HEBER SPRINGS, Ark. -- A former boyfriend of Mindy McCready says someone made a "big mistake" in releasing her from an inpatient substance abuse treatment center.
Billy McKnight says the country singer had threatened to kill herself after losing custody of one of her sons earlier this month -- yet she was allowed to leave the court-ordered rehabilitation program just days before she apparently took her life.
Her shooting death came at the same spot -- the front porch of her Arkansas home -- where her boyfriend died last month of a gunshot wound to the head. That death is also being investigated as a suicide.
Cleburne County Sheriff Marty Moss said Monday that it appears McCready killed her late boyfriend David Wilson's dog before she turned the gun on herself Sunday. The dog and McCready were found dead next to one another.
