A woman is sharing letters from some very unusual penpals. Over two decades, Barbara Dickstein and her husband Ritchie corresponded with 100 violent criminals and high-profile murderers. What they wrote might offer some insight into the most notorious serial killers of all time. She shared one letter with Inside Edition that she says came from Charles Manson. Dickstein also says she pretended to be a stripper to lure Night Stalker Richard Ramirez into correspondence.
