synopsis
At first, all evidence points to suicide when a construction worker plummets 12 stories to his death. Grissom (William L. Petersen), however, flies in the face of conventional wisdom when he surmises that the victim was murdered -- a verdict staunchly opposed by Sheriff Mobley (Glenn Morshower). Meanwhile, Nick (George Eads) and Catherine (Marg Helgenberger) investigate the death of a teenaged epileptic who was undergoing an unorthodox form of therapy with a female psychologist.
