Kansas City police say one person is dead and six children are critically injured after a car accident that happened amid a gunfight. A seventh person was injured by gunfire.

Sgt. Kari Thompson said in a statement that police believe the occupants of two vehicles were exchanging gunfire Tuesday night when one vehicle struck a nearby uninvolved vehicle.

Thompson says one occupant of the uninvolved vehicle was pronounced dead as a result of the crash. Six children who were passengers in the same vehicle were taken to hospitals in critical condition.

She says an occupant of one vehicle involved in the gunfight was also hospitalized in critical condition.

Thompson tells The Associated Press police have a person of interest in custody.

No identities were released, and no further details were immediately available.
