Federal investigators amassed evidence that Fata had bullied or deceived 553 people into getting chemotherapy treatments they didn't need, leaving the patients' insurance companies and Medicare stuck with $34 million in fraudulent and unnecessary claims. They also found that Fata took kickbacks from two local hospices, and poured Medicare and private insurance proceeds into his own diagnostic testing facility, where he ordered unnecessary diagnostic tests. On the basis of these findings, Barbara McQuade, the United States Attorney for the Eastern District of Michigan, won a series of superseding indictments against Fata.
