DNA No Match, DB Cooper Still a Mystery

DNA testing has failed to establish a link between a new suspect in the DB Cooper case and the man who vanished after hijacking a plane 40 years ago, the FBI says. DNA from family members of the suspect, who died 10 years ago, failed to match any of the strands of DNA from three different people found on a necktie believed to have been worn by the hijacker, reports the AP.

The FBI says it hasn't ruled out the new suspect, however, as there is no proof that any of the DNA on the tie belonged to the hijacker, Reuters notes. "There are some questions about the tie itself," said a special agent. "Was it a used tie, a borrowed tie?" Investigators are working with the suspect's family members to obtain fingerprints to compare to those left behind after the man known as DB Cooper parachuted from a plane with $200,000 in cash.
