The Poughkeepsie man lost his leg below the knee in a November, 2007 accident. Listemann, 47, lost his prosthetic leg last month while skydiving in upstate New York.
The lower leg below the knee, with a foot clad in a running shoe, flew off after he jumped from the plane but before the parachute opened. Listemann says he's sure "it will show up eventually."
Listemann has distributed flyers throughout upstate Gardiner and hopes someone will find his prosthetic leg and call him.
