POLAND – Alcohol, not speed or road conditions, was the cause of a Christmas Eve crash on Route 122 that claimed the lives of six people, according to an accident reconstruction report released Thursday.

Cumberland County Sheriff’s Deputy Andrew Hannah concluded that 20-year-old Michael Cournoyer’s blood-alcohol content of .14 percent was the primary cause of the early-morning, two-vehicle wreck.

Killed in the crash were Cournoyer and his passengers, Jacob Roy, 20; Robert Bruce, 19; and Matthew Manley, 18. In the second car, 27-year-old Steven Walton was killed along with his fiancee, 25-year-old Laura Caron.

Police at the time described the crash as the deadliest in recent memory. It was the sixth-deadliest accident in Maine history.

The 22-page accident report consists mostly of charts, sketches, photographs, diagrams and mathematical formulas Hannah used to estimate vehicle speed and other possible factors.

The conclusion on the seventh page consists of just four sentences, which state that speed and road conditions were not contributing factors, and that Walton had not been drinking before the crash.

Police said Cournoyer was drunk and had a suspended license when he lost control of a friend’s Nissan Altima, crossed the center line, and spun in front of Walton’s Dodge Spirit, which was traveling in the opposite direction.

After the collision, the Nissan slammed into a utility pole and then flipped onto its roof, according to the report. Police estimated Cournoyer’s speed at between 42 and 58 mph when he lost control of the car. Walton’s speed at the time of impact was estimated at between 11 and 15 mph.

Investigators believe Cournoyer and his passengers were returning from a party in Poland when they crashed. Police are still investigating the details that led up to the wreck. No charges have been filed.
