A Dartmouth woman was seriously injured and her passenger was killed in a one-car crash in New Bedford on March 28, according to a press release from the Bristol County District Attorney’s Office.

The driver — a 21-year-old Dartmouth woman whose identity was not disclosed — sustained serious injuries and was rushed to Rhode Island Hospital, according to the release.

She remains in serious but stable condition.

Front seat passenger Tierrah Martinez, 20, of Fall River was declared dead at the scene.

New Bedford Police and Massachusetts State Police are currently investigating the crash, which took place at around 2 a.m. Sunday morning on Route 18 near the intersection with Walnut Street in New Bedford.
