The contents of the ash tray used by the subject and a towel removed from the rear of the seat he allegedly occupied, were submitted to the FBI Laboratory on 12/7/71, by the Las Vegas Division.

The Laboratory, by communication dated 12/13/71, advised that no latent fingerprints had been developed as a result of examining the contents of the ash tray.

The Laboratory advised however, that the ash tray contained eight cigarette butts, seven of which are Raleigh 85mm filter tipped cigarettes. The eighth cigarette butt has the same design and composition as Raleigh 85mm cigarettes and accordingly, probably is a Raleigh 85mm filter tipped cigarette. This type of cigarette is sold in a "soft pack."

The FBI Laboratory by communication dated 12/9/71, advised that an examination of the towel submitted by the Las Vegas Office, disclosed a brown head hair clipping and a brown limb hair, both of Caucasian origin. The report continued that the head hair clipping is suitable for significant comparison results, but that the limb hair possesses too few unique microscopic characteristics to be of value for that purpose.

The Laboratory also advised that the hairs obtained from the towel have been mounted on a glass microscopic slide. They suggested that if microscopic comparisons between the head hair clipping and a known head hair sample, were desired, that the glass microscopic slide containing the hair clipping should be resubmitted to the Laboratory by the Las Vegas Office.

The contents of the ash tray, the towel and the microscopic slide were returned by the Laboratory to the Las Vegas Office and are being held by the Las Vegas Division as evidence.

The fingerprint lifts made during the search of the interior of the aircraft in the area where the hijacker was known to have been, such as the rear door, the area around the door, the lavatory door, as well as the seat area, susceptible to dusting, were submitted for fingerprint examination, but no fingerprints of value were found on any of the latents thus obtained.
