The results are in from Mindy McCready 's preliminary autopsy, and the Arkansas Crime Lab confirms the troubled singer committed suicide with a single gunshot wound to the head. McCready shot herself and her dog February 17 on the front porch of the Heber Springs, AK home she once shared with fiancé David Wilson . He died January 13 possibly of a self-inflicted gunshot wound, though there's been no official determination of his cause of death and both deaths are still under investigation.
McCready's two sons, Zander and Zayne , have been in foster care since February 7 when authorities removed them from McCready's care.
