Wesley A. Pulsifer, 29, began to pull his motorcyle over with emergency lights of State Police flashing behind him in Knox on Sunday night, but sped up and led a Trooper through three counties over 100 miles per hour, police say.

Pulsifer, of 19 White Road in Altamont, was charged with driving while intoxicated, a felony he has been charged with in the past, said police.

Trooper T. Burns saw Pulsifer riding west 74 miles per hour on Route 146 in Knox when he tried to pull him over on July 14, police said, describing unfolding events this way: Burns followed Pulsifer onto Route 443 into Schoharie County, then north on Route 30. He stopped pursuing Pulsifer on Route 7, in a 55 miles-per-hour speed zone, when the motorcyclist reached speeds as high as 107 miles per hour. Pulsifer crashed near 5708 Schoharie Turnpike.

“The road sign was ripped from the ground and thrown quite a distance, but he had no apparent injuries on the outside of his body,” said Burns, suggesting his injuries were internal. Burns said the roads were dry.

Pulsifer was airlifted with a MedFlight helicopter to Albany Medical Center, said Sergeant Tryon Lecakes of the State Police.

Pulsifer was charged with two felonies, driving while intoxicated and aggravated unlicensed operation of a motor vehicle; a violation, unlawful possession of marijuana; and three misdemeanors — unlawfully dealing with fireworks, unlawful fleeing from a police officer, and operating a vehicle without an interlock device.

An interlock device is installed on the vehicle of a driver who has been charged with DWI, requiring the person to pass a breath-sample test to detect an absence of alcohol before the engine will start.

Police said Pulsifer had numerous Vehicle and Traffic Law charges, including reckless driving, speeding, failing to stop at a stop sign, failing to signal a turn, failing to keep right, and driving the to left of pavement markings.
