Researchers trying to solve the infamous D.B. Cooper case believe that they have cracked a code contained in one of the notorious skyjacker's letters.
The missive in question was released to the public last year by the FBI and is thought to be a genuine letter written by Cooper to several national newspapers following his daring caper.
Tenacious investigator and former C2C guest Tom Colbert along with his team of researchers studied the new evidence and discovered a rather curious detail.
At the bottom of the letter are three series of numbers which have seemingly no explanation nor purpose.
This piqued the interest of a code breaker who is working with Colbert and the numbers were subsequently identified.
Find out they believe the code signified at the Coast to Coast AM website.
