The attacker, who was Low's ex-husband Seet Cher Hng (薛泽元 Xuē Zéyuán), had attempted suicide after stabbing his ex-wife eight times, but he was taken to hospital by the police and he survived his wounds.

Seet, who had a gambling habit, had been harassing his ex-wife for several years after their divorce for more money, alleging that his share of their condominium's sale proceeds was not fairly distributed.

[9] As a result of his anger and hatred towards his former wife, Seet Cher Hng decided to confront Low Hwee Geo and kill her.

He also penned a total of four suicide notes to his daughter, sister, a friend and to the police between April and July 2018; some excerpts of these letters were revealed in court during Seet's 2021 murder trial.

[11] On 19 July 2018, 66-year-old Seet Cher Hng rented a car and headed to the carpark of ITE College Central, where Low was working as the examinations director.

He arrived at about 4:40 PM and stayed inside his vehicle, waiting for Low to appear, as he intended to attack her once she entered her car.

While Seet was rushed to hospital, 56-year-old Low Hwee Geok was pronounced dead at the scene by paramedics of the Singapore Civil Defence Force (SCDF).

[12][13] Seet, who sustained grievous abdominal injuries, was rushed to the hospital, where he received surgery, which saved his life.

Low, who originally came from a Confucianist family, converted to Christianity on 25 December 2017 at the church and often went there with her daughter to make prayers.

This lesser charge dictates an offence of murder by intentionally inflicting an injury that could sufficiently result in death.

A month after the amendment of the charge sheet, Seet was officially brought to trial on 14 September 2021 for Low's murder.

The only other punishment for this charge was life imprisonment, which the prosecution did not object to when they expressed they would leave the sentence to the trial court's discretion.

However, the trial judge Aedit Abdullah of the High Court harshly reprimanded Wong for emphasising his mitigation plea on the numerous false allegations which Seet raised regarding the supposed financial disputes he had with Low.

Justice Aedit also pointed out that the matter raised in mitigation was irrelevant to sentencing, and that with the victim being dead, she was not given a voice to tell her side of the story regarding the monetary issues that Seet brought forward against her in his unproven assertions.

[29] Nonetheless, Justice Aedit found there were insufficient grounds in Seet's case which would have deserved the death penalty, given that in accordance to the Kho Jabing appeal ruling,[30][31] the death penalty was strictly reserved to the most serious cases of murder where an offender, despite falling short of the intention to kill, exhibited viciousness and/or a blatant disregard for human life, as well as sparking outrage in the community due to the murder.

The judge also stated that since the prosecution did not oppose to a life term, it would be "rare indeed for the court to impose a sentence not sought by any party to the proceedings.

"[1] As a result, on 22 September 2021, eight days after his conviction, 69-year-old Seet Cher Hng was sentenced to life imprisonment for Low's murder.

[37] The ITE College Central murder also brought renewed attention to several other high-profile cases involving family-related homicides committed in Singapore in the past few years.
