ROXBURY – Late Wednesday night, state police were trying to determine what led to a man being found bleeding from a head injury, lying in a driveway of a home at 91 Roxbury Road.

Joseph Gallant, a volunteer firefighter, was found by Dan and Pamela Bulger, shortly before 9 p.m.

Gallant’s car was parked diagonally across the Bulgers’ driveway. He had scrawled the number “33” in blood on his car.

According to Maine State Trooper Kyle Tilsley, who, along with Trooper Tyler Stevenson, is investigating the incident, Gallant was on his way home from work on Route 17, when a vehicle forced him off the road. Despite his injury, he was able to get the car back on the road and drive to the Bulgers’ home, according to Tilsley.

Police are unsure how he got the head injury – whether his head struck the vehicle, or if he may have been struck by something in the vehicle.

Pamela Bulger told Roxbury firefighter Matt Patenaude that she and her husband were watching television when Dan Bulger looked outside and asked her if the car in their driveway was Joseph Gallant’s.

They went outside to look and found the injured man lying in the driveway. Pamela Bulger said she called 911 right away.

“He tried to talk to us. He tried to tell us, he was writing in blood on his car that someone hit him,” she said.

Gallant was taken to Rumford Hospital where he was treated for cuts on his head and released.

Shortly before 9 p.m., Roxbury Fire Department safety officer Tim Gallant, Joseph Gallant’s father, arrived at the scene.

It was the second unusual call that Roxbury firefighters responded to that day, Patenaude said. At about 4:30 p.m., they were sent to a rollover farther up Route 120 near the satellite station between Andover and Roxbury Pond. Joseph Gallant, who has been a Roxbury firefighter for more than a year, went with them.

Patenaude said when they arrived, along with Andover firefighters and state police, the car, which was said to have been seen on its side, wasn’t there. They did find evidence in the snow where it had crashed.
