CHARLOTTE, N.C. — Detectives say a North Carolina woman killed her two children and then jumped off a bridge onto an interstate highway to kill herself.

The Charlotte-Mecklenburg Police Department says they were called early Saturday evening after the woman dropped onto the asphalt on Interstate 485. Officers say 34-year-old Christina Elizabeth Treadway was dead at the scene.

Police say they went to the woman’s home and inside found two children suffering fatal wounds. Treadway’s 3-year-old-daughter, Iliyah Miller, and 7-year-old son, Isaiah Miller, died at a hospital. No one else was inside the home.
