Killing Spree

S2, E8: In Little Rock, Detective Chuck Ray is called to a scene where one man has been shot in the hand while another man lies dying outside of his apartment with a gunshot wound to the abdomen. Shell casings and clues point to a serial robber that police have been tracking. But the serial robber doesn't usually kill his victims. Could this be the same guy? And is he getting even more dangerous? When a shooting takes the life of another innocent victim weeks later, and the patterns seem to match, Ray knows he and the team must work quickly to get this serial killer off the streets right away.
