James Owen Sullivan (February 9, 1981 – December 28, 2009), more commonly known by his stage name The Rev (shortened version of The Reverend Tholomew Plague), was an American musician and songwriter, best known as the drummer and founding member for the American heavy metal band Avenged Sevenfold. The Rev was critically acclaimed for his work on the Avenged Sevenfold albums Waking the Fallen and City of Evil. He was also the lead vocalist/pianist in Pinkly Smooth, a side project where he was known by the name Rathead, with fellow Avenged Sevenfold member and childhood best friend, guitarist Synyster Gates, and he was the drummer for Suburban Legends from 1998 to 1999. The Rev was found dead in his Huntington Beach home on December 28, 2009. Police ruled out foul play and noted his death appeared to be from natural causes. An autopsy performed on December 30, 2009 was inconclusive, but toxicology results revealed to the public in June that he died from an overdose of Oxycodone (Percocet), oxymorphone (a metabolite of oxycodone), diazepam (Valium), nordiazepam (a metabolite of diazepam) and alcohol. The coroner noted cardiomegaly (enlarged heart) as a "significant condition" that may have played a role in Sullivan's death.
