Let It Bleed (S09E04)

Formerly called "Scales," a young woman who happens to be the daughter of a Colombian drug lord, is killed and dumped behind a club. At first, the team thinks that the club owner, played by Jason Lewis is the murderer, but things become complicated when they find the girl has blood from three different people in her system at the time of death. It turns out she was trying to find cocaine, and she snorted atripene -- which killed her -- and the men who gave her the atripene tried to give her a home-made blood transfusion. (CBS TV Network)
