A couple is being held as "persons of interest" in the death of a 3-year-old girl found buried in a backyard in Thatcher.
Police said the victim's mother, 28-year-old Anna Marie Sanchez and 23-year-old Joshua Cisneros are being questioned.
The girl's older brothers were interviewed by the Department of Child Safety after they were found alone in a hotel room that led police to search the backyard where the 3-year-old girl's body was found.
The boys said their sister had been missing since 2012.
Thatcher is about 160 miles southeast of Phoenix.
