A woman claiming to be the niece of infamous skyjacker D.B. Cooper has spoken to ABC News in an exclusive interview about her role in the recently re-ignited 40-year-old cold case that has haunted the FBI for years.
Marla Cooper told ABC News that she has provided the FBI with a guitar strap and a Christmas photo of a man pictured with the same strap who she says is her uncle, Lynn Doyle Cooper.
After clarifying her childhood memories surrounding the incident and more recent conversations with her parents, she is now sure that her uncle is in fact the notorious man who hijacked and threatened to blow up a commercial plane flying to Seattle in 1971, then parachuted to the ground with $200,000 in hand.
"I'm certain he was my uncle, Lynn Doyle Cooper. Who we called L.D. Cooper," she told ABC News.
The FBI is now searching an item they received for fingerprints at their forensic lab in Quantico, Va., which will be checked against partial fingerprints obtained from the hijacking. Meanwhile they are hunting for evidence to prove L.D. Cooper was on that plane in 1971.
The real identity of D.B. Cooper has been a mystery since November 24, 1971, when a man calling himself Dan Cooper hijacked a Northwest Orient Airlines plane bound for Seattle from Portland. He ordered the plane to land and demanded a $200,000 ransom and a parachute.
