Police Use Awesome Powers of Investigation More than 20 years ago, somebody found a wallet at Wyoming's Yellowstone National Park. All the police's investigative powers couldn't locate the owner, so it gathered dust in a police property room. Finally, a technician reopened the cold case. Using sophisticated technology, he opened the wallet and found the owner's name and Social Security number. Lisa Tonks, of Indiana, now has her wallet back, plus the $177 inside.
