Madison Police say the arrest of two suspects may clear a string of nine bank robberies committed in the area over a six-week period.  Twenty-nine-year-old Jonathon Thompson and 18-year-old Kiefah Marbra were arrested last week.  Investigators think they can be connected to bank robberies in Madison, Fitchburg, Sun Prairie and Middleton.  Those two may not have committed all of the robberies, but police think they are connected to the crew who did the crimes.
