In the episode "Hammer Down", Sheldon displays his anger while interrogating a suspect with Flack. Being a doctor who had lost all of his savings in a scheme, he berated the suspect, who is also a doctor, for using the female victims' organs and body parts for transplanting, among other things for money while Flack watches. "Hammer Down" is part of the CSI trilogy in which Dr. Raymond Langston (played by Laurence Fishburne), of the Las Vegas Crime Lab investigates the kidnapping of a young woman in Miami, who was later believed to have been taken from Las Vegas.
