He's back in a nearby minimum-security camp with full privileges after spending 20 days in the dock. One of his lawyers, Pat Shea, tells The Associated Press that DeChristopher was placed in confinement for an ill-advised word he used in an email to supporters. He used the word "threaten" about returning a donation that was made to his legal defense fund.
