He is a 19 year old dropout college student who has been stalking her sister for at least a year now. He has wrote obscenities on her facebook, showed up to their house multiple times, subtly threatened her, came to their house and egged her cars, recently over 4th of july week he came by and smashed their mailbox, bashed the windows of one of their cars and slashed their trampoline with a knife. He recently posted on facebook that he was going to kill himself so he is very unstable. I am planning on staying at their house with my gun until this blows over. I am also going to put up a trail cam on their tree for evidence. He was jailed for a while and was released yesterday. I am worried he will come over again and try to hurt someone. The sister has a restraining order against him but I doubt that would stop him. If he shows up on the property is it fair game for me to do as I please to him legally? Any advice is greatly appreciated.
Im in MN by the way.
