The Perfect Murder (2014)

When a crime scene throws suspicion in multiple directions, investigators may have a perfect murder on their hands. Ingenious killers are every detective's worst nightmare, as the crimes they commit are full of leads that become dead ends, and multiple suspects are ultimately discarded. But just when a murderer thinks he or she has successfully gotten away with it, one small clue leads to another and a cold case suddenly turns hot. "The Perfect Murder" follows actual cases and uses stylized re-enactments depicting detectives slowly putting the pieces together to complete intricate puzzles.
