 Malquist was brought back to the station on Monday morning. He told the same story over again, and detectives were now convinced that he had memorized it. Chicago detectives offered to send for a polygraph machine, and it arrived at the station later that day. Malquist was given the first of two lie detector tests. He failed miserably the first time, and so detectives agreed to a second examination at the offices of John Reed, a polygraph expert and police consultant.
