the cleaner

A specialized person who removes incriminating evidence from a crimescene (usually one involving murder) in order to make the legal consequences of the crime go away. Cleaners will get rid of evidence like bodies, blood, weapons, fingerprints, and even witnesses in order to hide the proof or notion of the crime -- or, they will 'dress up' the crimescene to mislead authorities. For example, they could make it appear like a break-in gone bad, an act of self defense, a fire, etc.
