Well, I'm NOT glad that their pressing charges. This guy was a member of this forum, a rather well liked and respected member who suffered a recent tragedy. While I'm not a psychologist, I do deal with severe depression every day and this sounds like a pretty classic case to me.
It's a very sad story all around, it's very sad that the animals were suffering and dying, but remember that in the middle of all of this there is also a human being who is suffering as well.
