The FBI now believes he has robbed 11 banks in Colorado and one in Arizona. They say he seems to prefer banks inside grocery stores.

Investigators think there is a second person waiting in a get-away car outside the banks, but at this time they do not have a description of that person.

He is described as a man in his late 20s or early 30s, he has a slim build, is between 5 feet 5 inches to 5 feet 10 inches tall and has blondish hair. He may have facial hair and acne or pock marks on his face. He usually wears a hat and carries a backpack.
