A young Marine corporal was struck and killed by a car in South Carolina as she tried to help motorists involved in an earlier crash, according to officials.

Erin Rachel Lilleyfogle, 23, had pulled over on US 17 in northern Beaufort County at 7:30 p.m. last Friday after seeing an accident, officials told the Island Picket.

She had “stepped out of [her] vehicle and was walking toward the other collision but was struck before getting there,” South Carolina Highway Patrol spokesperson Lance Cpl. Matt Southern told the paper.

She was pronounced dead at the scene, officials said.

None of the three people in the 1998 Ford Taurus that struck her were injured. No charges have been filed but the investigation is ongoing, Southern told the paper. There was no word on the condition of those she had been trying to help.

Lilleyfogle, originally from Colorado Springs, Colorado, was in the Carolinas as a corporal at the Marine Corps Recruit Depot Parris Island.

She had already been awarded the National Defense Service Medal and Global War on Terrorism Service Medal and was about to be honored again, the depot’s Capt. Bryan McDonnell told the paper.

“She was in the process of being awarded the Navy and Marine Corps Achievement Medal for her numerous contributions to the Depot, which will be awarded posthumously,” McDonnell said in a statement.

“She was vital to daily operations, made a major impact during Hurricane Dorian as part of Task Force Albany, and was the caretaker of the Depot Mascot, Opha May,” he said, referring to an English bulldog.
