A car hit and killed a Marine corporal from Colorado Springs, Colorado, on Oct. 11 in South Carolina while she was stopped to help someone who had been in an earlier crash, officials said.

Erin Rachel Lilleyfogle, 23, was pronounced dead at the scene, said Beaufort County Deputy Coroner David Ott, The Island Packet reported. She was a corporal at the Marine Corps Recruit Depot Parris Island, in Port Royal, South Carolina.

Lilleyfogle “had stepped out of (her) vehicle and was walking toward the other collision but was struck before getting there,” South Carolina Highway Patrol representative Lance Cpl. Matt Southern told The Packet.

The crash took place at 7:30 p.m. on U.S. 17 near Jenkins Road when a 1998 Ford Taurus struck Lilleyfogle. The people inside the vehicle were uninjured, Southern said.

Lilleyfogle joined the Marines in March 2017, and served as a non-commissioned officer in charge of the Headquarters and Service Battalion’s administrative section, Capt. Bryan McDonnell, director of Communication Strategy and Operations at Parris Island, told The Packet in a statement.

Lilleyfogle was previously awarded the National Defense Service Medal and Global War on Terrorism Service Medal, according to McDonnell, and “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.”

The crash is still under investigation. No charges have been filed yet.
