Avenged Sevenfold drummer Jimmy "The Rev" Sullivan died on December 28, 2009 from an accidental overdose of prescription drugs and alcohol, Orange County Deputy Coroner Mitchell Sigal told Rolling Stone. Toxicology reports indicate that Sullivan suffered "acute polydrug intoxication due to combined effects of Oxycodone, Oxymorphone, Diazepam/Nordiazepam and ethanol."

Oxycodone is painkiller that substitutes for Codeine, Oxymorphone is a painkiller similar to Morphine, Diazepam/Nordiazepam are anxiety medications and ethanol is the intoxicant in alcohol. Actor Heath Ledger similarly died from acute polydrug intoxication on January 22, 2008. Sigal added that Sullivan also had cardiomegaly (an enlarged heart), which was marked in the coroner's report as a "significant condition" that may have played a role in the drummer's death. The Coroner's Department conducted "five or six" different tests to verify the cause of death, Sigal added.

"To all of us who loved Jimmy, the only thing relevant about December 28 is that is the night we lost, too soon, a son, brother, friend and one of the most talented artists in the world," the band's manager Larry Jacobson tells Rolling Stone. "Every day, his parents and sisters, and his brothers in Avenged Sevenfold smile at the many memories they have of Jimmy and his fans around the world revel in the musical legacy he left them."

Sullivan, 28, died at his home in Huntington Beach, California. He was buried in a private ceremony on January 6th. Avenged Sevenfold guitarist Synyster Gates delivered a eulogy at the cemetery in front of the band, Sullivan's wife and family, ex-Pantera drummer Vinnie Paul, Bullet For My Valentine frontman Matt Tuck and members of Buckcherry and My Chemical Romance. -rollingstone.com
