Arrow Trucking may owe between $2.25 million and $5 million in unpaid civil damages and medical claims the company let pile up while it was in business

, according to reports by the Tulsa World.

Through talking with former claims workers for the company and former employees, the publication found that Arrow had been denying claims without cause and letting unpaid claims sit, while injured workers received no treatment.

Since ceasing operations Dec. 21 with no prior warning, Arrow has been hit by financial and legal troubles, including two class action lawsuits filed by employees who seek damages, and three lawsuits filed against CEO Doug Pielsticker by banks. Arrow was also sued by its main creditor, Utah-based Transportation Alliance Bank, alleging fraud and racketeering.

In early January, the carrier also filed for Chapter 7 bankruptcy liquidation.

"It did not surprise me that they went belly up," Attorney Scott Ash told the World. Ash represents several former Arrow workers.

"Toward the end, they were not doing much of anything. One of my clients' checks bounced, and they were really not authorizing surgeries or taking action on claims."

Joseph Mowry, former executive vice president of Arrow, told the World Arrow was self-insured and processed workers compensation claims itself. The company also handled claims for liability and cargo damage filings in-house.

Mowry told the publication that the carrier would pay out claims when the Finance Department had the cash flow available. This usually included the most urgent claims.
