Mike ScacciaA medical examiner has determined that guitarist Mike Scaccia died of a sudden heart attack. As reported previously, the beloved guitarist, who played with the bands Ministry and Rigor Mortis, died after collapsing onstage during a performance celebrating Rigor Mortis frontman Bruce Corbitt’s 50th birthday. Yesterday, on his Facebook page, Corbitt posted a touching remembrance of his time with Scaccia. “You know I keep thinking about all of this," Corbitt wrote. "Why this happened the way it did. Why it happened at all. What if I wouldn't have asked them to play for my birthday show? But mainly, I keep thinking of the conversations I had with Mike in recent years. Each close friendship is different... you cherish them all. I talked about things with Mike that I couldn't with some other close friends.

"So what I do know is how happy Mike was at this point in his life,” Corbitt added. “He loved his wife and kids so much. He talked about them all the time. He loved his bandmates from his different bands. He loved his friends... past and present. He loved his job working for Gibson Guitars. So that gives me some kind of comfort just knowing he was enjoying his time on earth until the very end."

Scaccia is survived by his wife Jenny and four children. A memorial has been scheduled for Sunday, December 30 at 3 p.m., at Aristide Event Center in Mansfield, Texas. The event is open to the public.
