Creditors say a former billionaire should remain in the Montana jail where he has been held for almost two months for not disclosing what happened to $13.8 million from a property sale in Mexico.

The creditors' attorneys on Friday described as a "repackaged mishmash" more than 9,000 pages of financial documents submitted by Tim Blixseth as he seeks to be freed from the Cascade County jail.

Blixeth founded Montana's ultra-exclusive Yellowstone Club. U.S. District Judge Sam Haddon jailed him for contempt April 20 after growing impatient with his incomplete accounting of the Mexico property sale.

Creditors from the Yellowstone Club's 2008 bankruptcy say Blixseth owes $286 million that he drained from the resort for personal use. They accuse Blixseth of hiding the money. He has claimed he spent it.
