Two children were killed and at least 10 people injured, including other children, on Monday in a multi-vehicle crash involving a stolen police car in Dayton, Ohio, police said. The crash began with a reported stabbing in Dayton, police said, and a pickup truck accident in the Dayton suburb of Riverside at about 7:30 p.m. Apparently, the suspect in the reported stabbing fled that scene and then crashed the pickup, police said. While Riverside police were looking for the driver of the crashed truck, the suspect, who was still on the scene, jumped into a Riverside police sports utility vehicle.
