My wife had this problem in the late ‘90s. She was a sportscaster on a couple of popular networks and ended up with a stalker. He would send threatening letters to me telling me he was going to kill me. It’s when my wife and I bought our first handguns.
Ultimately the FBI needed to get involved. He spent several years in prison. We never heard from him again after that.
It can be quite frightening to go through that.
You should keep track. Seriously.
A very close friend was murdered decades ago by the sublet roomy, rolled him up in a rug and stuck him in a dumpster. An aluminum can collector found them two days later.
Went to court, went to jail, and the victims family, myself and others included keep track of that scumbag.
It was totally unexpected.
The murderer was a practicing architect. It’s not like he was some dirt ball out of nowhere. A letter writing chain was pulled together when parole considerations were announced.
