The trail of legendary skyjacker D.B. Cooper may have grown cold again. Richard Tosaw, who has been searching for Cooper since he bailed out of a Northwest Airlines plane in 1971 with $200,000 in ransom, claimed to have found an 18-square-inch section of a parachute in a Washington forest this week, but Earl Cossey, the man who packed Cooper's parachute, says it's not the same one. "It looks like one of those G.I. Joe parachutes," Cossey said. Tosaw says the section of the parachute was found about 1 mile the Columbia River from where a boy found $5,800 of the ransom money in 1980.
