POLAND – One of the drivers in a car crash that killed six people early Sunday had a suspended license.

Michael Cournoyer, 20, lost it after a conviction for operating under the influence back in March, according to state records. Specifics on the incident were not available Monday night.

Killed on Route 122 just after midnight were Cournoyer, of Auburn and his passengers, Jacob Roy, 20, of Lewiston, Robert Bruce, 19, of Auburn, and Matthew Manley, 18, of Lewiston.

Cournoyer’s Nissan Altima collided with a Dodge Spirit driven by Steven Walton, 27, police said. Walton and his fiance, Laura Caron, 26, both of Poland, also died.

Police believe one of the cars skidded out of control on black ice and slid into the path of the oncoming vehicle. The accident happened on a curve of Route 122 between Verrill and Bishop roads.

Four people died on impact. A fifth died at Central Maine Medical Center in Lewiston an hour after the head-on collision, police said. The sixth victim died hours later at the hospital.

“As a standard protocol, alcohol tests will be performed on the two operators as part of the investigation,” Androscoggin Sheriff’s Office Detective William Gagne said hours after the crash. “It is still too early to rule on the cause and a final determination may take several weeks to months.”

Deputies from the Cumberland County Sheriff’s Office were called in to assist the investigation.

ASO Sgt. Rielly Bryant said Monday evening that police were still investigating where the young men were that night.

According to family, Walton had picked Caron up after a late shift at work, and the pair had been heading home after last-minute Christmas shopping.

“We’re investigating everything at this point,” Bryant said. Cournoyer’s suspension “is obviously a portion of the investigation Detective Gagne is working on.”

Public Safety spokesman Steve McCausland said Sunday’s accident was the sixth-deadliest in Maine history.

“Suspended drivers have been a focal point of the state police and all (agencies) in the past year,” he said. “He was suspended – he shouldn’t have been on the road.”
