Los Angeles authorities say a 16-year-old fatally stabbed his teenage friend, then joined a search party and ultimately led them to the victim's body.
Sheriff's Lt. John Corina says the suspect had been close friends with the victim. Coroner's officials identified the slain teen as 17-year-old Jeremy Sanchez.
Corina says detectives are still trying to identify a motive for the killing.
He says the suspect, whose name hasn't been released, stabbed Sanchez multiple times and left his body in a wooded area near a riverbed in the Los Angeles suburb of South El Monte.
When the victim didn't show up for school, his father put together a search party with the boy's friends. The suspect and another friend found Sanchez's body Wednesday.
