A Sinking Feeling: Upon arrival, River told her there were people playing music and they would go in. Mathis immediately sensed something was wrong. She stated that she knew he was high, but not on heroin. “I didn't see anyone doing drugs but he was high in a way that made me feel uncomfortable,” she recalled.

The Tragic Turn: While Mathis was in the bathroom, River Phoenix injected the speedball—a lethal mix of heroin and cocaine—that would cause his overdose. She did not witness the drug use itself.

The Collapse: When she emerged, the situation had escalated. River was being escorted out of the club. In the street, he collapsed and began having seizures. Mathis watched in horror as his younger brother, Joaquin Phoenix (then 19), made the frantic 911 call that would become tragically famous.
