment==
