Authorities on Monday confirmed the identity of a woman killed in a rollover crash early Sunday morning in Waltham.
Lisa A. LeBlanc, 41, of Waltham was killed when her car rolled over near 1163 Main St. on Sunday, March 24, around 12:37 a.m., according to Middlesex County District Attorney's Office Spokesman Stephanie Chelf Guyotte.
LeBlanc was driving east on Main Street when her car veered into the westbound lane and struck another vehicle. Police believe LeBlanc was not wearing a seatbelt at the time of the crash, and that speed was a factor, according to Waltham Police Sgt. William Gallant.
The crash remains under investigation, according to Guyotte.
