Very sad news indeed ... Jezebel may you rest in peace.
As smc stated (and Bob's site as well) who knows what exact circumstances led to this decision. It does bring to mind one photo shoot she did with a damaged eye, after having been in a fight the night before.
When I saw those photos it crossed my mind that Jezebel must have been going through some issues and that hopefully she could work them out. It's a terrible shame that ultimately she could not resolve the challenges she faced.
Jezebel, you will be missed!
