Well that was a BIG reveal...
Most people will think McCoy was DB Cooper. Buy the McCoy book, it will go up.
Rataczak said they saw Portland and Cooper was gone by that time.. So, he didn't jump over the Columbia.. and those diatoms.
But that has nothing to do with the McCoy claim.
McCoy's kids sincerely believe he was Cooper, they have come forward after the death of their mother and want their father to get credit for the Cooper hijacking. That alone will convince a lot of people.
Problem is there isn't any new evidence here, McCoy's alibi was always sketchy and he does not fit the witness descriptions.. fingerprints didn't match... there is no new evidence. The claim that he was disguised with nobody noticing is not believable.
His kids were small and Denise the babysitter thought the parents were gone for 3 days around that time.. but no specifics.
This is the same issue with other suspects,, personal opinions and recollections.. but this will have more weight because McCoy actually did a similar hijacking..
McCoy will be moved to the top of the (public) suspect list but I just didn't hear any new evidence.
Also, for his UAL hijacking, McCoy's photo was id'd by witnesses and he left lots of fingerprints. He left the note behind..
