IDEA:
A celebrity that's a serial killer and can teleport. Like he goes to the bathroom to shower, then ofc no one is in his room. He showers in Vegas then teleports to Chicago, kills someone, then comes back and keeps showering. He's clean, no one heard the shower delay, everyone assumes he showers that long cause he is famous, no one can prove he was there because he was in a whole different city and was always attended to except when he showers, and his time schedules doesn't match with how long it takes to get there, kill someone and get back, because no one can do all that is the two or three hours he was showering.
