SAC, SEATTLE (164-81) 12/29/71 ASAC PAUL R. BIBLER NORJAK b6 RE: SUSPECT bie Supervisor MATHEISON called from the Bureau. He said that this had the Bureau bé somewhat excited since the ra ad just compared b7c Ory a letter which they got from the files of the Airlines Pilots Association with the typing on the letters which were sent to the WASHINGTON POST and several other newspapers. The Lab report says that this is the same style of type and certain limited characteristics suggest the possibility that they may have been prepared on the same typewriter. For this reason they want us to check him out today, if possible, and advise the Bureau by telephone or teletype. _ XL advised_SA to call Spokane and Everett bé and to check with nd get all investiga- b7c tion done today. Tt appears he fis stil employee and company records may show where he was on the day in question. ‘PRB: eon (3) DB Cooper-5200
