A man who was charged with the attempted murder of a woman at Kallang Wave Mall in July last year, pleaded guilty to attempted culpable homicide causing hurt on Monday (Nov 2).
He was sentenced to 5.5 years in jail. Another two charges for possessing weapons were taken into consideration during sentencing.
Chua Jing Yuan, a 27-year-old Singaporean, stabbed the 31-year-old in the chest that day.
She was with her boyfriend and an acquaintance drinking in a bar at the mall when the incident happened.
According to charge sheets, Chua stabbed her with a knife at about 1.20am when she went to the restroom.
The court heard that he was suffering from major depressive disorder with psychotic features.
He was first seen at Jurong Polyclinic in May 2021 for anxiety, and later referred to Ng Teng Fong General Hospital, where he was diagnosed with generalised anxiety disorder with obsessive compulsive symptoms.
After undergoing treatment, Chua was said to have improved, but defaulted after an appointment in March 2023.
His condition then worsened, eventually acting on a voice telling him to kill someone before taking his own life.
On July 13, 2025, Chua bought items including black clothes, backpack and face masks, a box of gloves, a bottle of bleach, a claw hammer and a kitchen knife from Jurong Point.
He then packed the items into the backpack and changed into the new clothes, before placing his old items into a riser compartment at a stairwell near his sister's flat.
Chua did so for his family to find them after he died.
After carrying out the attack, he tried to leave Kallang Wave Mall but tripped and was restrained by the victim's boyfriend and acquaintance.
They removed the hammer from his backpack and threw it away, with passers-by stepping in to help subdue Chua while waiting for police officers to arrive.
He was arrested by about 1.30am, and purportedly asked attending officers to shoot him when he was arrested and tried to harm himself.
He was taken conscious to hospital by attending paramedics.
The woman underwent surgery and was discharged the day after the incident. The court heard that she did not suffer any significant injuries or disabilities.
According to Institute of Mental Health senior consultant physician, Dr Kenneth Gerard Koh Wun Wu, Chua's condition significantly contributed to his offending as it severely compromised his judgement.
Dr Koh found Chua to be severely depressed, with "mood-congruent auditory hallucinations".
He added that Chua's condition would have qualified him for a defence of diminished responsibility, as his depression was severe and had badly compromised his judgment.
The defence of diminished responsibility is a partial defence for murder.
If an accused is suffering from substantial impairment of their capacity to know the nature of their actions that caused death, then the criminal liability of a person accused of murder may be reduced to culpable homicide not amounting to murder.
Notwithstanding the clinical findings, the 27-year-old, represented by Choo Si Sen and Choo Yean Lin from Tan Lee & Partners, was not found to be of unsound mind at the time of the offence and was fit to plead in court.
The offence of attempted culpable homicide causing hurt carries a fine, imprisonment of up to 15 years, caning, or a combination of these punishments.

去年 7 月在加冷购物中心企图谋杀一名女子的男子，于周一（11 月 2 日）承认犯有过失杀人未遂罪，造成他人受伤。
他被判处五年半监禁。量刑时，另有两项非法持有武器的指控也被考虑在内。
当天，27岁的新加坡人蔡景元用刀刺伤了这名31岁男子的胸部。
事发时，她正和男友以及一位熟人在商场的酒吧喝酒。
根据起诉书，蔡某在凌晨 1 点 20 分左右用刀刺伤了她，当时她去洗手间。
法庭获悉，他患有伴有精神病症状的重度抑郁症。
他于 2021 年 5 月首次因焦虑症在裕廊综合诊所就诊，后来转诊至黄廷方综合医院，在那里他被诊断出患有伴有强迫症状的广泛性焦虑症。
据称，蔡女士接受治疗后病情有所好转，但在 2023 年 3 月的预约后失访。
之后他的病情恶化，最终听从一个声音的指示，在自杀前杀了一个人。
2025年7月13日，蔡某在裕廊坊购买了黑色衣服、背包、口罩、一盒手套、一瓶漂白剂、一把羊角锤和一把菜刀等物品。
然后他把东西装进背包，换上新衣服，再把旧东西放到他姐姐公寓附近楼梯间的储物格里。
蔡先生这样做是为了让家人在他去世后能够找到他。
实施袭击后，他试图离开加冷购物中心，但被绊倒，并被受害者的男友和熟人制止。
他们从蔡某的背包里取出锤子并扔掉，路人上前帮忙制服蔡某，等待警察到来。
凌晨 1 点 30 分左右，他被逮捕。据称，他在被捕时要求到场的警官开枪打死他，并试图伤害自己。
他被到场的医护人员以清醒状态送往医院。
该女子接受了手术，并在事发次日出院。法庭获悉，她没有遭受任何严重的伤残。
据心理卫生学院高级顾问医师许文武医生称，蔡某的病情严重影响了他的判断力，从而导致他犯罪。
Koh 医生发现 Chua 患有严重的抑郁症，并伴有“与情绪相符的听觉幻觉”。
他还补充说，蔡某的病情符合精神障碍抗辩的条件，因为他的抑郁症很严重，严重损害了他的判断力。
精神责任能力减弱的辩护理由可以作为谋杀罪的部分辩护理由。
如果被告人因行为导致他人死亡而丧失了辨别其行为性质的能力，那么被控谋杀的人的刑事责任可能会减轻为过失杀人罪。
尽管有临床检查结果，但由 Tan Lee & Partners 律师事务所的 Choo Si Sen 和 Choo Yean Lin 代表的 27 岁男子被认定在犯罪时精神正常，能够出庭受审。
故意杀人未遂致人受伤罪可处以罚款、最高 15 年监禁、鞭刑或上述刑罚的组合。
