Sujay Solomon Sutherson (c. 1981 – 8 September 2022) was a Singaporean prisoner who was convicted of the manslaughter of his mother Mallika Jesudasan in 2012.

According to Sujay, Mallika asked him for money after they had their dinner on that fateful day, but he turned down her request and proceeded to the kitchen to wash his plate.

Sujay, who took a second knife from the kitchen and caught up with Mallika, and stabbed his mother in her throat in order to stop her from using the phone.

The second stabbing causing her to collapse, but despite being mortally wounded, Mallika writhed on the floor for some time and spoke unintelligibly.

Upon returning to the flat, Sujay's uncle detected a strong detergent-like odour coming from one of the rags found in the toilet.

He also noticed blood on the hand of his elder nephew, who lied to his uncle that he last saw his mother at the void deck after he passed her the food he bought from downstairs.

[7][9][13] Many neighbours were shocked to hear about the murder, with one of them stating that Mallika was a "warm and friendly woman" who greeted them and would give them cookies during Chinese New Year.

[21] Sujay was not represented by a lawyer during his trial, while the prosecution was led by Deputy Public Prosecutor (DPP) Kumaresan Gohulabalan.

Dr George Paul, a forensic pathologist, testified that based on his autopsy findings, Mallika died from multiple stab wounds to the neck and either one of the injuries inflicted by Sujay on his mother would have been sufficient in the ordinary course of nature to cause death.

He testified that he was forced to kill her in self-defence due to Mallika scratching his face during the quarrel and wanted to undress him, and even disputed portions of his police statement.

[28] In their final submissions, the prosecution sought the maximum sentence of life imprisonment, arguing that the case had "shocked the conscience" due to the cruelty and violence, and Sujay was a danger to society as he was "unpredictable, lacked insight into his mental illness", and was able to disguise his symptoms due to his above-average intelligence.

[29][30] On 15 September 2015, Judicial Commissioner Hoo issued her decision, sentencing 34-year-old Sujay Solomon Sutherson to life in prison.

Without a lawyer, Sujay made his own arguments before the appellate court's three-judge panel – Chief Justice and two Judges of Appeal Chao Hick Tin and Tay Yong Kwang – and asked that his sentence should be overturned.

[35] After his sentencing, Sujay Solomon Sutherson was incarcerated at Changi Prison, where he was serving his life term, which was backdated to the date of his remand on 29 May 2012.

Over the next seven years, Sujay would face another set of health problems, mainly vitamin B12 deficiency, and sensory ataxia – a loss of body coordination due to a nerve impairment.

Despite the weakness in his limbs, a prison officer noted that Sujay generally did not require physical assistance and had been independent, although he sometimes used a walking frame or wheelchair to move around.

Sujay was subsequently taken to Changi General Hospital (CGH) and admitted to the intensive care unit, where the doctors diagnosed him with septic shock, which was caused by an infection as a result of Sujay's low blood pressure, and his blood pressure level was dangerously low.

Despite the treatment for septic shock, Sujay's condition did not improve, and he was gravely ill to the extent that the doctors found it unsuitable for them to investigate the source of the sepsis.

Sujay eventually died from multiple organ failure as induced by septicaemia (blood poisoning) on 8 September 2022.

He stated that in spite of the horrific end his sister met, he still loved his nephew and described him as a "well-behaved child of above-average intelligence" who was thoughtful and considerate, and he revealed that despite the knowledge of his condition, the whole family was shocked over the violence that Sujay exhibited in the killing of his mother.

In the three years since the incident, Sujay's siblings have also renovated the flat and continued to live there; the both of them were unable to attend the sentencing hearing of their brother due to one of them having work commitments while the other was overseas.
