A 63-year-old Milwaukee man is in custody and facing charges of armed robbery after allegedly robbing the same Greenfield credit union twice in just over eight months.

John Macomber was arrested near the Southridge Mall parking lot by the Greenfield Police Department on Dec. 29, shortly after allegedly robbing the Credit Union Service Center just off of 60th Street and Layton Avenue.

According to the criminal complaint, Macomber entered the credit union, pointed a handgun at the teller and said, “Be good, cash.”

Upon hearing from the teller the credit union had been robbed, another bank employee ran out the main door and observed Macomber get into his vehicle. She then yelled out that the bank had been robbed, and upon hearing this, two nearby customers followed Macomber, who had made off with nearly $5,000, to the Southridge area and called the Greendale Police Department.

After the Greendale and Greenfield police departments located Macomber and his vehicle, they arrested him and found a handgun located under the driver’s seat. It was loaded and there was one round in the chamber.

During questioning, Macomber admitted to robbing the credit union of approximately $6,000 on April 22, using the same handgun he used Dec. 29.

Macomber faces up to 40 years in prison and a fine of $100,000 for each count of armed robbery.
