BILLERICA, Mass. (WHDH) -- A deadly drive involving a Middlesex County corrections officer has a community in mourning.

Teddy Dillon, 27, was on duty --working midnight to 8 a.m. -- when he crashed his car into trees on Treble Cove Road on Wednesday at 4 a.m.

Investigators are trying to piece together what happened. They said Dillon was traveling northbound and for some reason he crashed into trees across the street. All that is left on the scene is a memorial in his name.

A mangled sheriff's cruiser was taken away from a one-car crash on Treble Cove Road. Dillon was from Lowell and had worked with the department since 2008. Officers saluted a car from the coroner’s office as it carried him away.

The crash happened on Biagotti Way, near the on ramp to Route 3. A neighbor said it is a very troublesome road with frequent accidents.

"I was in bed sleeping, sound asleep, when I heard a big crash. I put the shade up, looked outside, I knew it had to be close," said Jayne Biagotti, whose family the road is named for.

Biagotti said she immediately knew something was wrong when she heard the siren blaring after the crash.

"I could hear a siren but I couldn't see anything, so I thought the cruiser was coming. When it didn't stop I realized something was wrong," said Biagotti.

The Middlesex County Sheriff’s office released a statement saying, “We know the work of correction officers is difficult and dangerous, but that does nothing to ease the pain and shock when we lose one of our own.”

The officer conducted routine perimeter checks at the Middlesex House of Correction in Billerica. State police continue to investigate the crash.
