The Sheriff says Kimble was tried, convicted, and sentenced to death for strangling his wife, but Kimble's wife was bludgeoned to death with a lamp, not strangled.
When Kimble enters the diner he asks for coffee and a bowl of chili. He gets a glass of water and the chili but no coffee. After he runs out of the diner the sheriff comes in and soon collects his plates for fingerprints. A cup of coffee is next to the chili.
