I have a narcissistic ex, whom quit his job and got hired on as a temp at my place of employment the week I broke up with him. On 2 separate occasions and on 2 different cars I've had to file police reports for vandalism due to them being keyed. What are your suggestions for the best way to catch him in the act? I've been told to put trail cams in my car and right.  that seems to be the best option.  Also, nothing has happened at work to have anything done to either terminate him or anything, but I do feel very uncomfortable with him working there and they've offered him a full time position so I will have to see him every day. It would be slightly different if it was a different shift but he's on the same shift as me.

Quick summary of breakup; had to call cops because I found him in the bathroom with a knife, my first car was keyed, had to move per cop request for my own safety, so I have moved to a location he does not know since he's not from here, got a new car to help with any possible stalking, new car was keyed, he is blocked on every possible thing out there, phone, Facebook, all social media.... during our relationship he did rape me but I haven't confronted him about it, he's a lot bigger than me so that intimidates me.

We have been broken up for 6 months and my 2nd car was keyed the beginning of this month possibly outside my new/current boyfriends house.
