I don’t know about you, but I am fascinated by murderers. The idea that a human could do something so heinous is captivating to those of us who have never had the urge to hurt someone.

Having watched an abundance of documentaries profiling serial killers, it’s easy to believe that all criminals exhibit “red flag” signs which can highlight their sinister intentions before they act upon them. Whether it be a penchant for inflicting pain upon other children in the playground or a taste for torturing animals, we always assume that killers fit a particular profile.

But that isn’t always necessarily the case as the following Reddit users all revealed when they shared stories about interactions they’d had with convicted murderers…

1. Workshy

“One of my bar patrons worked with Gary Ridgeway the Green River Killer. Apparently Gary would sit and read his bible at work, was quiet and anti-social. When the cops started asking around work the guys would tease him saying don’t go killing any hookers this weekend, and whatnot. When Gary finally got arrested my customer took over his job and got assigned to his desk which had Gary etched into it.”

2. Buddy with Bundy

“My former co-worker knew Ted Bundy from a volunteer group in Washington state. Said that when he was around other people, he was handsome, charming and very polite. He’d offer to help if you needed it. Then she said towards the end of his time at the volunteer group he’d become more distant socially. She said he once offered her a ride home afterward, but that she declined cause she was being picked up by her parents that night. She didn’t know WHAT kind of killer he was until years later. She always said ‘she missed the worst ride of her life that night’.”

3. Should have seen it coming

“My cousin went to school with Timothy McVeigh [McVeigh was an American domestic terrorist, responsible for the 1995 Oklahoma City bombing, the second deadliest act of terrorism in the US after the September 11 attacks. He was ]. She says he was a really creepy loner who would talk about conspiracy theories all the time.”
