My money's on attempted suicide being the reason for hospitalization.
This is all pretty sad and pathetic, as per usual for most mainstream-news-making furry activity. It is pretty funny how they're trying to spin the furmeets from 'a gathering of perverts' to 'a group of friends who saved [the victim]'.
At the very least it's nice to see in this case, and in one of the recent dogfucking cases, some furries had common sense and conscience, and reported abuse crimes. Maybe they can integrate that as a fetish somehow.
