Rollover That Killed Waltham Mother Remains Under Investigation

More than two months later, authorities are still investigating the crash that killed a Waltham mother, according to the Middlesex County District Attorney's Office. 

Lisa LeBlanc, 41, died on March 24 when the car she was driving east on Main Street rolled over. Her boyfriend, Bernardo Betancourt, was arrested at the scene and charged with driving under the influence of alcohol.

However, Betancourt has not been charged in LeBlanc's death, according to DA spokesman Stephanie Chelf Guyotte. 

"This crash remains under investigation. These investigations involve multiple agencies completing careful and deliberate work, which generally take months to complete. We have to wait for all of the information in order to make an informed decision," Guyotte told Waltham Patch in an email.

Betancourt, who has a lengthy driving record, was following LeBlanc immediately before she crashed. Police have said Betancourt was "possibly" involved in the crash. LeBlanc's death was later ruled an accident.
