Long Island bus executive John B. Mensch is headed to federal prison after a years-long check-kiting scheme that prosecutors say kept his failing companies rolling on money they did not actually have.
Mensch, 55, of Quogue, the owner and chief executive of a Long Island bus conglomerate, was sentenced Wednesday in federal court in Central Islip to 18 months in prison and ordered to pay $9,326,366.03 in restitution. Prosecutors said he kept his insolvent businesses afloat by cycling worthless checks between bank accounts so East End could pull cash it was not entitled to, drawing down funds before the checks cleared. Mensch pleaded guilty in October 2024 to a bank-fraud conspiracy in the case, which is docketed as E.D.N.Y. No. 24-CR-334 (NJC).
What check-kiting looks like
Check-kiting is a form of bank fraud that exploits the lag between when a check is deposited and when it actually clears, often called the “float.” By shuttling unpaid checks and wire transfers among accounts, a fraudster can create fictitious balances and temporarily trick banks into releasing money that is not really there. As the DOJ Criminal Resource Manual explains, that conduct can be charged as bank fraud when it is used to deceive financial institutions and illegally obtain funds, and prosecutors routinely treat long-running or high-dollar schemes as serious federal cases.
How prosecutors say Mensch hid insolvency
According to the U.S. Attorney’s Office for the Eastern District of New York, Mensch and other East End executives secured expedited check-clearing privileges at banks in Suffolk and Orange counties. From 2017 through September 2018, they repeatedly passed unpaid checks between multiple East End accounts to fabricate the appearance of available funds, even as the businesses were operating at a deficit.
Prosecutors said the circular flow of worthless checks enabled East End to obtain nearly $10 million that was spent while the company was effectively insolvent. “Today’s sentence should serve to warn fraudsters like the defendant that the loss of freedom and restitution to victims is the price of their crimes,” U.S. Attorney Joseph Nocella Jr. said in a statement, which the office also posted on X.
Law enforcement reaction
Officials from the FBI and the U.S. Secret Service, quoted in the U.S. Attorney’s announcement, said the scheme threatened the integrity of the banking system and hurt creditors, customers and employees along the way. “This was not a victimless crime,” the release stated while outlining the multi-agency investigation that led to Mensch’s prosecution. The U.S. Attorney’s Office said the Long Island Criminal Section handled the matter.
How this compares to other cases
Federal check-kiting prosecutions span a wide range in size and severity, with penalties tied heavily to how long the scheme lasted and how much money was siphoned off. In one recent high-profile case in the Northern District of Ohio, a defendant received a 97-month sentence and was ordered to repay more than $150 million after a multi-year check-kiting operation, underscoring how steep the consequences can become when the losses mount. See the U.S. Attorney's Office, Northern District of Ohio for that precedent.
What comes next
The restitution order converts the banks’ losses into a federal judgment that can be collected using civil enforcement tools in addition to the criminal sentence. Prosecutors said the outcome wraps up a lengthy investigation and reflects an ongoing federal focus on schemes that hide corporate failure and defraud financial institutions.
