Police in North Carolina say a 9-year-old girl has been fatally shot and three others have been injured following a shooting at a residence in southwest Charlotte.

Deputy Chief Jeff Estes of the Charlotte-Mecklenburg Police Department said during a news conference that the shooting happened just after 9 p.m. Saturday while a family celebration was ongoing in the front yard.

The unidentified 9-year-old girl died at a hospital. Two adults and another child suffered non-life-threatening injuries and were treated at the scene.

Estes said: "We have a lot of soul searching to do when as a city, and as a country, a 9-year-old girl isn't safe playing in her front yard."

No motive has been determined.

Police are investigating and asking anyone with information to call Crimestoppers at 704-334-1600.
