There’s much discussion and debate online about a connection between OCD and serial killers. Since killing is an obsession or compulsion with them, it’s not hard to jump to conclusions. Of course, most people with OCD aren’t murders, but it’s something to consider.
When I worked the kosher deli at Winn Dixie in South Florida, we had one of these guys as a regular customer. He was utterly harmless, except it took a couple of hours to serve him, and nobody had the patience to do it except me. I could see him becoming a serial killer under the wrong conditions, but right then, he was just a soft-spoken, gentle, glove-wearing nut case.
Could be that Paddock was similar, but also with a pathological hatred of country/western music. Maybe he was molested by a baby-sitter who played Hee Haw on TV real loud to drown out his screams.
There haven’t been any reports that this is a life long condition for him. A relative had had cancer treatments and became allergic to substances they never had a problem with in the past. He was at the age where multiple types cancers are a possibility . If he had medical problems, Hippa rules would probably slow any release of that info..
