There was a lot of stray contact DNA in the junction, caused by so many humans coming through here and touching stuff. (Humans touch stuff all the time, I wish they wouldn’t.) But the presences and absences of contact DNA on the body told an odd story. I said, "The perpetrator used some kind of cleaning field after the attack."
