Pima County Sheriff's Department in Tucson is investigating after four children ranging in age 6 to 12 years old were discovered living in unsanitary conditions inside of the home of their adoptive parents.
Authorities declared that the Tucson couple was taken into custody shortly after one of the children escaped the house and sought refuge in a nearby convenience store.
An Arizona couple has been charged with allegedly abusing their four adoptive children and holding them captive.
Noticing the boy appeared young and "disheveled", the clerk instead called 911, according to a Pima County Sheriff's Department press release obtained by ABC15.
During the investigation, deputies learned that the children were kept in separate bedrooms that were locked from the outside, and regularly did not have access to food, water, lights or a bathroom for up to 12 hours at time, according to the release.
One of the children escaped through a bedroom window and went to a local business, asking to use a telephone.
The children have since been removed from the house.
When officers rushed to the house they found that the children, who were aged six to 12, had been locked away in separate bedrooms.
They are held in jail on a $25,000 bond. The Turpin children range in age from tow to 29.
Gale Kelley, a trainer for the International Association of Trauma Professionals, said children in these cases often are not aware of the fact that they have been abused.
