Evil online?

I watch investigation discovery a lot. I was just watching evil online. God its so creepy. This one was about this guy who stalked a teacher, and he told her a bunch of lies, and they met on a beach in florida, and at first they were dating like for 8 months, and then he wrote a ton of post it notes and put them all over her house to say this is too hard and I cant do this and , dont look for me etc etc. but then after 2 years he contacted her again, and he would not give up, kept watching her, showing up where she was etc. anyway he had told her his mom and dad died when he was 12, and that he was adopted, that they’d died in a car crash. turns out he wasnt using his real name at all, and that he’d actually murdered his parents and his 10 year old brother when he was 14. the girl he was stalking went to the police with this info, but all she was able to get was a restraining order, and the police had no power to arrest him, not unless he hurt her in some way, even though she was scared for her life, they could do nothing. anyway, he kept sending horrific emails, evil ones, that threatened this girl, and in the end the police did trace him, and luckily for her they caught him just in time, as he was in georgia when they caught him, in a motel, but he was on his way to her school where she taught second grade, with a gun. god knows what would have happened if she didnt find out about his past, and if the police didnt trace him. she probably wouldnt have been around to live to tell the tale.

I find shows like this so interesting, but my god, it also scares me half to death!
