Known for years in court documents only as “Public Official C”, former U.S. Army contracting officer In Seon Lim pleaded guilty to bribery charges Thursday — the final defendant in what authorities have called the biggest bid-rigging scheme in federal contracting history.
Lim, 48, took nearly a half-million dollars in cash, vacations and a luxury car from government contractors for his help in securing millions in defense contracts, according plea documents filed in federal court in Alexandria on Tuesday.
The ringleader of the scam, former U.S. Army Corps of Engineers contracting official Kerry Khan, 55, was sentenced to 19 years in prison last year. Overall, authorities say the Army scandal bilked taxpayers of more than $30 million.
The scam went undetected for years, in part, because Khan essentially had corrupt contractors build the cost of bribes into the contracts’ overhead estimates.
Referring to Lim as Public Official C, earlier court documents show he worked used the alias Joseph Lynn to email bid information to a company competing for a subcontract, taking golf trips and cash in exchange for the valuable insider information.
“I am full into this,” he wrote to a pair of contract company executives. “… I am investing my entire future on this.”
Lim, who is from Fairfax Station, faces up to 15 years in prison on a conspiracy charge as well as $375,000 in restitution to the IRS and Department of Defense and a forfeiture judgement of nearly $500,000.
“Lim sold out the public trust for cash, vacations and a Lexus,” Ron Machen, U.S. Attorney for the District of Columbia, said in a statement announcing the guilty plea Thursday.
