In another sad development in the life of Mindy McCready, the troubled country singer has reportedly been committed to a treatment facility, and her children have been placed in protective care by authorities in the state of Arkansas.

The move comes just weeks after the death of McCready's boyfriend, David Wilson. That was initially reported to be a suicide, but subsequent reports have stated that McCready may be under investigation for her possible role in Wilson's death. McCready has not been named as a suspect, and police have not yet made a formal determination as to Wilson's cause of death. McCready has emphatically denied any involvement.

McCready's ex-husband, Billy McKnight, recently filed for full custody of their six-year-old son, Zander. McCready had only recently gained custody of Zander before Wilson's death. E! News reports that both Zander and Zayne -- McCready's infant son with Wilson -- are currently in the custody of the Department of Human Services in Arkansas after a judge ordered the 'Ten Thousand Angels' singer committed to a treatment facility for alcohol abuse and a psychological evaluation.

"Family members sought to have Mindy committed to a mental health facility, and there was an emergency hearing today," a source says. "They just got out of court a little while ago and the judge committed her for up to 21 days." Another source adds that McCready has admitted to drinking to cope with Wilson's loss, but continues to deny any involvement in his death.
