"Record-breaking numbers of children and teens like Santos caught in the U.S. illegally without a parent or guardian are being swept into a strained and secretive federal detention network. Some 60,000 are expected this year - up from about 6,560 in 2011, according to government estimates. The unaccompanied children are housed in a labyrinthine network of more than 90 state-licensed shelters, foster homes and detention centers that the government describes as "safe havens." Most children are well cared for. But a Houston Chronicle investigation found that youths inside the insular system have quietly suffered abuses by the people paid to protect them." - Susan Carroll, May 25, 2014.
