A trucking broker pleaded guilty to a charge in U.S. District Court that he filed false income tax returns.

William L. Roberts, a trucking broker, was indicted by a federal grand jury on Nov. 19, 1987, for filing false tax returns in 1980, 1981 and 1982. He will be sentenced May 19 at 8:30 a.m., according to U.S. Attorney Brent Ward.

Roberts was released on his own recognizance.

Assistant U.S. Attorney Gordon Campbell said that filing false returns carries a maximum penalty of $100,000 fine and/or three years imprisonment. In addition, Roberts is liable for all back taxes, as well as interest.

At a hearing, Campbell said the government was prepared to present evidence that Roberts failed to report gross receipts of $470,000 from Gene's Brokerage and B&B Brokerage for 1980. Roberts filed a return saying that all income was reported on his 1980 tax return. The fine was increased to $250,000 shortly after Roberts' filing.

The case was investigated by special agents of Salt City District of the Internal Revenue Service.
