Nguyen Ngoc Giau, 43, was found guilty of the charge on Tuesday, with Justice Dedar Singh Gill saying he was satisfied that the elements of the charge had been established beyond a reasonable doubt.

“I also find that the accused has not succeeded in establishing, on a balance of probabilities, either the defence of intoxication or the defence of sudden fight,” he added.

Nguyen had stabbed Cho Wang Keung, 51, along the common corridor on the fifth floor of Block 562, Ang Mo Kio Avenue 3, on July 15, 2021.

Cho was a jewellery assembler and landlord who owned a three-room flat at the public housing block.

Nguyen, who is a Singapore permanent resident, moved in as a tenant in July 2020 but began sharing a bedroom with Cho after they became romantically involved.
