The Truth Is out There

During a rave party, the body of a Petty Officer falls through the ceiling. Preliminary investigation suggests that the Petty Officer was killed in the nearby parking lot, and was dressed after his death. Upon checking the victim's room, evidence surfaces that he might been taking financial bribes or someone else may have been blackmailing him. Gibbs suspects the victim's co-workers of involvement in the death when their separate versions of events are too consistent. Forensic evidence links them to the scene, and they eventually confess that the death was a prank gone wrong, but Gibbs still believes that there's more to the case than meets the eye and also that one of the victim's co-workers actually murdered the Petty Officer.
