CHARLESTON, W.Va. (WCHS) — A Kentucky man pleaded guilty on Thursday to a conspiracy to overcharge the Boone County School system alongside a former maintenance director, court records said.

Jesse Marks, 65, of Rush, Kentucky was charged with conspiracy to commit mail fraud after he worked with Michael David Baker, 47, of Foster, West Virginia in a plot overbill the school system for janitorial and custodial supplies, according to the U.S. Attorney’s Office, Southern District of West Virginia.

At the time of the plot, Marks was the owner of Rush Enterprises and was contacted by Barker in November 2019 for supplies including hand soap, garbage bags, facemasks and hand sanitizer. Marks admitted that the two entered an overbilling scheme and inflated the number of products being delivered.

Barker submitted the invoices to Boone County Schools on behalf of Rush Enterprises and the invoices were paid by the district using mailed checks. Once the mailed checks were received, Marks allegedly deposited the checks into a business account and wrote himself checks to deliver to Baker, initially evenly splitting the profit, before Baker began receiving a 55% of the share in the scheme.

Marks estimated that of the $4.3 million in products ordered by Boone County Schools, nearly $3.5 million worth was never delivered.

Marks pleaded guilty to conspiracy to commit mail fraud and faces up to 20 years in prison, up to three years of supervised release and a $250,000 fine, as well as restitution that will be determined by the Court. He is scheduled to be sentenced on June 16.

Baker was federally indicted on 18-charges, including conspiracy to commit mail fraud, theft concerning programs receiving federal funds and money laundering in December. His trial is scheduled for April 15.
