Investigators Crack DB Cooper Code, Identify Suspect With Possible CIA Connections (seattlepi.com)
An anonymous reader quotes the Seattle Post-Intelligencer:
A private investigative team announced Thursday morning that members now believe D.B. Cooper was a black ops CIA operative possibly even involved with Iran-Contra, and that his identity has been actively hidden by government agents. The 40-member cold-case team comprised of several former FBI agents and led by Thomas and Dawna Colbert made its latest reveal after a code breaker working with the team found connections in each of five letters allegedly sent by Cooper in the days following the famed hijacking in 1971.
What's more, several people who knew Colbert's top suspect, a man named Robert W. Rackstraw, have noted possible connections to the CIA and to top-secret operations, Colbert said. "The new decryptions include a dare to agents, directives to apparent partners, and a startling claim that is followed by Rackstraw's own initials: If captured, he expects a get-out-of-jail card from a federal spy agency," Colbert said in a news release... In a brief phone call last year, Rackstraw only told SeattlePI to verify Colbert's claims; he didn't issue a denial, or comment further on Colbert's investigation...
Late last year, Colbert's team obtained a fifth letter allegedly sent by Cooper that Colbert said supports a possible FBI cover-up, but also included random letters and numbers. A code breaker on Colbert's team was able to decode the letters and numbers and find they pointed to three Army units Rackstraw was connected to during his military service in Vietnam. The code was meant to serve as a signal to his co-conspirators that he was alive and well after the jump, Colbert said... Another letter, in which Cooper claimed to be CIA openly, also had the letters "RWR" at the end -- the initials of Robert W. Rackstraw, according to Colbert.

I know reading TFA is hard, but at least read the summary. These were private investigators doing this in their own time. The team includes a whole bunch of former FBI and other former government people, but none of your tax money is going to this.
A quick look at the wikipedia page (https://en.wikipedia.org/wiki/D._B._Cooper) reveals that in 2007, FBI secured DNA traces from the hijacker's tie.
If this DNA matches the suspect, this would be hard to explain.
This is not the first time Rackstraw is under investigation. He appeared already in 1978 in the investigation, but this is far from the only suspect that has been identified. The Wikipedia article lists ten other individuals that - on the surface of things - appear just as likely as him.
I'd say that this is another hypothesis generated by the famousness of the case, like other famous crime cases in the past. The "Jack the ripper" suspect list on Wikipedia counts no less than 29 persons.
