A small South Carolina parts supplier collected about $20.5 million over six years from the Pentagon for fraudulent shipping costs, including $998,798 for sending two 19-cent washers to a Texas base, U.S. officials said.

C&D's fraudulent billing started in 2000, [Cynthia] Stroot, the Defense Criminal Investigative Service's chief agent in Raleigh, North Carolina, said in an interview. ``As time went on they got more aggressive in the amounts they put in.''

The price the military paid for each item shipped rarely reached $100 and totaled just $68,000 over the six years in contrast to the $20.5 million paid for shipping, she said.

``The majority, if not all of these parts, were going to high-priority, conflict areas — that's why they got paid,'' Stroot said. If the item was earmarked ``priority,'' destined for the military in Iraq, Afghanistan or certain other locations, ``there was no oversight.''

The scheme unraveled in September after a purchasing agent noticed a bill for shipping two more 19-cent washers: $969,000. That order was rejected and a review turned up the $998,798 payment earlier that month for shipping two 19-cent washers to Fort Bliss, Texas, Stroot said.
