Man Found Dead Next to a 13 Story Building
A man was found dead next to a 13 story building. The police say it was a suicide, but you say it was a homicide (someone killed him).
To prove this, you go to each floor on the building, open the window, and toss a penny out. You do this to each floor until you reach the 13th floor, open the window, and toss a penny out.
