DES MOINES — A Sioux City man has agreed to turn state’s evidence and pay $100,000 in restitution to the state in exchange for charges against him being dropped.
Grady Marx, 60, is one of three men involved in what state investigators said was a $500,000 money-laundering and kick-back scheme involving Iowa Department of Transportation land sales and contracts.
Authorities claimed his co-conspirators were the father-and-son team of David and Jason Weigel of Nevada.
On Wednesday, Iowa Assistant Attorney General Robert Sand filed papers in Polk County District Court dismissing the charges against Marx.
“The parties have reached an agreement under which the defendant will cooperate in pending related prosecutions of other individuals, provide evidentiary material to the state and pay $100,000 in restitution,” the document read.
Attorney General spokesman Geoff Greenwood said the charges against the Weigels — both were accused of multiple felonies in connection with the alleged scheme — will go forward.
"I am thrilled to be exonerated of the charges, and I'm very thankful for the support I've received from my family and friends," Marx said in a news release sent Wednesday by his attorney, Todd Lantz.
David Weigel is accused of using his position as an Iowa Department of Transportation right-of-way agent to enrich himself. Marx, who owns a Sioux City transportation company, was accused of helping Weigel further his schemes.
Both were charged in April with theft, conspiracy to commit theft, money laundering and criminal conduct. Jason Weigel was charged as a participant in the scheme in July.
"This is a terrific outcome for Mr. Marx and the state of Iowa," Mark Weinhardt, one of Marx's attorneys, said in the news release. "In many criminal cases, the facts are more complicated than the initial reports, and it takes time for those facts to come to light."
