A Man Was Found Dead Next To A 13 Story Building

Riddle: 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 of the building, open the window, and toss a penny out. You do this on each floor until you reach the 13th floor, open the window, and toss a penny out. How does this prove it wasn't a suicide?

Answer: If the man committed suicide, he would've left the window open and you wouldn't have had to open it.
