"BLANCHARD, Okla. – Authorities don't plan to file charges against an Oklahoma woman who fatally shot a New Year's Eve intruder at her house while she had a 911 dispatcher on the phone, but the intruder's alleged accomplice has been charged in the death. A 911 tape released to Oklahoma City media outlets Wednesday reveals that 18-year-old Sarah McKinley asked a Grady County dispatcher for permission to shoot the intruder. McKinley's 3-month-old son was with her when she shot Justin Shane Martin, 24, at her Blanchard mobile home. "I've got two guns in my hand. Is it OK to shoot him if he comes in this door?" McKinley asked the dispatcher. "Well, you have to do whatever you can do to protect yourself," the dispatcher is heard telling McKinley. "I can't tell you that you can do that, but you have to do what you have to do to protect your baby." Oklahoma law allows the use of deadly force against intruders, and prosecutors said McKinley clearly acted in self-defense. According to court documents, Martin was holding a knife when he died." .
