cause an immediate search of any Army records under Mc Coy's name in an effort to locate any hand printing and handwriting of Mc Coy. This was done and the writing samples were forwarded to the FBI Laboratory in Washington, D. C.

At this point, it was felt an interview of Mc Coy might prove beneficial. Mc Coy was located and interviewed at the Army Operations Center at the Salt Lake City Airport and during the interview he denied any participation in or knowledge of the hijacking. He did, however, furnish the interviewing Agents with a sample of his hand printing. The message- "Everybody off now except the stewardesses. They stay put. Get the hell off the GD. Be quick about it -- use this runway" was dictated to him and he printed it. This message was sent to the FBI Laboratory in Washington for comparison with the message found on the airplane. Mc Coy continued to claim innocence as was released.

Meanwhile, the Laboratory in Washington had been busy with the evidence they had already received. An expert in handwriting had compared the note found on the airplane with Mc Coy's known writing samples which had been obtained from military service records. It was determined that Mc Coy had written the note. Fingerprint experts had compared latent prints with Mc Coy's fingerprints and it was determined that a print on the "Mainliner Magazine" in the seat occupied by the hijacker was made by Mc Coy.
