08E11 - Bull

Grissom and Willows investigate the death of a rodeo star found in middle of the bull ring. He was at the end of his career but was a champion bull rider. When, a few hours after his death they discover the body of a prostitute who had been staying in his hotel room, they're sure they have a double homicide. The trick, as always, is to try and determine who killed who. Although the woman had been run over by her the rodeo star's truck, the pathologist determines that he died before she did. So determining just who was driving the pickup truck - and the reason they were in a rush - provides the solution to both deaths.
