Trooper David Cunniff, 35, was inside his patrol car behind the car he had pulled over on Interstate 90's eastbound lanes around 8:20 p.m. Monday, when his cruiser was hit by the big rig and he was partially thrown from his vehicle, State police Superintendent Joseph D'Amico said. The truck also hit the car, injuring the driver.
The trooper suffered massive head trauma and was airlifted to Albany Medical Center, where he died Tuesday afternoon, the superintendent said.
The announcement of the trooper's death came in a news release soon after D'Amico had finished giving details of the crash during a news conference held at the State Police Academy in Albany.
D'Amico said neither alcohol nor weather was considered a factor in the crash, and police were still investigating.
He said the trooper's vehicle and the car Cunniff stopped were near Exit 27 in Amsterdam, about 30 miles northwest of Albany. He said the tractor-trailer was traveling east in the right lane and drove off the road for some unknown reason near where the trooper's car was idling with its emergency lights on.
The truck slammed into the back of the trooper's car, sending it 50 yards into an embankment, then rammed the other car, moving it 75 yards and landing on top of it, D'Amico said.
Police said the driver of the car, 57-year-old Eric Heller of Stone Creek in Warren County, was in fair condition at the Albany hospital. The truck driver, Gary Blakley, 65, of Ridgeway, Ontario, wasn't injured. His truck was hauling insulation, police said.
Both eastbound lanes of I-90 were closed for nearly 10 hours after the crash, and eastbound traffic was detoured off the highway at an exit near Syracuse.
Cunniff, of Duanesburg, was a nine-year state police veteran who had been working with Thruway patrol since 2009, the superintendent said. He is survived by his wife and two young sons.
Cunniff's death is the second within the past several weeks involving an on-duty trooper. On Nov. 20, Trooper Ross Riley died after falling from a ledge in a gorge in a state park in western New York during a training exercise.
In 2011, New York state instituted its "move over" law that requires motorists to slow down and move over if possible when approaching police and emergency vehicles pulled over alongside the road. Three months after the law went into effect, Trooper Kevin Dobson was killed when he was hit by a vehicle while issuing a speeding ticket alongside a highway in suburban Buffalo.
