General Hospital Actor Johnny Wactor’s Cause of Death Revealed

(People) – New details have been released in the death of General Hospital actor Johnny Wactor.

The Los Angeles County Medical Examiner-Coroner has determined that the actor died from a gunshot wound to the chest. His manner of death is listed as a homicide.

Wactor was fatally shot in the early morning hours of May 25 when he came upon three armed car thieves who were attempting to steal his catalytic converter from his vehicle, his brother Grant Wactor told PEOPLE.

Grant said his brother — who was working as a bartender — and a female co-worker were walking to their vehicles after their shift around 3:25 a.m. when the shooting happened.

Grant said the colleagues were approaching their vehicles when Wactor noticed his car “was jacked up or lifted in some way. He thought he was being towed.”

Grant said his brother soon realized “they were definitely not tow truck people.”
