Scott Coppersmith of MyFoxLA.com reports that an autopsy Tuesday on Jimmy "The Rev" Sullivan was inconclusive as to the cause of the AVENGED SEVENFOLD drummer's death.
The Orange County coroner's office ordered "toxicology, microscopic and laboratory tests" to help determine why Sullivan died, according to Jim Amormino, a spokesman for the Sheriff's-Coroner's office.
Sullivan was found dead at the Huntington Beach home on Monday (December 28). He was 28 years old.
"It appeared to be natural causes," said Lt. John Domingo of the Huntington Beach Police Department.
AVENGED SEVENFOLD manager Larry Jacobson remembered Sullivan as "somebody who just had a warmth and an easy smile and a laugh, and he was as smart as they come. You could sit and talk to him about anything."
When Sullivan's loved ones gathered Monday night to share memories of the drummer, the "mood ranged from deep and somber to smiles and laughs as they began to reminisce about the experiences everybody had with him," Jacobson said. "He was a loving son and a loving brother — like no one you'd ever seen, and talented beyond people's perception."
Jacobson added, "He was expressive. He'd tell you how he felt about you — you didn't wonder because he'd put his arm around you. He knew how to tell his friends he loved them."
