Martin Feiser

Martin Feiser was a convicted and executed serial killer and serial proxy killer through Seth Elliot, appearing in Ceremony of Innocence in Profiler.

Modus Operandi
Feiser targeted middle-aged Caucasian men he'd troll for on the streets. He killed them with several shots to their bodies, often shooting their knees out to incapacitate them. They were found in alleyways and off the sides of roads, his signature laying them on their sides with their arms and hands together, folded as if they were "praying". When he "killed" Elliot, he pulled his life support, not realizing he was already dead. When he communicated with Elliot to conduct him in his copycat murders he had him do, they communicated with pictures of chess positions and moves, the notations being their coded communications.
