truthful than verbal language involved the rape of a young woman on the
Parker Indian Reservation in Arizona. A suspect in the case was brought
in for questioning. His words sounded convincing and his story was plau-
sible. He claimed he hadn’t seen the victim and while out in a field had
gone down a row of cotton, turned left, and then walked straight to his
house. While my colleagues jotted down notes about what they were
hearing, I kept my eyes on the suspect and saw that as he told the story
about turning left and going home, his hand gestured to his right, which
was exactly the direction that led to the rape scene. If I hadn’t been
watching him, I wouldn’t have caught the discrepancy between his verbal
(“I went left”) and nonverbal (hand gesturing to the right) behavior. But
once I saw it I suspected he was lying. I waited a while and then con-
fronted him again, and in the end he confessed to the crime.
