If he is convicted on the kidnapping charge he faces, a 42-year-old Madison man could spend the rest of his life in prison. Marvin Baker is accused of getting into a 22-year-old woman’s car last April while she was stopped at a stop sign at the start of a crime spree. Prosecutors say he carjacked three women before driving the third car to Indiana. In each instance, he held the women against their will. Baker made an appearance in Madison federal court Thursday.
