Clara Bergan, 7, killed and Kayla Eherlico, 14, seriously injured in backyard pool swing accident in Gilbert, Arizona

The accident occurred in the backyard of a home near Higley and Queen Creek roads around 9:30 a.m. Sunday in Gilbert. Authorities say a 14-year-old girl was swinging on a large wooden rope swing near the corner of the pool deck when the swing broke, knocking the teen into the pool. As she fell, she accidentally knocked a 7-year-old girl into the pool with her. Both girls sustained serious head injuries. The younger girl was found at the bottom of the pool, and the homeowner, who is a doctor, attempted CPR to revive her, but she was pronunced dead. The teen was brought to Phoenix Children’s Hospital where she underwent surgery for head and shoulder injuries, but she is expected to survive.
