On the night of June 18, the FBI received another call from the kidnappers for a ransom drop. However, the agents arrived at the drop-off location too late; the chief then received a call from the kidnappers trying to work on an alternative plan. During that call, an agent noticed a man picking up a public phone wearing latex rubber gloves. Suspicious, she took down his license plate number as he drove off. The FBI learned that the car belonged to a nearby rental-car agency. Despite the fact the agency was already closed, the owner agreed to meet up with them, whereupon the FBI learned that the car had been rented to someone named Arthur Seale. Seale arrived in that car soon after, while the agents were still present, and was arrested. Irene was also arrested when she arrived at the shop within minutes.
