The Maricopa County Board of Supervisors is looking into whether it can remove county Assessor Paul Petersen from office after he was indicted last week in an alleged adoption scheme involving women from the Marshall Islands. Supervisor Bill Gates, the board’s chairman, said the supervisors are still seeking additional information from the Maricopa County Attorney’s Office on whether it has the power to remove Petersen. The supervisors have called on Petersen to resign his position, as have county Treasurer Royce Flora, Recorder Adrian Fontes and Gov. There are several state laws that could aid the supervisors if they want to expel Petersen from the assessor’s office. Another statute prohibits county officers from being absent from the state for more than 30 days with approval from the Board of Supervisors.
