When I lived in Bismarck 15 years ago, my landlady worked for the Federal Bureau of Prisons. Her job was to help keep tabs on the federal prisoners being held in the North Dakota State Penitentiary. At least back then, many federal prisoners were housed in state pens. Often times, it was to place them in locations where their identity (and deeds) wasn't known to other prisoners or to take make use of special facilities or services in a particular state. If this is still the case and Rodriguez isn't sentenced to death, I imagine it's possible that he could end up in a state pen far from North Dakota.
