PETERBOROUGH — Investigators have concluded their investigation into the collision on Route 202 in February that took the life of a pedestrian, but were unable to determine the exact cause.

The collision occurred Feb. 28 around 8:30 p.m.

The pedestrian, Michael J. Dugrenier, 51, of Peterborough, was pronounced dead at the scene. The driver of the car, Peter P. Blais, 34, of Concord, was driving northbound along Hancock Road in the area of Pheasant Road when his car struck Dugrenier.

Police chief Scott Guinard said this week that the Peterborough Police Department and the New Hampshire State Police Collision Analysis and Reconstruction Unit have completed the combined investigation into the collision

“Investigators could not determine the exact cause of this collision needed to lay fault on either party, Blais or Dugrenier,” Guinard said in a press release.

At the time of the collision, that stretch of Route 202 was dark, there were no street lights and Dugrenier was wearing dark clothing at the time, Guinard wrote.

“According to information provided by the NH Medical Examiner’s office, Dugrenier had an unusually high blood-alcohol level at the time of the collision,” Guinard wrote.

Dugrenier was found in close proximity to the white painted fog line, but investigators could not determine what his exact location was at the time of the collision.

Investigators did not find evidence Blais was impaired by drugs or alcohol, Guinard wrote.

“There is no evidence or statements made by Blais or the eyewitness to indicate that speed was a factor in this collision,” Guinard wrote.

The posted speed limit is 40 mph.

There is no evidence the car experienced mechanical failure or defects prior to or at the time of the accident and the roadway surface was straight, level, paved and dry at the time of the accident.
