PHOENIX (AP) — Police say the family of an 11-year-old leukemia patient whose mother unexpectedly took her from a Phoenix hospital last month has a history of removing the child from medical facilities against the advice of doctors.

The child, Emily Bracamontes, had been receiving chemotherapy at Phoenix Children's Hospital for about a month before her mother removed her on Nov. 28 while she was still being treated.

Since then, Emily's parents have refused to provide police in Arizona with any information on the child's whereabouts or treatment, but her mother and father have asserted in television interviews that she is under the care of doctors in Mexico.

The girl appeared in an interview Wednesday on ABC's "Good Morning America," the first time police have seen her since she was taken from the hospital.

Police say until Emily's parents provide proof the child is safe, criminal charges are still being considered.
