Nearly a week after she died, a cause of death has not been determined for the Natchez woman who was struck by a vehicle on U.S. 65 south of its intersection with U.S. 84 near Ferriday.

Officials at the Concordia Parish Coroner’s Office said Tuesday they had not determined the cause of death.

Martha Cupit, 50, of Natchez entered the highway near the old Lakeside Ford and Camelot Leisure Living, where she was struck by a southbound pickup truck at about 2 a.m. Thursday.

The driver of the truck, Eric Guillot, 23, 452 Cowan St., Ferriday, called 911 and said he believed he had run over a pedestrian.

Louisiana State Police responded to the call, and Cupit was pronounced dead on the scene by the Concordia Parish Coroner’s Office.

A patient at a local long-term care facility, Cupit reportedly exited the building through a window, reports at the CPSO said.

Guillot was arrested by the CPSO and charged with vehicular homocide, second offense driving while intoxicated and no insurance. No bond was set.

Cupit was the third Concordia Parish pedestrian death on the highway this year.

One Vidalia resident was killed near the Vidalia Family Dollar, and another was killed in front of Wal-Mart several months ago.

Funeral services for Cupit will be Wednesday.
