BANGOR, Maine — A 57-year-old woman who was seriously injured early Saturday when she was struck by a car and who later died at the hospital has been identified as Brecon Oldham of Bangor.

Oldham was out on a walk near the highway overpass on Union Street about 7:45 a.m. Saturday when she was struck by a car driven by Bangor resident Marie McBrine, 78, Bangor police Sgt. Paul Edwards said Monday morning.

“When officers arrived at the scene, there was at least one volunteer firefighter from a local area department who had stopped and assisted,” the sergeant said. “Oldham was transported to Eastern Maine Medical Center and later died from injuries sustained from the accident.”

Oldham was attempting to cross an onramp for Interstate 95, Sgt. Ed Potter said Sunday afternoon.

“It was in a crosswalk on Union and [I-95] and the [driver] was making a turn,” Potter said.

McBrine had her 6-year-old granddaughter with her; neither were injured, Edwards said.

Police are still investigating who had the right-of-way — if the driver had the light or if the pedestrian had a signal to walk — when the deadly collision took place, Potter said.

“I’m not anticipating charges at this point,” Lt. Tim Reid, the department’s lead detective, said early Sunday.

The incident is still under investigation, and police are looking for witnesses and others who have information, Edwards said. Those with information about the ongoing investigation can call the Bangor Police Department at 947-7382. The department’s anonymous tip line can be reached by pressing extension 6.
