Mindy McCready's children: What will happen to her sons?

Mindy McCready: 1975-2013

The popular country singer led an often troubled life.

Mindy McCready was known to the world as a talented country music star plagued by personal demons. But at home, McCready was a mother to two young sons—Zander, 6, and Zayne, 10 months.

Shortly before McCready’s death from a self-inflicted gunshot wound on Sunday, the boys were taken away from the singer and placed into foster care while she entered court-ordered rehab.

Her father, Timothy McCready pleaded with a judge to send the singer to rehab, filing papers that claim she wasn’t properly caring for the children.

And from reports on the state of McCready’s home he may have been correct. A police source told People magazine McCready’s home was filthy and filled with food, dog feces and prescription pill bottles.

Now that McCready has died, the fate of her two boys is seemingly up in the air.

On Monday, Zander’s father Billy McKnight told the Associated Press he was working with authorities to get his son out of foster care.

McCready's rep Kat Atwood told FOX 411 both boys were still in foster care as of late Wednesday. She said they were in good hands "where they are comfortable and loved."

For McCready's youngest son Zayne, things appear to be complicated. The infant’s father, David Wilson, seemingly committed suicide in January, though an investigation into his death is still ongoing. Wilson’s death left McCready devastated, she told the “Today” show in an interview a few weeks after Wilson had died.

“I’ve never gone through anything this painful nor will I ever again go through anything this painful,” the distraught singer said.

Now, with both of his parents gone, it is unclear who will care for Zayne, but McCready’s mother may be a contender, according to People.

The website reported Gayle and Michael Inge, McCready’s mother and stepfather, want custody of both children. The Department of Human Services sent a letter to one of the circuit judges requesting the Inges retain custody of the children, according to People.

The Arkansas Circuit Clerk’s Office, where the custody case is being handled, told FOX 411 there were no new developments in the custody case regarding McCready’s children.

The Department of Human Services did not immediately return FOX 411’s request for comment.
