I was informed of this at two in the morning, but yesterday, the drummer for Avenged Sevenfold, James Owen Sullivan, a.k.a. The Rev, died in his home.
It was supposedly from natural causes, but the Orange County Coroners office is investigating his death.
He was only 28 years old.
Here's a link to A7X website, with their message:
