CSI: Crime Scene Investigation

Grissom and crew are called in after high roller Tony Braun, a known drug addict, is found dead in his house by a gardener.

But further examination of the corpse reveals that Braun had been restrained at some point with duct tape, leading Grissom to believe that the victim was forced to ingest lethal amounts of heroin and, perhaps, other drugs.
