ALL LAW ENFORCEMENT AGENCIES IN STATE OF OREGON

Re: UNKNOWN SUBJECT WHO HIJACKED NORTHWEST ORIENT AIRLINES 727 JET AIRCRAFT BETWEEN PORTLAND, OREGON, AND SEATTLE, WASHINGTON, ON NOVEMBER 24, 1971.

Enclosed for your office is an artist's sketch and on the back of the sketch a description of the individual who hijacked the Northwest Orient Airlines aircraft on November 24, 1971.

The hijacker is very possibly a person who has disappeared from his usual abode and possibly from his job. Your assistance is requested in identifying persons who have been missing since about the time the hijacking occurred and who could fit the description of this individual.

I would greatly appreciate your furnishing information regarding persons known to your agency who have been missing recently and who could be considered suspects in this case.

In the event you have no pertinent information as to missing persons, please reply on this communication stating a check of your records was negative. It is our desire to receive a response from all to whom this letter is sent.

CONSIDER UNKNOWN SUBJECT ARMED AND DANGEROUS.

Thank you for your assistance.

Very truly yours,

J.L. MATTSON Special Agent in Charge
