I'm sorry...perhaps I'm oversensitive at the moment because my XAH just half-heartedly threatened my parents, but if someone just came out and said "I've had thoughts of killing you", I'd get the heck away from them. Call me crazy, but I'd want to make arrangements to stay elsewhere and I'd be reporting this to a) the police, b) his sponsor and c) his doctor. He may be delusional as well as in recovery.
