KMBC Channel 9 reports that a police spokeswoman says in a release: "A third party caller stated her son was waiting for the bus when he observed a school bus hit a boy (possibly as a pedestrian), then the boy started shooting at the bus. At this time, the caller's son has not been located for additional information. A bus that was in the area was located, but had no damage to it. Officers are looking for a second bus that may have been in the area at the time."
No injuries have been reported, Channel 9 says.
