After country singer Mindy McCready committed suicide on Sunday, a question came to the forefront: where will her two young sons, Zander, 6, and Zayne, 10 months, go?

Shortly before McCready's death of a self-inflicted gunshot wound, the boys were taken away from the singer and placed into foster care while she entered court-ordered rehab, Fox News reported.

Timothy McCready, Mindy's father, insisted that the judge send his daughter to rehab, filing papers that she wasn't properly caring for her children.

He may have been right, because a police source told People magazine McCready's home was filthy and filled with food, dog feces and prescription pill bottles.

After McCready's death, the fate of her sons is completely uncertain. Zander's father Billy McKnight told The Associated Press he was working with authorities to remove his son from foster care.

 "My son needs me," McKnight told People on Feb. 8. "I'm married, working and successful. I'm on the right track and proud of it. I've been sober for years. I just want my son." 

But matters are more complicated for Zayne, whose father, David Wilson, apparently committed suicide in January, although the investigation into his death continues, Fox News reported.

"I've never gone through anything this painful nor will I ever again go through anything this painful," McCready said after Wilson's death.

McCready's mother and stepfather also want custody of both children - and authorities appear to be on their side, People reported.

In a proposed order sent to Circuit Judge Lee Harrod, the Department of Human Services stated that the Inges might be a better fit for Zander and Zayne, because of their "substantial relationship." The Inges had custody of Zander during many of the past few years, while McCready spent time in rehab and jail.

A custody hearing has been scheduled for April 5 - when the judge will determine what housing situation is in the children's best interest.
