More than 300 migrant children separated from their parents at the U.S. border are under the care of foster agency Cayuga Centers in New York City. It's the largest provider of care for unaccompanied minors in throughout the state of New York, as well as the United States.

Cayuga has a reputation for runaway children, abuse allegations and frequent police calls at its residential facilities for troubled teens in Auburn, New York, according to Liz Robbins, who reported the story for the New York Times. Local police reported 515 calls about runaways between 2014 and 2017. Robbins says Cayuga ended the programs earlier this year because they weren't lucrative.

She says it's still unclear how 600 unaccompanied minors — including the 300 migrant children — in Cayuga's New York City programs are treated.

"Because the federal government has a contract with Cayuga, they keep it very, very secret," she told WNYC's Sean Carlson on All Things Considered. "So far, all we really know is that kids are in foster families."
