An abandoned bicycle for children, a baby swing and rubbish are seen in the back patio of a house seized by authorities in Ciudad Juarez May 23, 2014. The house was seized and sealed after it had been identified as one of a series of safe houses for illegal immigrants used by a group of coyotes, according to police reports. Police found the house after arresting a coyote who was with 12-year-old Ecuadorean girl Nohemi Alvarez Quillay, on a street in Ciudad Juarez. She was travelling with the coyote after her parents, who live in the U.S., paid a group of coyotes to bring her over. She was later sent to a government-run shelter for her protection where she committed suicide shortly after. Tens of thousands of children unaccompanied by parents or relatives are flooding across the southern U.S. border illegally, forcing the Obama administration and Congress to grapple with both a humanitarian crisis and a budget dilemma.
