"Snakes" -- Catherine and Nick delve into the dangerous world of a Mexican band with a cult-like following, while Warrick and Sofia investigate a man found dead in a handicapped van, on CSI: CRIME SCENE INVESTIGATION, Thursday, Jan. 13 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Richard Lewis directed the episode written by Dustin Lee Abraham.

When a dead baby rattlesnake is found in the throat of a decapitated female head, the CSIs are thrust into the dangerous world of narcocorrido, a Mexican music/lifestyle underworld that glamorizes violence and brutality. Meanwhile, a body is found in the front seat of a handicapped van in a casino parking structure where Sofia and Greg find evidence that the shooter may have been confined to a wheelchair.
