The father of a 16-year-old San Francisco boy who was found shot to death in a gasoline-soaked room says he doesn't believe another teen's claim that the killing was accidental.
The San Francisco Chronicle says Zhi Xiang Zeng spoke Thursday at a news conference held to announce a relief fund drive for the family.
His son, Andy Zeng, was killed on April 10.
A 15-year-old friend told investigators that Zeng was accidentally shot as the two played with a .22-caliber handgun. He's been charged as a juvenile with murder and attempted arson.
Police contend that after the shooting, Zeng's friend and 18-year-old Jimmy Lei tried to burn up the evidence but their matches were wet. Lei has pleaded not guilty to attempted arson.
