BROCKTON – A Pembroke woman will be arraigned tomorrow 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.

Danielle Mastro (DOB: 04/14/84) of Pembroke, was arrested this evening and charged
with one count each of Motor Vehicle Homicide and Leaving the Scene of an Accident.
At approximately 3:30 pm today, 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 at 2:41 pm. She is not being identified at this time, pending
notification of next of kin. The female passenger in the 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.
Investigators interviewed Mastro and obtained a warrant for her arrest this evening. She
is scheduled to be arraigned tomorrow in Brockton District Court.

The crash remains under investigation by State Police Detectives assigned to the
Plymouth County District Attorney’s Office, Brockton Police and the State Police CARS Unit
and Crime Scene Services.
