An 18-year-old Methuen woman was killed early Saturday night and her 19-year-old passenger seriously injured after the car they were riding in rolled over on I-495 in Haverhill.
Alexis Spartz died after the 2004 Lincoln LS sedan she was driving overturned around 6 p.m., on the northbound side of highway, south of the Main Street, Route 125, exit, according to a statement from Massachusetts State Police Sunday morning.
Spartz and her passenger were trapped in the car. An off-duty Methuen firefighter was able to remove the driver and begin emergency medical treatment. Two off-duty state police officers also provided aid at the scene. The passenger was taken from from the car by members of the Haverhill Fire Department.
Both were taken by ambulance to Lawrence General Hospital for treatment. Spartz was later pronounced dead while the passenger was taken to Tufts Medical Center for further treatment.
Police said the cause of the crash is being investigated by the State Police Collision Analysis and Reconstruction Section and Crime Scene Services Section.
