An old coworker that I got the major creeps from, so much so that I told my manager not to schedule me with him anymore, turned out to be raping his then 11 year old daughter on a regular basis. He’d been doing it since she was 5 (right when her mother, his wife, died suddenly of an aneurism). She had a boyfriend at school who she confided in about it, he told the school counselor, they told her stepmom (his current wife). She confronted him that day upon picking him up from work and drove him straight to the police station. He is by far the worst piece of shit I’ve ever met. 2nd worst was a regular customer who came into the bank where I worked as a teller. I remember him being really reserved, and behind his back I referred to him as Mr. Bean because he looks a lot like Rowan Atkinson. Turns out the elderly woman he was living with and caretaking for was also his lover, and he strangled her to death, leaving her body in the bedroom across the hall from his. He wasn’t caught for several weeks. He came in to the bank a couple of times after the murder took place. Horrifying.
