Authorities say a father is charged with killing the driver of a car that hit and injured his 4-year-old son in Cincinnati, the AP reports. Twenty-four-year-old Jamall Killings turned himself in Tuesday. A judge set bond Wednesday at $2.1 million on murder and felonious assault charges. Killings' son was struck March 24. His injuries weren't life-threatening. Police are seeking a second suspect in the death of the driver, Jamie Urton. He was shot repeatedly when he got out of his car and apparently became involved in a confrontation. In the resulting 911 calls, a man identifying himself as Killings is heard giving contradictory information, including saying he killed the driver and then saying someone else shot him.
