The bandit was described as a white man between the ages of 25 and 35. He is approximately 6 feet tall, slender and weighs between 150 and 170 pounds.
FBI spokesman Dave Jolly said witnesses told the Rocky Mountain Safe Streets Task Force that the suspect resembled one of the male co-stars of the 1970's sitcom, "The Brady Bunch." Investigators believe he wore a variety of wigs during the crimes.
Jolly said the robber's behavior fits a pattern. He enters the bank, presents a demand note and runs away.
