PHOENIX - The mystery surrounding the whereabouts of a sick girl with leukemia deepened Wednesday after her father said his 11-year-old daughter is being treated in Mexico and authorities considered bringing child neglect charges against the family.
Phoenix police have been looking for Emily since surveillance video one week ago showed the girl's mother walking her out of Phoenix Children's Hospital a day before the child was set to be released.
Authorities are searching for the girl in Arizona, California and Mexico, where the family has relatives, as doctors say she could contract a potentially deadly infection if not returned for treatment.
The girl underwent about a month of chemotherapy and had been treated for an infection that forced doctors to amputate her arm, police said. Doctors had inserted a tube through her chest to deliver medications through her heart. Her mother unhooked the tubing from an IV and left with the girl, leaving her susceptible to infection.
Phoenix police said the parents could face criminal neglect charges if they didn't return the girl.
U.S. Border Patrol agents stopped the father, Luis Bracamontes, 46, as he crossed into Arizona from Mexico over the weekend, but the man denied any involvement in removing his daughter from the hospital and said he didn't know where she was.
However, in an interview this week with NBC News, Bracamontes said his daughter was safe and being treated by doctors in Mexico.
Bracamontes blames the Phoenix hospital for the loss of his daughter's arm and says the family was being pressured over mounting medical bills.
