Florida Attorney General James Uthmeier issued civil and criminal subpoenas Thursday to White Hawk Carriers, the trucking company that employed an illegal immigrant involved in the fatal freeway crash that killed three people in August.

The Aug. 12 vehicle crash made national headlines after authorities identified the White Hawk Carrier-employed driver as an illegal immigrant who could face homicide charges for the crash. Transportation Secretary Sean Duffy announced a federal investigation into the incident.
