Result of examination:

The Ampex C-60 magnetic tape cassette identified as having been found on body 31-I was found to be unplayable due to the body residues within the cassette housing and on the tape service. The magnetic tape was removed from the housing and cleaned with isopropyl alcohol. The tape was then placed in a Maxell C 46 cassette housing.

One copy of the cassette was made on a 5 inch real of magnetic tape recorded at 3 3/4 inches per second in a full track configuration. Review of the cassette revealed approximately 15 minutes of music on one side of the cassette. The other side revealed no speech information.

Two photographic prints of the paper items described above; two photographic contact prints of the three rolls of film described above and a copy of the tape cassette are being furnished to San Francisco under separate cover. The submitted material is currently retained at FBIHQ. You will be advised separately of any significant information developed from examination of the submitted ammunition.
