I have met a few infamous Killers.
1 John Dupont(Hollywood made a movie), He was creepy and gave this eerie feeling around him
2 Richard(Ricky) Plotts ,He was always an asshole and the last time I saw him he stole from my buddy.
I know his family well and grew up in the same hood as him off n on. He made national news when he Killed my GF's friend Theresa at Fitzgerald Mercy Hosp in PA when DR Silverman shot him to stop him. Ricky was always a pos.
3 John Wrightly , he killed 2 young ppl,1 was my buddys fiancee.. he was always an asshole, he was killed in prison, good
4 Stephen Shappell(TV Movie made). he was a nice kid, tricked by a ho. His aunt was my babysitter 50 yrs ago when I was a kids
I know members of the Capano family well too, I did not know Tom personally but met people directly involved many times (made a mini series out of it)
