FREETOWN — Authorities have released the name of the woman killed in a Friday morning crash on Route 140 in Freetown.

The Bristol County District Attorney's Office says the 18-year-old North Dartmouth woman has been identified as Savannah Gonsalves, who died as a result of the fatal one-car rollover crash on Thursday morning.

At around 8:10 a.m., Gonsalves was traveling northbound on Route 140 in the area of Exit 8 in Freetown in a 2003 Ford Escape. For reasons still under investigation, Gonsalves appears to have lost control of the vehicle, traveled into the median and then rolled over and crashed on the southbound side of Route 140, coming to rest in the breakdown lane.

Gonsalves was ejected from the vehicle during the rollover and pronounced dead at the scene by a lieutenant with the Freetown Fire Department at 8:15 a.m.

The fatal crash remains under investigation by the Massachusetts State Police Collison Analysis and Reconstruction Section, Crime Scene Services Section, Troopers assigned to the Bristol County District Attorney’s Office, and the Office of the Chief Medical Examiner.

State Police were assisted on scene by Freetown Fire and EMS, Freetown Police, and MassDOT.
