A western Iowa bank was robbed this weekend, and a suspect from Council Bluffs is already in custody. The Mid-States Bank in Mondamin was robbed just before noon on Saturday. Witnesses say the suspect entered the bank but did not display a weapon, handed the teller a bag and told her to fill it. Forty-three-year-old Ernest Wilcox of Council Bluffs was later arrested in Omaha and he’s being held in the Harrison County Jail. Authorities must now decide whether to charge Wilcox with federal or state robbery charges.
