The Legend of D B Cooper 
Death by Natural Causes

Dennis and Rena:

Perhaps this letter will explain many things. I know you have both wondered why I’ve remained so distant and never tried to contact you the last few years.

My past life was very mixed up, an inborn problem that made a normal life impossible for me. Your mother and I separated because of it, and I’m sure you must remember something, Dennis. Rena was too young then.

To be brief, no matter how hard I’ve tried in the past, I have never been able to accept myself as a male, and nearing the brink of possible suicide, I submitted myself to extensive medical and psychological research. It was determined that I was a transsexual, physically a male, but more basically a female. The magnitude of the predominant sex could not be reduced. In December 1969, I underwent conversion surgery for sex-reassignment. I am no longer a would be man and I have my true identity now, and am much happier for it.
