John Fray on Nov. 24:
The November 24, 1971,
Hijacking by Dan Cooper
Has Never Been Solved
After 53 Years.

Most researchers believe that the hijacker perished shortly after he jumped out of the plane, probably because he was not able to deploy the parachute pack which he had donned. A small segment of the investigators thinks that he may have survived, but he lost the ransom money in the turbulence of the tail stream of the aircraft.

As for the hijacker's identity, his DNA exists in a liquid solution currently being analyzed in a laboratory. The solution was derived from a filter element of a machine which vacuumed trace particulates from the clip-on necktie which he left behind on the aircraft. Yes, other individuals have handled the necktie over the years, and their DNA profiles are also contained in the solution. There is a reasonable chance that advanced technology will be able to isolate each of the DNA profiles in the solution and eventually home in on that particular profile which is that of the hijacker.
