OKLAHOMA CITY - A woman is mauled and killed by a pit bull. According to police, 60-year-old Nellie Davis was found by her granddaughter Wednesday night around 11:30 p.m.

Oklahoma City Police officers responded to a possible domestic call at the Highland Apartments located in the 12700 block of North Penn where they soon discovered what happened. Police say the granddaughter had returned home and found her grandmother had been killed by one of their two large pit bull dogs.

Police say officers attempted to contain the vicious animal in a large plastic animal crate, where it was housed prior to the attack. The dog had broken the crate lock and attacked Davis. An officer was forced to shoot the dog when it continued to attack and all attempts to contain it had failed.

Homicide detectives are investigating the victim's death while patrol supervisors investigate the shooting of the dog.
