If you killed someone.... What would you do with the body ?!
Depends on the senerio.
A Science Fiction, you could reverse the polarity on the teleport & just dematerialize the body.
A Mystery, there could be a mysterious Gas leak that affected everyone's else's memory. Don't bother about hiding the body, just set it up so everyone could be considered the murderer.
A Spiritual - suggest some mystical deity swoops down & takes everyone with them. Loool
