How agents hunt for fraud in trove of Medicare data

Eleven armed FBI agents crept around a stone-and-glass Hollywood Hills, Calif., house just before dawn. An AR-15 rifle and four other guns were registered to the man in the house. He was no drug lord. The target was a doctor who moonlighted as a movie producer. The Justice Department charged Dr. Robert A. Glazer with writing prescriptions and certifications resulting in $33 million in fraudulent Medicare claims.
