CHICOPEE — A Chicopee police officer, who was first to arrive at a crash involving a state trooper who was allegedly “cocked” when he plowed his personal pickup truck into an SUV, told investigators the aftermath was memorable.

“I’ll never forget that accident as long as I live! There was debris everywhere,” Chicopee Police Officer Przemslaw Szura told a different trooper investigating the crash, which happened shortly after 2:30 a.m. July 21 on Burnett Road.

Trooper Jason Welch, 35, of Ayer, pleaded not guilty in Chicopee District Court on Sept. 5 to operating under the influence of liquor causing serious injury, reckless operation of a motor vehicle, operating under the influence of liquor and failure to take care in stopping.

There is a prosecution motion pending to amend the charges against Welch to elevate a misdemeanor to a felony. State police filed a petition to revoke Welch’s license under an “immediate threat” provision the day after the accident, court records show.

Welch remains on restricted duty pending a judge’s decision on the prosecution motion, state police spokesman David Procopio said Wednesday. Welch’s passenger, identified in a police report obtained by The Republican as Trooper Timothy Stone, has not faced any discipline, Procopio said.

Welch told investigators that he fell asleep while driving on Route 291. He was traveling at 58 mph and didn’t brake when he collided with the SUV, according to an accident reconstruction report.

Szura reported that the rear end of the Ford Expedition was destroyed and a passenger inside was trapped and “couldn’t feel his legs.” The front end of Welch’s pickup was crushed.

“The second I got to the accident I could smell the beer. ... I hate to throw another guy under the bus, but both of them were cocked,” Szura told state police Lt. Adam Hakkarainen, according to the narrative.

Stone, who suffered a broken hip, told investigators he was asleep at the time of the crash, and that he couldn’t remember where they had been or what they were drinking before they got in the truck.

“I can’t comment on that. I’m on painkillers,” Stone said from a hospital bed at Baystate Medical Center in Springfield, the report states.

Stone said Welch had not been drinking.

He asked for a union representative while he was in the hospital, the report states. Asked where they were going, Stone said: “No clue.”

The crash occurred on the heels of a state police overtime scandal, and just before former state police union head Dana Pullman was charged in a kickback and embezzlement scheme along with a Beacon Hill lobbyist.

Szura told troopers Welch appealed to him when he arrived at the accident.

“You got to help us both out. We’re both troopers,” Welch said to Szura, according to the report.

“You’ve got to be f---ing kidding me!” Szura responded, and called a supervisor, the narrative says.

Szura said there were cans of Coors Light and the top of a white cooler strewn about the crash scene, and bottles of Corona Light beer in Welch’s truck. A can of beer remained perched on top of the truck even after the crash, another trooper reported. Other first responders also reported that the crash scene reeked of alcohol and there was “a lot of blood” in the truck.

One trooper said it smelled like “stale alcohol on a summer day. It infiltrated your nose,” the report states. The same trooper said Welch told her on-scene that he was worried about his girlfriend finding out about the crash.

Some troopers who responded to the scene said they recognized Welch because he was a drill instructor at the Massachusetts State Police Academy.

As for the couple in the Ford Expedition, they were on their first date, they told police. The woman driving the car told investigators she discovered a full bottle of Corona beer in her back seat after the crash although she doesn’t drink beer and her date didn’t bring any.

She was the only car stopped at a red light before Welch’s truck smashed into hers. Although she saw the truck barreling up behind her, she didn’t have time to react, she told police.

The woman said her passenger initially believed he was paralyzed in the crash but was not. He did break two vertebrae in his back.

Welch cracked two ribs, the report states.

His eyes misted up when police reported the charges in a criminal complaint against him and he blurted: “I’m sorry,” the narrative says.

“The patient was driving drunk. He states that he has no recollection of the event but feels like an idiot," a doctor reported to police.

Welch’s blood alcohol content came in at 0.255, the report says.
