The woman accused of torturing two young children who were later killed and dumped in rural Mississippi and Alabama is expected to return to Alabama to face charges.

Heather Leavell-Keaton was to return to Mobile on Sunday, a day after search teams found remains that police believe belong to one of the children.

Police said search teams found the skeletal remains near a county road in Citronelle, about 30 miles north of Mobile.

Investigators believe the remains belong to Natalie DeBlase, who would have turned 5 in late November. Skeletal remains found Wednesday in Mississippi are believed to belong to her 3-year-old brother, Chase.

The children's father, 27-year-old John DeBlase, is charged with murder and corpse abuse.
