I don't know about the solitary confinement but if he actually did this "Nordean, dressed in all black and wearing a tactical vest, instructed his fellow members on how to use encrypted communications and the military-style equipment they had acquired. He then issued specific orders: “split up into groups, attempt to break into the Capitol building from as many different points as possible, and prevent the Joint Session of Congress from Certifying the Electoral College results,” prosecutors said." Then they did it. No one told them to break in.
