My stepson has been the victim of vicious harassment for the last couple of weeks. Multiple text messages (anonymous of course) which started out taunting him with “you don’t know who I am but I see you right now” type stuff, which progressed to, “how about I come up to your apartment “ , finally they became threatening to him and a female supervisor. He thinks it’s a male co-worker. The texts come from multiple numbers (none local). He’s reported things to his employer and law enforcement. Initially he was told nothing could be done unless they knew who it was. My question for you my tech savvy friends is how can I block any “where’s my phone” locator apps this person may have applied to his phone without his knowledge? My stepson is a good guy but in poor health and a little slow mentally. I think someone is messing with him to scare him but my wife is very upset. Any help appreciated. Sorry for the long post!
