All sorts of things going on with him over the past few years, none of them good. Treatment for a long-time "addiction" to weed and other rumored drug addictions as well as a tracheotomy. Rumors that he was on a steep descent. When you die "peacefully" at home, it's usually not a sudden illness. We'll see in the coming days. Sad. He was tremendously talented.
Sas, everyone ultimately dies from heart failure. There has to be an underlying cause. GM abused coke, booze and weed together for years. When it all comes out, I'll be dollars to donuts that's what caused his death at age 53.
