A fourth official of Adams Produce Co. has been charged in a scheme to defraud the federal government.

The week of June 24, the U.S. Attorney’s Office for the northern district of Alabama charged Stanley Butler, a former purchasing agent for Birmingham, Ala.-based Adams, which is out of business, according to a news release from the Birmingham-based attorney’s office.

Butler was charged in a scheme to defraud the government of $481,000. Also the week of June 24, he agreed to plead guilty to the conspiracy charge and, along with co-conspirators in the case, to pay $481,000 in restitution to the government.

The suit charged that Butler defrauded the government’s Defense Supply Center Philadelphia, one of Adams’ customers.

Scott Grinstead, David Kirkland and Christopher Pfahl are the other former Adams officials in the case.

In April, Grinstead, the company’s former chief executive officer, pleaded guilty to four federal charges in relation to fraud and failure to file personal income tax returns. He faces up to 25 years in prison.

Adams filed for bankruptcy and closed in April 2012.
