The episode details the investigation into the death of Jeffrey Gebhardt, who was found with multiple stab wounds in a dry lake bed. Initially, his friend David Smith was considered a suspect, but DNA evidence cleared him. The medical examiner ruled the death a suicide, citing the nature of the wounds and lack of struggle, despite the family's strong objections and belief in foul play. Years later, a Florida State CSI team reviewed the case and also concluded it was suicide, though they initially suspected homicide based on photographic evidence. The case was ultimately closed as a suicide.
