The FBI announced plans Tuesday to post a picture of him on billboards in hopes of catching him.
The man is believed to be 50 to 60 years old. The FBI describes him as about 6 feet tall, bald and heavy. He is wanted in 12 states: Alabama, Arkansas, Georgia, Kansas, Florida, New York, Oklahoma, Texas, Mississippi, Missouri, Tennessee and Virginia.
Though the man has been dubbed the "Granddad Bandit,'' not much is known about him. The FBI says it typically assigns a name to serial bank robbers to give the public a reference point.
