LUNENBURG — An accident on Dec. 2 killed two men after one of their vehicles moved into the oncoming lane, crashing head-on into another vehicle, said police Lt. James Marino.

Salvatore J. Spinale Jr., 75, of 11 Longley Rd., Shirley, and Jonathan A. Raymond, 27, of Lawton St., Ayer, died after being taken to area hospitals, he said.

Rescue workers had transported Spinale to the Boston Medical Center by MedFlight helicopter, he said, and sent Raymond to Nashoba Valley Medical Center by ambulance.

Raymond’s 1999 Ford Taurus crashed into Spinale’s 2003 Ford Taurus when Raymond’s car moved into the oncoming lane, Marino said.

The accident occurred at a sharp turn on Massachusetts Avenue near Pine Street at about 2 p.m.

“Raymond was coming westbound and went into the eastbound lane and hit Spinale, who was driving eastbound,” said Marino.

It took firefighters 40 minutes to extricate the two victims from their vehicles.

Janice Beauregard, one of Spinale’s neighbors, said he was an “integral part” of his neighborhood.

He had two children and 13 grandchildren, all of whom visited him frequently, she said.

“He was a good neighbor, a good friend, a helping hand,” she said. “He was a good person.”

Neither of the victims’ families could be reached for comment.

The point of impact was near the far edge of the road, Marino said, suggesting Spinale attempted to swerve out of the way.

There are still unanswered questions related to the crash, he said.

“It’s unknown why he might have gone over into the other lane,” he said. “It appeared speed may have played a factor in the part of Jonathan Raymond.”

Officer Patrick Barney, along with the state police reconstruction team, are continuing the investigation, said Marino.
