Police are urgently seeking information from Dartmouth residents after the victim of last week’s hit and run passed away at Rhode Island Hospital early this morning due to her injuries.

Stephanie Tripp of Fall River was 30 years old when she was struck by a car walking along the side of Old Bedford Road in Westport on May 7.

The suspect was last seen in Dartmouth at the corner of Old Fall River Road and Faunce Corner Road at around 8:30 p.m. that same evening.

Police believe he was driving a gray BMW 3 Series vehicle model from 1999 - 2005, which may have sustained minor damage to its hood, front end and/or front passenger side.

Last Tuesday evening police received a 911 call at 8:15 p.m. to report a crash and a severely injured woman in the area of 288 Old Bedford Road.

When first responders arrived, they located the victim, Stephanie Tripp, face down in the breakdown lane suffering from major injuries.

The victim was rushed to Rhode Island Hospital, where she remained in critical condition until her death this morning.

Tripp was walking along the side of the roadway when she was struck by a BMW.

The male driver exited the car and apparently told a witness he was sorry and didn’t mean to hit the victim.

A witness told the driver to stay on scene, but as the witness was providing aid to the victim, the driver sped off in an easterly direction on Old Bedford Road.

Another witness attempted to follow the suspect’s vehicle, which, according to the witness, was traveling at high speed and passing vehicles using the opposite travel lane.

The witness lost the suspect’s vehicle in the area of Old Fall River Road and Faunce Corner Road in Dartmouth. 

Although officers spoke with several witnesses who remained on scene, there is reason to believe that other witnesses may have seen the crash, the vehicle that struck the victim or may have information about the driver.

If anyone was in the area and saw anything, or has information about this case, they are urged to contact Massachusetts State Police Trooper Phil Giardino at 508-961-1928 or Westport Police detectives at 508-636-1122.
