All the young murderers detained at Her Majesty's pleasure are free after the last underage killer was released in December, marking the end of an issue left over from the colonial era.
Lam King-wa, who was convicted of murder after a gang fight in May 1989, was released from Ma Po Ping Prison on Lantau four months ago after having served two-thirds of his fixed sentence of 27 years. He was 16 at the time of the murder.
He is the last of the 14 young murderers detained at the Chief Executive's discretion - an indefinite sentence known before 1997 as 'at Her Majesty's pleasure' - who have won freedom since the handover.
Cheung Yau-hang, one of the five killers involved in the horrific Braemar Hill killings in April 1985, was freed at the end of 2007.
Legislator Leung Yiu-chung, who launched a campaign before the handover to fight for a definite sentence for prisoners convicted of murder when they were under 18, said Mr Cheung had been hired as an inspection worker at a public utility.
Mr Cheung and Won Sam-lung, both 16 at the time of the murders of Island School students Nicola Myers and Kenneth McBride, were sentenced in 1987 to be detained at Her Majesty's pleasure, and were held at the Chief Executive's discretion after the handover.
