INSTRUCTIONS [guess: BACKGROUND] INFO
---
Reference Seattle letter to Albany dated 11/30/71.
Referenced letter sets forth background information concerning captioned matter and indicates that the pertinent area of time involved is between 2:00 p.m. and 11:00 p.m. on November 24, 1971, which was the day before Thanksgiving. When information is developed indicating a possible suspect in this matter, offices are requested to determine the whereabouts of the suspects during the pertinent period of time and if this can be done readily, no further investigation is necessary. If this cannot be done readily, glossy photographs should be obtained and forwarded with copies to Minneapolis, Portland and Seattle for display to witnesses at those locations.
If this does not resolve the involvement of the suspect, leads will then be set forth to establish his whereabouts at the pertinent time. These leads should all be covered as quickly as possible.
