According to the Ozark County Times, Savannah's mother gave her up for adoption at birth but was still in contact with her as well as the adoptive parents, who lived in Park Rapids, Minnesota.
About a year ago, Savannah went to live with her biological mother in Longrun, Missouri, because of "problems she had at home" in Minnesota, include issues related to autism, the paper says.
When she was reported missing in July, authorities initially thought she might have run home to Minnesota to be with family members.
But on Wednesday, Aug. 9, Ozark County authorities found charred bones while executing a search warrant on her mother's property.
On Monday, the local sheriff confirmed the remains as those of the missing girl.
According to the Star Tribune, jail records show Savannah's mother has now been taken into custody.
