From Momma Bear's (Chris's mom's) status message tonight:
Well it looks like Chris's suicide may indeed have been an accident. You can definitely tell he slipped and fell, there is no denying that. I do not believe the Chris we all knew and loved would think or believe he did it on purpose. Unfortunately when you play dangerous games (like Russian Roulette) you sometimes lose. Chris thought Lacey [his ex-girlfriend, probably the main person responsible for the state he was in in the first place] was on her way over. But because he had been drinking he was not thinking.
