I'm sorry if this isn't the right place to ask this, I really just don't know shit about online stuff lmao. My father has an employee who has had a very mentally ill husband for a while. One year ago, the two got a divorce, and the man become even worse, and bought a gun. His ex wife (my father's employee) had to go to the hospital a few months ago, and listed my father as one of her emergency contacts, which she has to do because my father is the only manager in her area and her job requires her to do that. Her insane husband saw that, and thought the two were having an affair and that's why she divorced him. This morning, they got in a big fight, and he looked my father up online and immediately found his address. Now, he's going there to kill him. Luckily he already left and is safe. How do I get his info offline and stop this from happening again? Police are fucking idiots of course, so even if the guy does show up to the house they won't do anything. Thank you in advance, again, I'm sorry if this is the wrong place to ask this.
UPDATE: the man turned himself into the police and has been placed under a 72 hour psychiatric hold. Thank you to everyone who helped.
