CLEVELAND, Ohio — The NAACP on Thursday demanded an explanation from Cleveland Police Chief Calvin Williams, who issued no discipline to a supervisor for detaining Tamir Rice’s sister in the moments after a police officer fatally shot her 12-year-old brother.

NAACP Cleveland President Danielle Sydnor said her organization “expresses its grave disappointment and anger”over Williams decision to issue no discipline to Sgt. Jannelle Rutherford despite a recommendation from the Cleveland Civilian Police Review Board to suspend the officer without pay for six to 10 days.

Sydnor said the NAACP demands an “immediate” explanation from Williams and for Public Safety Director Michael McGrath to support the civilian review board’s recommended punishment.

“What message does it send to the community when future complainants seek accountability for law enforcement if complaints are filed, and a recommendation for discipline is made by the CRPB, but it is overturned by law enforcement leadership?

Messages left with Cleveland police spokeswoman Sgt. Jennifer Ciaccia were not immediately returned. Ciaccia previously declined to release more information on Williams’ decision and referred a reporter to make a public records request, which has not yet been filled.

Fraternal Order of Police President Capt. Brian Betley previously told clevleand.com that Williams dismissed Tajai Rice’s civilian complaint because Rutherford was not named in the complaint and because she was only in charge of the crime scene for a short time before higher-ranking superiors took over.

Tajai Rice was inside the Cudell Recreation Center when former Cleveland police officer Timothy Loehmann fatally shot Tamir. She ran to the scene, was confronted by police officers and detained for 64 minutes in the backseat of a cruiser that sat about 10 feet away from her dying brother.

“Samaria Rice is no longer shocked by the unwillingness of the police chief to hold anyone accountable,” Rice family attorney Subodh Chandra said in a statement. “But she is disappointed.”
