This summer, a Kansas City man named Edwin got a call from immigration officials. They had picked up his nephew at the southern border and wanted to release the teen into his care. So Edwin went online and bought a bed. Later that week, he was contacted again, this time by an Immigration and Customs Enforcement detective who knocked at his door. The agent gave Edwin a letter saying he needed to come to headquarters for an interview about three federal crimes: conspiracy, visa fraud and human smuggling.
