Kill Switch

S5, E23: After a suspected carjacker is murdered, the CSIs learn that the victim may have been involved in drug smuggling off the shores of Miami. Ryan identified the suspect during a segment on his news program and soon after a self-proclaimed vigilante killed the suspect. But when the evidence doesn't add up, the CSIs discover the vigilante only wanted the credit and did not kill the "carjacker." Further investigation leads the CSIs to a cigarette boat the victim used to smuggle drugs to a drug lord who caught the victim swindling and wanted him to pay.
