LAS VEGAS — The top law enforcement authorities from Utah, Arizona, Nevada and Texas gathered in a closed-door summit here, mapping out a cooperative plan to go after crimes within polygamous sects.

Just blocks from the glitzy Las Vegas Strip, federal, state and local authorities met all day Wednesday at the U.S. Attorney's Office for Nevada. Those who attended told the Deseret News they exchanged information and pledged to work together. They mostly discussed the Fundamentalist LDS Church.

"We met a lot of people, exchanged a lot of cards, got a lot of contacts," said Utah Attorney General Mark Shurtleff. "I think it'll facilitate communications in the future."

Asked if the FLDS Church should be concerned about the four states joining forces to investigate any crimes within the group, Arizona Attorney General Terry Goddard smiled.

"You could draw that conclusion," he said.

This was not the joint federal-state task force that the Utah and Arizona attorneys general have sought. The meeting did come out of their very public spat with U.S. Sen. Harry Reid, D-Nev., who accused the two states of "doing nothing" about polygamy.

"We're just here to talk with one another about the issues we have in common," said Nevada Attorney General Catherine Cortez Masto.

The idea of a task force has been met with resistance from federal authorities. On Wednesday, FBI Director Robert Mueller said the agency would assist local law enforcement, but it has other priorities. U.S. Attorney for Utah Brett Tolman said he still did not believe a task force is necessary.

"This is an example of what is necessary," he told the Deseret News as he left the meeting. "Maintaining open, clear communication. There are agencies that are doing a lot, and those agencies need to talk to one another."

Washington County Sheriff Kirk Smith said the meeting was more for coordination, as the states work closer together on any criminal activity within polygamy.

"To meet counterparts from different states and share information and make contacts, I thought it was productive and valuable," added Washington County Attorney Brock Belnap.

Shurtleff said he would like to expand the working group to include Colorado, Idaho and other states where the FLDS Church has enclaves.

"I think everybody has concerns from what they're hearing and what they're seeing," Cortez Masto said. "I think for purposes of our state, we want to make sure we're vigilant and we're being proactive."
