POMFRET – Police have identified the man who died following a collision with a New York State Department of Transportation truck in Chautauqua County on Monday afternoon.

New York State Police say despite life-saving measures by emergency responders, the driver of a 2006 Porsche Cayenne, 70-year-old, Thomas Sweat, of Buffalo, died as a result of the crash.

Sweat, troopers say, was traveling eastbound in the left lane when, for reasons still under investigation, his Porsche veered off the left side of the road and struck a thruway platform lift truck on the shoulder.

Troops went on to say his vehicle corrected into the lane before overcorrecting back to the left shoulder where he struck the back end of the Thruway truck.

A thruway employee, later identified as 52-year-old Christopher Cady, of Sherman, was in the truck at the time of the collision and suffered only minor injuries.

57-year-old Angela Singletary, of Buffalo, NY, was the passenger in the Porsche. She was air lifted by Mercy Flight to Erie County Medical Center.

Police say she suffered serious but non-life-threatening injuries.

The crash remains under investigation.
