HUNTINGTON BEACH -- An autopsy on Jimmy "The Rev" Sullivan, the drummer for the hard rock band Avenged Sevenfold was inconclusive, according to the Orange County coroner's office, and more tests will be performed to determine the cause of death.

Sullivan, 28, was found unresponsive at his Huntington Beach home Monday, authorities said, adding it appeared he died of natural causes and there were no signs of foul play.

The coroner has ordered toxicology tests on Sullivan's body, the results of which could take several weeks.

Avenged Sevenfold issued a statement on its Web site Monday.

"It is with great sadness and heavy hearts that we tell you of the passing today of Jimmy `The Rev' Sullivan," the statement said.

"Jimmy was not only one of the world's best drummers, but more importantly he was our best friend and brother. Our thoughts and prayers go out to Jimmy's family and we hope you will respect their privacy during this difficult time."

Sullivan is survived by his wife, Leana MacFadden.

By Tuesday morning, a Facebook page for Avenged Sevenfold had received more than 4,900 comments in response to a posting about Sullivan's death.
