THE family of Elaine Luk Yee-ling, the Baptist College student who died after being drugged with chloroform and sexually assaulted, is to ask the courts to give her killers tougher jail sentences. Businessman Hon Leung-fong and his lover, Phoebe Wong Yim-ping, denied murdering Luk at the Royal Park Hotel in Sha Tin on July 24 last year during a court hearing earlier this month, but admitted manslaughter. Last week, Hon, 33, was sentenced to 81/2 years in prison and Wong, 28, was sentenced to seven years. But with good behaviour both could have their terms reduced by three years. The Luk family's lawyer, Albert Ho Chun-yan, said he would write to the Attorney-General this week to ask for a tougher sentence. Karen Luk, the victim's elder sister, said she was ''very afraid some of our family members'' would seek out the defendants on their release. ''We are all very, very angry. I really don't know what they will do if the appeal is rejected,'' she said. ''It seems to me that the judge considered the guilty pleas of the defendants more important than the harm done to [Elaine] and her family.'' Dick Luk, the victim's father, said while nothing could compensate for the loss of his daughter, the jail terms should be longer. ''We hoped our life could start all over again after they [Hon and Wong] received the punishment they deserved. But such a wish has not been granted,'' he said. ''Even if they are sentenced to 20 years in jail it is not enough.'' The family moved recently in a bid to put the tragedy behind it. ''Yee-ling was a quiet, good, and hardworking girl,'' Miss Luk said. ''She was kind to everybody; we all miss her very much.''
