S3E6 Dog Proof

At a construction site in Indiana, the bodies of three workers are discovered, each shot dead. As detectives sift through the limited list of suspects, they uncover a significant piece of evidence: one of the assailants left behind a trace of dog waste on his shoe during the incident. If the detectives can track down those shoes, they may be able to identify the murderer.
