A parachute that may be connected to infamous hijacker D.B. Cooper is reigniting interest in the only unsolved hijacking in U.S. aviation history.

The big picture: A series of stories marking the 53rd anniversary last weekend of D.B. Cooper's infamous heist highlights the 2022 discovery of a modified parachute on the property of a former suspect.

State of play: Despite years of investigation, the FBI closed the D.B. Cooper case in 2016, leaving it officially unsolved.

Driving the news: D.B. Cooper sleuth and YouTuber Dan Gryder found the parachute two years ago on a North Carolina property that belonged to the family of the late Richard McCoy II, the Cowboy State Daily reported.
