T14, E24: A woman signs for a package from RME Delivery, it's empty, and the deliveryman is shot on her doorstep. Detectives Briscoe and Green have a tough time figuring out who sent the empty package, because no ID was required. The victim is John Byrne, so they talk to his widow Adele, who is grief-stricken. She said he was working a lot of overtime, but when they go to John's workplace, he did not work any overtime at all. In fact, he called in sick quite often. The Detectives talk to John's best friend at work and he hints that John had some extracurricular activities on the side. The first lady they talk to says she broke it off because he was cheating on her with other women. They obtain motel footage of John and one of his "dates" in an argument outside of one of the motel rooms.
