An office manager for Dr. Farid Fata, the Michigan oncologist convicted of misdiagnosing hundreds of patients to defraud Insurance companies revealed details of how staffers helped expose the doctor's crimes. George Karadsheh, who worked for Dr. Farid Fata's Crittenton Cancer Center in Rochester Hills, Michigan, said he started asking questions after staffers kept leaving the practice. When Karadsheh learned that a different oncologist in the practice was quitting, he said the doctor told him it was because Fata was administering chemotherapy to patients who didn't need it. In 2013, after Karadsheh found out what was going on, he spoke to the U.S. Department of Justice. On Aug 6, 2013, FBI agents arrested Fata and stormed the Crittenton Cancer Center.
