Tim Blixseth, the former billionaire and founder of the luxurious Yellowstone Club ski and golf resort in Montana, was sent back to jail Oct. 19 after a U.S. district judge said that he was unsatisfied that Blixseth hadn't come clean on the $13.8 million that he received from the sale of a Mexican resort, the Associated Press reported yesterday. Blixseth was tossed into a Great Falls, Mont., jail in April after a judge found the developer in contempt for failing to account for the millions he owes creditors. Prosecutors said that Blixseth owes more than $250 million to his lenders. Blixseth sat silently in court on Monday as his accountant took nearly six hours to explain Blixseth's sale of a Mexican resort, with funds funneling through more than 20 different businesses and/or bank accounts. The accountant insisted that all of the $13.8 million has been spent. U.S. District Judge Sam Haddon ordered Blixseth back to jail until at least Nov. 20, when he's expected to rule on whether Blixseth had provided sufficient detail on the Mexican funds.
