The two men were summoned for formal questioning on May 29.[33] They asserted that on the night of the murder, they had picked up two women, Edna and May, in Chicago, using Leopold's car, then dropped them off sometime later near a golf course without learning their last names. Their alibi was exposed as a fabrication when Leopold's chauffeur told police that he was repairing Leopold's car that night, while the men claimed to be using it.
