investigation revealed that Semensi’s vehicle continued to accelerate in reverse and traveled over the
curb of the parking spot, over grass, through a curbed driveway, up a grassy hill, through bushes and
over a sidewalk, at which point the vehicle struck Buckley and knocked him to the ground. The SUV
continued across West Elm Street before finally coming to rest against a building. Semensi was
distraught at the accident scene and remained behind to speak with police before she was taken to
Good Samaritan Hospital for treatment of minor injuries.
The Massachusetts Registry of Motor Vehicles suspended Semensi’s license after the
accident and it remains suspended.
The incident was investigated by State Police Detectives in the Plymouth County District
Attorney’s Office, Brockton Police, State Police C.A.R.S. unit and Crime Scene Services.
