Man Questioned in Double Slaying

A Temple City man was questioned Thursday in the slaying of an Irvine piano teacher and an award-winning pianist who were found stabbed to death in their upscale condominium earlier this week.

Guy Thomas Whitney, 60, a popular piano instructor, and Lawrence Wong, 51, a renowned pianist, were attacked with a knife about 9:30 p.m. Monday in their Solana home overlooking the Rancho San Joaquin Golf Course. Their bodies were found the following day, sending shock waves through a community where violence is rare.

Friends told detectives that Whitney had complained that a former boyfriend, Vincent Choy Cheung, 36, had been stalking him in recent weeks, police said. Cheung, who described himself as a student and actor, was arrested Thursday on an outstanding warrant unrelated to the killings and then questioned about the deaths, said Irvine Police Lt. Sam Allevato.

“At this time, Mr. Cheung remains a suspect only, and has not been charged with the murders,” Allevato said, adding that investigators planned to question others who knew the victims.

Authorities said Cheung apparently dated Whitney until March. Police searched Cheung’s home and car, Allevato said.

Police said the victims had been living together since Wong moved to Orange County about five weeks ago.
