Well hopefully OP or the suicidal guy was bluffing, or someone called the police in time. It's been ten hours so by now whatever happened has happened.
And in case he doesn't update the topic, I'd say it's safe to say that either the topic is fake, or he didn't make it.
I think we've plenty established how the sensible thing to do was call the police, but it's too late for that now. So can we get off the topic? It isn't going to help any
