A police officer is interrogating a suspect in a white collar crime case where several hundred thousand dollars are suspected to have been stolen. When asked if knows anything about the missing money, the suspect puts his hands over his mouth and says, "I don't know what you're talking about." What conclusion can the investigator draw from the suspect's behavior and answer?

The conclusion that can be drawn is that the suspect is probably lying.

Explanation:

There are several signs that a person may be lying, many of them conveyed through body language. Among the most "famous" ones are covering one's mouth, touching one's nose, scratching one's neck, avoiding eye contact - or the opposite, maintaining prolonged eye contact without much blinking. The habit of covering one's mouth when lying usually appears during childhood. It's as if the person's trying to hold the words back. While doing so, they can use just a few fingers, or even the whole hand.
