A husband murders his wife in the car, and, careful not to leave any fingerprints, throws her out of the onto the side of the road. He then goes to a cliff and throws the knife he used off of it. He drives back home and pretends nothing happened. Later that day he gets a phone call from the police. "Sir, your wife has been found dead. Please come quick" the police said. He immediately drove to where his wife lay dead and was arrested by the police. How did they know it was him?
