The identity of a woman who died after crashing her vehicle Saturday afternoon on Payne Road in Scarborough won’t be released until an autopsy can be completed.

Scarborough police Chief Mark Holmquist said Sunday evening in an email that he anticipates that the the state Office of the Chief Medical Examiner will conduct the autopsy Monday.

Police said the woman was speeding along Interstate 95 southbound at about 12:15 p.m. Saturday when she struck another vehicle. The driver whose car was struck called 911 and followed the woman, police Sgt. Francis Plourd said. The 911 caller said the woman got off Exit 42, struck the guardrail several times and then made a right-hand turn onto Payne Road.

The woman then veered off the road, striking a rock and hitting a utility pole before the vehicle she was driving came to rest, Plourd said. The female driver, who was alone in the vehicle, was pronounced dead at the scene. No other injuries were reported.

Police declined to give the woman’s age or say what kind of vehicle she was driving.

Payne Road was closed between Haigis Parkway and Two Rod Road on Saturday while officials investigated.

The cause of the crash remains under investigation by Scarborough police and fire, the Cumberland County Sheriff’s Department and Maine State Police.
