ABBY: I used the victim's measurements and the location of his injuries to determine the height of the vehicle based on point of impact. CARTER: He knew it was a prank? DUCKY: We know someone dressed him after he was killed, based on the condition of his clothes and the bloodstain patterns. GIBBS: A little too consistent. GIBBS: Good worker? GIBBS: Is that true, Petty Officer Wong? His fall through the ceiling only added insult to injury. How did Petty Officer Gordon end up in the basement ceiling? KATE: Evidence. KATE: We think that when Gordon found out that Nutter was taking kickbacks, he blackmailed him. MORGAN: It was an accident. Or maybe they just wanted payback. TONY: Kate, have you ever been in a men's room before? TONY: Their stories are pretty consistent. TONY: We know Gordon was purposely run down in the parking lot, probably died from a fractured skull, and somebody hid his body in the warehouse ceiling. That must have been some girl, Petty Officer Wong. WONG'S CAR - FLASHBACK

A: Forensic evidence; Q: What links the coworkers to the scene? Summary: During a rave party, the body of a petty officer falls through the basement 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 have 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 their coworker's death was a result of a prank gone wrong. However, Gibbs believes that the petty officer's death was more than just an accident.
