Vincent L. Leibell, III (born August 6, 1946) is a former politician from Putnam County, New York. After a long career in the New York State Legislature, Leibell ran for and was elected county executive in 2010, but resigned prior to taking office following an investigation by the Federal Bureau of Investigation which led to his arrest and subsequent conviction on federal corruption charges.
His resignation was in connection with a Federal plea arrangement stemming from two felony convictions relating to kickbacks Leibell had received while using his position as State Senator to steer taxpayer monies towards two local non-profit agencies which he controlled. In November 2012, he was released to a halfway house after completed serving 17-months of his 21-month prison sentence at the Federal Correctional Institute in Loretto, Pennsylvania.
Leibell was born in New York City. His grandfather and namesake was a federal judge, Vincent L. Leibell.
Leibell worked as an Assistant District Attorney in the Westchester County District Attorney's office. He was a Captain in the New York Naval Militia.
He is married, with three children. He received his BA and JD from Saint John's University, as well as an MPA from New York University. Because he was convicted of two felony counts of corruption in 2010, Leibell was forced to forfeit his law license. According to the Daily News, Leibell plead guilty to two of seventeen charges to end a Federal investigation of him into non-profit foundations he controlled and land deals that were arranged through those foundations, including the construction of a large house for the eight-term senator.
