Mindy McCready, who hit the top of the country charts before personal problems sidetracked her career, has died. She was 37.

Waren Olmstead, the coroner in Cleburne County, Ark., said in a statement McCready died Sunday apparently of a single, self-inflicted gunshot wound. An autopsy is pending.

Just last month David Wilson, McCready’s boyfriend

and the father of her 9-month-old son Zayne, was found dead on the same porch where McCready's body was found. His death also was investigated as a suicide.

McCready entered court-ordered rehab earlier this month after her father told a judge she was no longer taking care of herself or her children and was abusing drugs and alcohol. Her sons were put in foster care at the time, but it's not clear where Zander and Zayne were at the time of McCready's suicide.
