(Cleveland) — Cleveland Police say a dozen supervisors are being disciplined after a chase in which officers fired 137 shots and killed a fleeing driver and his passenger.

Cleveland Mayor Frank Jackson and the police chief detailed the results of the disciplinary review at a news conference Wednesday. One supervisor was fire, two others were demoted and nine others were suspended.

Chief Michael McGrath has said supervisors failed to take control of the 19-mile chase that wound through neighborhoods before ending in a barrage of gunfire.

The county prosecutor is conducting a separate grand jury investigation into possible criminal wrongdoing in the chase last November.

The police union said the shootings were justified because the driver tried to ram an officer. Fraternal Order of Police President Brian Betly says grievances will be filed by all 12 supervisors.
