 Malkus said that he went to the spot, but found no trace of the girl. Police detectives continued the search for the girl, but what few clues they had led nowhere. They searched for the young man that Bonnie was allegedly out with that night, trying to trace the names that were in a small white address book found in Bonnie's room. They questioned 38 young men. Two of them were later given lie detector tests, but the trail soon petered out and went cold.
