Monona County authorities have identified and charged a man following a high-speed chase and bank robbery Tuesday in western Iowa. 24-year-old Bradley Marr of South Sioux City, Nebraska has been charged with first-degree theft, second-degree robbery and two counts of theft. Marr allegedly walked into the Moorhead State Bank in Moorhead about 1 P.M., displayed a handgun, was given an undisclosed amount of money, then fled on a motorcycle. He then led officers on a chase on Interstate-29 at speeds exceeding a hundred miles an hour. The chase ended when a tire on the motorcycle blew and he crashed in Pottawattamie County. He’s being held in the Douglas County Jail in Omaha while he awaits extradition to Iowa.
