FBI Investigates - The Crime

A security guard making his hourly rounds at the Smith Federal Building in Washington, D.C., noticed light coming from the building's back door. He looked inside and saw a wooden box with a note taped to the outside: "do not come any Closer. This box WILL EXPLODE." Near the box, the guard noticed a large black flashlight. Realizing the potential danger of the situation, he carefully retraced his steps and called for assistance.
