UPDATE | Cleveland mayor apologizes for billing family of dead boy

CLEVELAND (AP) — The mayor of Cleveland has apologized for the city sending a claim to the estate of Tamir Rice, a 12-year-old black boy fatally shot by a white officer, seeking $500 for transporting the boy by ambulance to a hospital.

Mayor Frank Jackson said during a news conference today that a city attorney was responding to a records request made by the attorney for Tamir's estate. Jackson says the claim was routine, but it should have been red-flagged and never filed in Probate Court.

City officials say Medicaid reimbursed the city $179 in early 2015 for the ambulance ride and the file was closed. Tamir was shot in November 2014 outside a city recreation center while playing with a pellet gun.

A Rice family attorney calls the claim filing "deeply disturbing."
