My first thoughts were accidental drug overdose or suicide. I he was about to lose his home according to Fox. That makes me wonder.
I had a great friend who, like him, was a brilliant artist and childlike person. She committed suicide when she turned 50. She simply could not handle that she was aging. Her face was getting lines and her cheeks were sagging, and she had not achieved inner peace after years of psychotherapy. What a shame she didn't know Jesus; and the same with him -- If his conversion to Islam is to be believed, I pity him all the more.
