Murder of Hor Koon Seng

On 2 April 1974, inside an army camp at Singapore's Portsdown Road, 19-year-old National Serviceman Liew Ah Chiew (刘亚超 Líu Yàchāo; also spelt Liew Ah Chew or Liew Ah Choy) used a rifle to shoot his platoon commander, 21-year-old 2nd Lieutenant Hor Koon Seng (何君成 Hé Jūnchēng) of the Singapore Armed Forces (SAF), resulting in Hor dying from a gunshot wound to his chest. Liew was arrested on the same day and was charged with murdering Lieutenant Hor, whom he killed due to his dissatisfaction and anger against Lieutenant Hor for wanting to bring forward disciplinary charges against him. Despite putting up a defence of diminished responsibility, Liew was found guilty of murder and sentenced to death on 25 October 1974. Liew's death sentence was upheld and finalized despite his appeals, and he was hanged on 28 November 1975. Provided by Wikipedia
