The other driver honked his horn, and King-Macon honked back, the police report said.
A three-year-old boy who was being taken on a shopping trip by his grandmother was killed in a road rage shooting when a driver opened fire on the grandmother's vehicle because she "wasn't moving fast enough at a stop sign", police said.
Little Rock police Lt. Steve McClanahan said, "Apparently she didn't roll through [the stop sign] fast enough".
The shooting was senseless and unprovoked, police said in a press conference. It was the second time in a month that a young child was fatally shot while riding in a vehicle, Police Chief Kenton Buckner told reporters. The child died in hospital a short time later. The grandmother pulled into a nearby shopping center parking lot where she called the police.
Police are looking for an older black Chevrolet Impala driven by a tall black man. "But this is about as frustrating as you can be as a public safety official or just a plain citizen".
"We can not have a community where the least protected among us, being infants, are dying these senseless crimes in our city", Buckner said.
The child's death is a particularly painful subject for many in Little Rock, who have seen two similar incidents within a month of each other. A reward now being offered for information.
