However, after the prosecution proved that both defendants had the intention to kill Chew in furtherance of committing armed robbery, Neoh and Lim were found guilty of murder, and sentenced to death on 8 November 1973.

[2] Upon reaching the wine shop, Sim witnessed one of the two male customers holding a revolver above Chew, who was shot in the chest and unconscious on the floor.

Lim, who worked as a construction labourer, was charged with murder the next day, and he was committed to stand trial together with Neoh for the killing of Chew.

[7][8] On 30 October 1973, the High Court conducted the trial of both Lim Kim Huat and Neoh Bean Chye for the murder of Chew Liew Tea.

[11] Lee also stated that he heard Lim saying that during the robbery, he held the victim Chew at gunpoint and told him in Penang Hokkien that he should not move or he would "splash" him.

[18][19] In response, the prosecution submitted that Lim intentionally fired the gun to kill Chew, and the death of Chew was caused in furtherance of the duo's common intention to commit robbery and by application of the provisions under Section 34 of the Penal Code, Neoh should be held equally liable to a charge of murder as Lim, since he and Lim shared a common intention to commit robbery and murder, and they had planned to use the gun to facilitate their crime and use violence if necessary, and made plans to wait for the opportunity to commit armed robbery.

[20][21] On 8 November 1973, the trial judges Choor Singh and D. C. D'Cotta ruled in their verdict that both 29-year-old Neoh Bean Chye and 25-year-old Lim Kim Huat were accordingly found guilty of the charge of murdering 42-year-old Chew Liew Tea, after they accepted the prosecution's arguments and rejected the men's defences of accidental shooting or having no intention to kill.

[22][23] Neoh and Lim were reported as among the 17 inmates held on death row at Changi Prison pending their executions as of February 1974, for which the number decreased to 15 by October 1974 while they were appealing their sentences.

[32][33][34] On 27 June 1975, after losing their final death row appeals, both 32-year-old Neoh Bean Chye and 28-year-old Lim Kim Huat were hanged at Changi Prison.

A Buddhist monk, who counselled both Neoh and Lim while they were still on death row, said prayers and authorized their funerals on their behalf after the double hanging of the gunmen.

[37][38] In the aftermath of the men's executions, the trial prosecutor Glenn Knight would become famous for his 1983 prosecution of Adrian Lim, Singapore's most infamous child killer, who was hanged in 1988 for murdering two children for ritual sacrifice,[39][40][41] and became director of the Commercial Affairs Department, but his reputation would be tarnished with his conviction for bribery in 1991.
