The former chief executive of a Pennsylvania company that made concrete bridge beams has been convicted on multiple counts of fraud and money laundering in what the U.S. Dept. of Transportation says is the largest reported Disadvantaged Business Enterprise fraud in the department’s 45-year history.

The Justice Dept. said a jury in U.S. District Court in Harrisburg on April 5 found Joseph W. Nagle guilty on 26 of the 30 charges in a federal indictment. Nagle (pronounced  NOGG-ull) was president, CEO and part-owner of Schuylkill Products Inc. (SPI), Cressona, Pa., and its CDS Engineering Inc. subsidiary until 2009 when the parent SPI was sold.
