Asa Emory is a methodical and ruthless serial killer who views his victims not as people, but as specimens to be collected. Operating with the precision of an entomologist, he transforms ordinary homes into lethal labyrinths of intricate, spring-loaded traps.

Behind his silent, calculating background as a pest control worker on his off-work days lies a predatory obsession with entrapment and preservation. He doesn't just seek to end life; he seeks to curate it, claiming a single "prize" from every massacre to keep in a trunk for further torment and exposure.
