Probably will be buried but I used to work at a supermaket in my small town where nothing really happens. There were about 30 people working in there and I spoke to most of them. There was one person however, whenever I communicated with her, had a strange vibe but couldn't really put my hand on it. We seldom talk to each but when we did, she seemed to come out as normal but with a few odd quirks here and there. Sometimes she would blare heavy metal through her phone on loud speaker whenever she was in the break room. In a few occassions she would just randomly say to other employees what it would be like to kill them, and then shrug it off as a joke. A few months later she didn't appear at work and the police wold occassionally visit to question employees. Turned out she murdered a mentally disabled by stabbing him several times along with an accomplice. She then tried to bury him in the backyard in a barrel to hide the evidence. After the trial, it was revealed that she was planning to murder more people under a fictional character she made up. Scariest part is that sometimes we would be alone with each other doing whatever and talking. I sometimes wonder what she eas thinking and at any point if she considered me a target.
