LITTLETON -- The two passengers who were killed when the pickup truck they were riding in crashed into a utility pole and rolled over on Route 119 in Littleton on Sunday morning have been identified by the Middlesex District Attorney's office as Taylor DeLuca of Groton, and Richard Mitchell of Dunstable.

They were both 21 years old.

DeLuca and Mitchell were members of the 2009 graduating class of Groton-Dunstable Regional High School, according to members of the school community.

Littleton Deputy Police Chief Matt King said speed appeared to have been a factor in the crash of the black Ford F-350 pickup truck, which occurred at about 5:20 a.m. at a curve in the roadway near the intersection with Gilson Road.

The vehicle had gone off the right side of the road and struck a utility pole, flipping the truck and ejecting the two passengers, according to Littleton Police Sgt. Robert Romilly. Both DeLuca and Mitchell were pronounced dead at the scene. Police do not believe that DeLuca or Mitchell were wearing seat belts, Romilly said.

The driver was taken to Lowell General Hospital and treated for non-life threatening injuries.

While the crash remained under investigation by the District Attorney's Office, Massachusetts State Police and Littleton police, the driver's identity has not been made public because no criminal charges have been filed, a spokesperson for District Attorney's office said Monday night.

"There does not appear to be any alcohol or drugs involved," King said of the crash.
