Our investigation started with a tip from an insider at an Ohio State University Hospital. Here's what we uncovered: A homeless immigrant with an expired Green Card, and violent criminal past, making that hospital room his home for more than two years and counting. Our investigation learned Francis Kirton received kidney dialysis a few times a week. It's an expensive out-patient procedure. We wanted to know why Kirton was allowed to literally live at the hospital, who picked up the tab, and why an immigrant with expired papers hasn't been deported. Also, we wanted to know if there were other Francis Kirtons keeping house at Ohio hospitals. Getting answers to those questions was difficult. What we discovered was mind-boggling.
