Appearing in a Phoenix court, Frank Ruiz admitted to paying more than $1 million in kickbacks to an AEA vice president of business lending, also charged in the case, to obtain $22 million in loans to finance a Yuma kids park and nightclub, both of which went bankrupt.   

In the plea deal, Ruiz has agreed to testify against William Liddle, the AEA vice president, and his wife, Rhonda, both of whom face criminal charges in a trial set for next January.
