Three boys from a group home in Walpole, Massachusetts were found and returned safe after they went missing on Wednesday night.
The children, ages 12 and 13, ran off property owned by Home for Little Wanderers around 11 p.m. and were found safe three hours later at a 7-11 store in Walpole.
Police say it's not entirely clear how the youngsters manage to leave the property undetected.
The state's Department of Children and Families is now looking into the incident.
A statement from The Home for Little Wanderes reads in part, "We applaud the diligence and quick action of the Walpole Police in locating and returning our three children. The Home for Little Wanderers plays a parental role to the children who live at our Longview Farm school, and like any parent we took every action necessary to ensure their safety."
