"What we're asking there is that we get that information after they finish the criminal work, but before they give it back to the FLDS," he told the Deseret News.

The UEP was taken over by the courts in 2005, amid allegations that Jeffs and other top FLDS leaders had mismanaged it. The trust controls homes, businesses and property in the FLDS strongholds of Hildale, Utah; Colorado City, Ariz.; and Bountiful, British Columbia, in Canada.

The courts ordered reforms recently, paving the way for private property ownership.

Wisan said the information that was taken from the YFZ Ranch is valuable to him — records dealing with property and UEP assets have disappeared, been destroyed or moved. Already, he has managed to get access to documents and evidence seized from a Cadillac Escalade when Jeffs was arrested outside Las Vegas in 2006.

"We have sprinkles on the frosting, but we don't have the cake or the frosting," Wisan said.
