Four children in Arizona have been rescued by authorities after spending years living in horrifying conditions at their adoptive parent's house.
Deputies were only notified to the scene when one of the kids climbed through a window and went to a nearby shop to use the phone.
Police say a worker "noted the age and dishevelled condition of the child" and called for help.
It was then the horrifying living conditions were discovered.
The kids, aged between six and 12, were kept in locked, dark rooms with no food, water or toilet access for up to 12 hours at a time, Pima County Sheriff's Department says.
One bedroom had only a bucket as a toilet.
Benito Gutierrez, 69, and Carol Gutierrez, 64, are facing charges of child abuse. The children have been removed from the home and the investigation is ongoing.
Last month 13 children were exposed living in disturbing conditions in their Californian home, facing beatings, shacklings and abuse for up to two years.
The parents, who have been charged with multiple counts of torture, child abuse and false imprisonment, gave little food to their children, ranging in age from two to 29 years old, according to prosecutors.
The case is still before the courts.
