Suicide. A knife wound? Ouch. I don't think he had any children, or I hope not.
He came out of the grunge movement of the early '90s as a member of Heatmiser. As a solo artist, he was not "grungy" though. I think he got the most mainstream recognition for having a song on the soundtrack of Good Will Hunting ("Miss Misery").
He was a very gifted songwriter and had a beautiful voice, too.
