Authorities investigating the death of DJ AM have found that he had eight undigested OxyContin pills in his stomach and a ninth in his mouth, a law enforcement source tells PEOPLE.
The finding suggests that DJ AM -- real name Adam Goldstein -- swallowed the powerful painkillers quickly. "He wanted to die," says the source, who says the suicide theory is supported by the pills and other evidence. "He was going unconscious when he took the last one. He didn't even swallow it."
