SEATTLE, March 26 (UPI) -- FBI agents in Seattle are in the process of determining whether a parachute found in a field by children belonged to missing 1970s skyjacker D.B.Cooper.

The deteriorated parachute was discovered between the towns of Ariel and Amboy, Washington, identified as the area where Cooper parachuted out of a Northwest Orient jetliner in 1971 with $200,000 in ransom money, KOIN-TV, Portland, reported.

Agent Larry Carr told the station that after the parachute has been cleaned the FBI is hoping to find a label that would identify it as a companion to the reserve parachute Cooper left behind on the plane.

In 1980, $5,800 of Cooper's ransom money was found by a family on a picnic at a Columbia River beach near Vancouver.

Since then other evidence has been gathered by the FBI including a clip-on tie and clasp Cooper was wearing when he disappeared.

KOIN-TV said FBI agents have been able to extract Cooper's DNA.
