In a civil RICO suit that accused three doctors of operating a fraud mill that sharply inflated the costs of medical care for car accident victims, a federal jury last week awarded more than $15.4 million to State Farm Mutual Automobile Insurance Co.

After a three-week trial before U.S. District Judge Eduardo C. Robreno, the jury on Thursday awarded State Farm more than $4 million in compensatory damages and $11.4 million in punitive damages.
