Say hello to Matthew. He claimed he had come here for the census... Another one of those goddamn government spies.
Matthew was one of the victims of Adrian Baker. He went to the doctor's house, claiming he was there to record the survey on population (a census). However, he was actually sent there to spy on Adrian, so the doctor used his power drill to practice surgery on him. His body can be found slumped against the wall in the basement if Madison Paige ends up there.
