June 2009, North Las Vegas, Nevada.

Two-year-old Everlis Cabrilla was put to bed by her foster parents one summer evening.

Nothing seemed out of the ordinary. The next morning,

when they went to wake the toddler for breakfast, she was nowhere to be seen. The front door was

and cocaine soon after birth. Because of this, and because they didn't have stable housing for the

babies, Evelees and Benjamin were removed from their care, the children

bouncing from Child Haven to a temporary shelter home to foster care.

Anisto and Marlina ordered to secure suitable housing before it would even be a consideration

to regain custody of their children.
