Gloucester County prosecutors say the charge against 38-year-old Toni Lee Coleman of Swedesboro stems from a crash that occurred shortly after 7 p.m. Sunday night in Mantua.
Coleman's car collided with a vehicle driven by 76-year-old John Steponick of Tabernacle. He and his 74-year-old wife, Katherine Steponick, were both hurt in the crash and were taken to a hospital, where Katherine Steponick died a short time later.
Coleman's bail was set at $100,000.
A telephone number for Coleman could not be found Wednesday, and it was not known if she had retained an attorney.
