The scam is estimated to have cost the industry approximately $80 billion a year.

Miami-Dade State Attorney, Katherine Fernandez-Rundle, says the loss totals to more than the annual salaries for millions of American families. Also, the scam is responsible for raising the rates on local auto and homeowners insurance policies.

According to the latest crime statistics, Miami-Dade is currently on track to beat out the Tampa/St. Petersburg area for the worst rate of insurance fraud in the state.
