Time is always of the essence for the FBI, but it is now more than ever.
Agents need to find a serial bank robber in the western suburbs before the end of the year, according to the Chicago Tribune.
The robber, called the "Wheaton Bandit," held up 16 banks and credit unions between January 2002 and December 2006. Seven of the banks were in Wheaton.
Now, the organization is asking for your help. The statute of limitations on bank robberies is five years, and the expiration date for these cases is Dec. 7.
The suspect is described as a man between 25 and 30 years old, with a medium build and blue eyes. He is between 5 feet 10 inches and 6 feet 2 inches tall. He used a hood or ski mask and carried a semi-automatic handgun during each robbery.
He is also thought to have prior law enforcement or military training due to the way he handles the weapon.
