Mindy McCready died of an apparent self-inflicted gunshot on the same porch where her boyfriend died, and sources tell TMZ she shot the family dog before taking her own life. The troubled country singer, who was found dead at her Arkansas home yesterday, recently told an interviewer that the dog had found the bullet that killed boyfriend David Wilson in another apparent suicide last month, the Daily Mail reports. "I didn't find the bullet, the dog did," she said. "It was in the dog's mouth." She firmly denied any involvement in the death of Wilson, the father of the younger of her two sons, but the probe into his death is ongoing, the local sheriff tells the New York Daily News.
