The FBI office in Knoxville, Tennessee, wants to make sure images of their most recent serial bank robber are larger than life.

The bureau has partnered with an outdoor advertising agency to put images of the robber on billboards in eight states across the Southeast. The images were drawn from surveillance cameras that include the robber's full facial features since he has conducted the robberies without masks or disguise.

Based on information obtained after the billboards went up, authorities in the Eastern District of Tennessee issued a federal arrest warrant charging 36-year-old Chad E. Schaffner with two counts of bank robbery and two counts of use of a firearm during a bank robbery. He is suspected of robbing nine banks and one credit union throughout Kentucky, North Carolina, South Carolina, and Tennessee. The Bureau did not release which banks or credit union had been robbed.
