[Deputy Chief Pat] Gannon indicated it was common knowledge there could be trouble, given that such events are notorious for illicit drug use.

Officials at the Los Angeles Memorial Coliseum have initiated a temporary ban on raves.

Tuesday's death was the latest in a string of high-profile problems at raves at public venues. Earlier this year, at least 18 drug overdoses tied to ecstasy were reported at a New Year's Eve rave at the Los Angeles Sports Arena, next to the Coliseum. And two men died of suspected drug overdoses during a Memorial Day weekend rave at the Cow Palace in Daly City, south of San Francisco.
