A federal grand jury indicted a Carroll County man Wednesday after he allegedly submitted $2 million worth of fraudulent invoice charges while his company performed repairs and maintenance at U.S. Postal Service facilities, the U.S. Attorney’s Office for Maryland announced Thursday.
According to the Office of the U.S. Attorney’s Office for the District of Maryland, Liberto served as the president of Frederick-based Sierra Construction LLC. Between 2014 and 2018, the company contracted with EMCOR Facilities Services’ Customer Solutions Centers to provide repair services to Postal Service (USPS) facilities.
“EMCOR acted as the clearing house responsible for receiving service calls for needed maintenance and repair work on its customers’ facilities, including the USPS, and assigning such work to service providers, such as Liberto and Sierra,” the U.S. Attorney’s Office said in a news release.
Liberto allegedly schemed “to defraud EMCOR and USPS by concealing Sierra’s use of subcontractors to carry out maintenance work it was assigned to perform, making false statements, and providing false documents to EMCOR, in order to overcharge the USPS,” according to the release. Through this overbilling, the indictment alleges, Sierra obtained about $2 million.
