After the holdup at the beginning of the story, Mr. and Mrs. Tulley flee to their home. The outside of their house has windows on both sides of the front door; however, there are no windows on either side of the front door inside the house. Artwork hangs from where the windows should be. This is clearly evident when Mrs. Tulley must crack open the front door in order to look outside because there are no inside-windows.
When the robbers arrive home, their car will not allow the garage door to close, and the edge of the door is a couple of feet from the ground. After the husband leaves the house, the garage door is nearly closed- only inches away from the ground.
After getting the drop on Matthews and Williams, the robber tells his wife to pull the ignition wires and disable the radio in the police car. He overlooked the fact the salvage yard had a telephone.
