Cause of death of popular TV actor finally revealed

Alan O'Neil was most famously known for his role as Hugh in Sons of Anarchy. He passed away at the age of 47, and the coroner's report revealed the cause of death.

As reported by TMZ back in June, O'Neill's body was found in his partner's Los Angeles apartment. Authorities investigating his death ruled out foul play.

The cause of death was listed as 'sequelae of chronic ethanol overconsumption,' or alcohol intoxication. O'Neill had a history of alcohol and drug abuse.

He also suffered trauma to the head, believed to be from a fall, as well as coronary artery atherosclerosis. His death has since been ruled as an accident.

His representative, Annette Walsh, told People that O'Neill was a "brilliant funny and kind human being," and added that the world is a darker place without him in it.

"I’ll personally miss knowing Alan isn’t sharing the planet with us any longer, despite the miles between L.A. and Dublin. Alan was only ever a phone call away. May he rest in peace."
