SAN FRANCISCO, Dec. 11 (Xinhua) -- A court in San Francisco, a major multi-ethnic city in California on the U.S. west coast, found on Monday a man guilty of killing all five family members in a grizzly homicide in 2012, local TV KRON 4 reported.
The jury of the San Francisco Superior Court decided that the 41-year-old man, identified as Binh Thai Luc, an undocumented Vietnamese immigrant, was guilty of killing three women and two men, all family members, at a home near City College of San Francisco on March 12, 2012.
The grandparents, their daughter, son-and-daughter-in-law were all bludgeoned to death with a hammer.
The case has been called one of the most gruesome in San Francisco's history, the TV report said.
Luc was convicted of five counts of first-degree murder as well as attempted robbery and burglary charges.
He had worked as a plumber and was a longtime friend of Vincent Lei, one of the victims.
Luc was convicted of robbery and assault in San Jose back in 1998. After he was released from state prison, the U.S. immigration authorities had attempted to deport him back to his native country Vietnam, but rejected by Vietnam, according to the report.
