The feds quickly opened a facility in Artesia, New Mexico, with the specific mission of detaining mothers and young children. But that facility drew controversy and closed down before the year was out. Many of the detainees there were then transferred to a new facility in the town of Dilley, Texas. The benignly-named South Texas Family Residential Center, also called Dilley, is a 2,400-bed immigrant detention center that serves as a temporary home—if that’s the appropriate word to use for a place you can’t leave—for mothers and young children.
