A fight between rival gangs led to the death of a 20-year-old man at a festival in southwest Fresno in May, according to search warrant documents made public Friday in Fresno County Superior Court.
Yer Yang was beaten to death about 1:35 p.m. May 29 at the Fresno Regional Sport Complex on West Jensen Avenue, where families were attending the Lao Family Water Festival, police said.
Yang was a founding member of the Purple Brothers street gang, according to a court affidavit by Fresno police detective Todd Fraizer.
He and about a dozen other Purple Brothers members and associates were at the festival when they were confronted by members of the Men of Destruction street gang.
A fight broke out, and rival gang members cornered Yang behind a wall and kicked and beat him, knocking him unconscious, the sworn affidavit said.
The gang members ran when a city employee said she was calling police.
Yang was later pronounced dead at Community Regional Medical Center. A coroner's report said he died of blunt force trauma to his head.
Fraizer wrote the affidavit to get a warrant to search Yang's MySpace account on the Internet.
The affidavit said Yang and a member of the rival gang began exchanging threats on the Internet around May 10.
Two weeks after Yang's death, the rival mentioned the beating on the social-networking Web site, Fraizer said.
