The death of a 69-year-old woman assaulted at an Oklahoma City City nursing center by another patient is being investigated as a homicide, police reported.

Carolyn Irene Rutledge, 69, died after she suffered a head injury Saturday in the cafeteria at Fairmont Skilled Nursing Center, 3233 NW 10, police reported.

A nurse told police that a 76-year-old patient became angry when Rutledge told him he had a bug on his clothes. He slapped her and shoved her, causing her to fall and hit her head on the floor, according to a police report.

Rutledge was taken to Integris Baptist Medical Center where she was treated for a traumatic brain injury. She died Tuesday, police reported.
