PHOENIX (AP) - Authorities in Arizona say they are considering criminal charges if the mother of an 11-year-old girl with leukemia doesn't return her to a medical facility.
Phoenix police say the girl, Emily, had been receiving chemotherapy at Phoenix Children's Hospital.
Police say an infection forced doctors to amputate her arm and insert a device to deliver medications.
The child's mother removed her from the hospital Wednesday night.
Authorities say the girl is at great risk for a deadly infection.
Police are seeking information on the whereabouts of the mother - Norma Bracamontes.
Phoenix police Sgt. Steve Martos says criminal negligence charges could be sought against her, but their first priority is getting the child back to the hospital.
