LeRoi Moore of the Dave Matthew's Band is dead at age 45? ATV accident? Your thoughts?

Dude, what is going on? People are leaving this earth left and right. Heath Ledger, Bernie Mac, Isaac Hays and now LeRoi Moore of the DMB. He was the band's saxophone player with the signature sound. Man that sucks that he's gone. RIP LeRoi. You'll be missed. : (
