A person reads every report. Corrections are made by hand, to the data — titles, dates, names, which pages belong together — never to the scans, and they can take a while to appear.

Specimens received 11/29/76

Q4 Trousers

Result of examination:

The Q4 trousers have a waistband measurement of 42" and an inseam measurement of approximately 31". They are constructed with a wool and silk blend utilizing blue, tan and black colors.

A fragmented laundry tag stapled to the Q4 fly area bears the serial number A 317 and the following writing: ONE MARTI. A partial letter follows the letter I and the possibility of the phrase "ONE HOUR MARTINIZING" should possibly be considered.

The FBI Laboratory does not have a laundry tag reference file. No invisible laundry markings were found on Q4. No hairs were found on Q4.

No blood or other body fluid stains were identified on specimen Q4.
