Counselors at Thurgood Marshall Academic High School are organizing grief sessions for friends of 16-year-old Andy Zeng, who was found murdered over the weekend, according to media outlets.
Police found Zeng's body with a gunshot wound and doused in gasoline at about 4:30 a.m. on Sunday. They first believed it was a suicide, but quickly determined the boy had been killed. It is the city's 20th homicide this year.
Police have arrested four juveniles in connection with the homicide. They are still looking for one more suspect.
Zeng's body was found at a two-story home on the 2100 block of Quesada Avenue in the Silver Terrace neighborhood. Zeng did not live there, police said.
Police arrested a 15-year-old boy on suspicion of murder. Three others boys -- aged 15, 16, and 17 -- were arrested on charges of conspiracy and attempted arson.
Lieutenant Troy Dangerfield told SF Weekly this morning that he did not know a motive, nor did he have any more details on the case.
