North Charleston police have arrested a Moncks Corner woman in connection with a fatal, Monday afternoon hit-and-run at Northwoods Mall.

Helen Ann Williams, a 47-year-old resident of Fairlawn Drive, has been charged with leaving the scene of an accident involving death, police said. She turned herself in to police Tuesday afternoon.

The victim, 45-year-old North Charleston resident Billy Vaughan, died at Roper Hospital Diagnostics and Emergency Room — Northwoods, according to the Charleston County Coroner's Office. He was pronounced dead at 2:31 p.m.

Williams and Vaughan had known each other for more than 10 years, police said. 

Preliminary information about the crash indicates that Williams was driving a U-Haul truck through the mall parking lot, struck Vaughan and continued driving toward Rivers Avenue, police said.

The U-Haul was found in Moncks Corner overnight and Williams was located at a residence in Moncks Corner, with the assistance of Moncks Corner police, North Charleston police said.

A search of Charleston County court and Cannon Detention Center records showed a number of prior arrests for crimes ranging from criminal domestic violence of a high and aggravated nature to public intoxication.

Williams pleaded guilty to second-degree assault and battery, and to her second offense of criminal domestic violence within 10 years on Aug. 12, 2015, according to court records. 

She is expected to appear in bond court on Wednesday, police said. The investigation is ongoing.
