A federal grand jury in Kentucky had indicted three people with various trucking companies on charges they attempted to defraud customers.

Elliot C. Campbell, Melinda J. Campbell and Bryan Napier face charges that include wire fraud and conspiracy to commit extortion. Some of the charges carry a maximum possible sentence of 20 years.

They reportedly controlled or operated several trucking companies, including Interstate Lines Inc., West Coast Trans Inc., and Zink Inc., which bid on interstate freight-hauling jobs online, according to a report from Kentucky.com.

According to the indictment, the contracts their trucking companies made with customers often called for them to be paid only after the shipments had been delivered, however, the three are alleged to have held shipments after pick-up, threatening to withhold delivery until payment was received.

When complaints were filed against the trucking companies, mainly by freight brokers, the three would allegedly form new trucking companies with different names in order to continue doing business.
