Boise Police says Sara Ball of Boise has been charged with felony desertion or nonsupport of a child after she left the infant alone in a bedroom Dec. 2.
BPD was notified by a homeowner who told police that Ball did not tell the calling party that she was leaving the child and did not leave diapers or food for the child.
Since that time, BPD says Ball has refused to pick up the child or provide for the child's needs. The child was later turned over to the custody of the Idaho Department of Health and Welfare.
Ball turned herself into authorities Monday evening.
