BROCKTON – A Pembroke woman has been indicted on charges she allegedly caused a fatal car crash that left a Bridgewater woman dead and two others injured, Plymouth County District Attorney Timothy J. Cruz announced.

A Plymouth County grand jury today returned indictments against Danielle Mastro (DOB: 04/14/84) of Pembroke, charging her with one count each of: Motor Vehicle Manslaughter by OUI, Motor Vehicle Homicide by OUI and Negligent Operation, OUI Causing Serious Bodily Injury, Leaving the Scene of a Death, Leaving the Scene of Personal Injury, Leaving the Scene of Property Damage, Use of a Motor Vehicle without Authority, Negligent Operation of a Motor Vehicle, Failure to Stop for Police and Operating After License Suspension.

At approximately 3:30 pm on October 3, 2017, State Police Detectives in the Plymouth County District Attorney’s Office were notified by Brockton Police of a fatal motor vehicle crash at 179 Quincy Street in Brockton. State Police responded, as well as the State Police CARS Unit and Crime Scene Services, and an investigation commenced.

Three vehicles were involved in the motor vehicle crash and a preliminary investigation determined that two females were traveling north on Quincy Street in a Chevy Equinox when they were struck from behind by an Audi A6 being driven by Mastro. The preliminary investigation further determined that the rear-ending impact of the Audi caused the Chevy Equinox to veer into the southbound side of Quincy Street and into the path of a 12-wheel heavy dump truck that was traveling southbound. The impact caused the truck to rollover and lose its load before coming to rest on its side. Mastro exited the Audi A6 and fled the scene on foot, but was located moments later by Brockton Police officers on patrol. The female driver of the Equinox, a Bridgewater woman, was transported to Brockton Hospital where she was pronounced dead of her injuries. She was identified as Deborah Combra (DOB: 06/05/59) of Bridgewater. The female passenger in the Chevy Equinox, a Brockton resident, was taken to Good Samaritan Hospital for treatment.

The driver of the dump truck stopped upon impact and remained on scene. He sustained non-life threatening injuries and was transported to a local hospital for treatment.

Through their investigation and witness statements, it was determined that prior to the crash in Brockton, Mastro drove recklessly through the towns of Hanson, East Bridgewater and Whitman and failed to stop for a police officer in Hanson.

The case is being prosecuted by Assistant District Attorney Russell Eonas and was investigated by State Police Detectives assigned to the Plymouth County District Attorney’s Office, Brockton Police Department, the State Police CARS Unit and Crime Scene Services and the Hanson Police Department.
