SEATTLE -- King County Prosecutor Norm Maleng told a parole hearing that he'd like to see more prison time -- not less -- for Tony Ng, who was convicted of robbery for his role in the slayings of 13 people in Seattle's 1983 Chinatown Massacre.

A state sentencing review board met Wednesday today to consider whether to parole Ng. The board will meet with Ng in prison before determining how much time remains on his sentence.

Families of the victims also told the Washington State Indeterminate Sentence Review Board they oppose Ng's release.

"One that day, 23 years ago, I was left to be the only man in my house," said Jason Louis, whose stepfather was killed.

Former Seattle Police Chief Patrick Fitzsimons told the board the killing was the worst crime he saw in his career, including time he served in New York City.

Two co-defendants convicted of aggravated murder for the killings at the Wah Mee gambling club -- Benjamin Ng, no relation to Tony Ng, and Kwan Fai "Willie" Mak -- are serving life sentences, without the chance of parole.
