A woman who ran a Long Beach, CA, company called International Commercial Insurance has been sentenced to more than four years in prison for allegedly defrauding five trucking companies.

According to a California Department of Insurance press release, 44-year-old Yvette Diaz and a coworker took more than $13,000 in premiums from truckers, then kept the money and issued bogus proof-of-insurance documents.

The coworker was ordered to do 30 days of community service.
