MADISON, Wis. (AP) - Two former employees of the band pleaded guilty to embezzling more than $200,000 of the tribe's money. The pair face up to five years in prison. The U.S. Attorney's office in Madison said they were part of a group of employees in the tribe's accounting office that took nearly $1 million since 1991. FBI and Department of Interior agents are continuing their investigation, which may lead to charges against the rest of the group, Assistant U.S. Attorney John Vaudreuil said May 4. Allan F. Butterfield, 63, the band's comptroller and treasurer, and Lou Ann Gordon, 47, lead accountant, were charged in October. Both are from Bayfield. Butterfield pleaded guilty May 3 in U.S. District Court in Madison to embezzling tribal money. Gordon pleaded guilty to the same charge more than a week ago. Butterfield agreed to pay back $108,090, and Gordon agreed to pay back $137,207, Vaudreuil said. A judge will sentence Gordon July 19 and Butterfield July 26.
