Authorities said Monday that the co-owners of the family business Diaz Supermarkets were involved in $35 million in fraudulent transactions. The scheme that the Diazes were allegedly involved in is popular in the contractor world, Alexopoulos said. Subcontractors are required to show proof of workers’ compensation coverage and they find ways around it.

Authorities seized $640,000 and three vehicles, Atwater said. Former employees said authorities raided and closed four stores Friday: Two were in Homestead at 1215 NE Eighth St. and 212 W Mowry Dr. One was in Naranja at 13501 Moody Dr., and another was at 151 Opa-locka Blvd., in Opa-locka.
