The couple moved to Indiana in 1999 and began a ministry targeting Mormons in the Midwest. Stationed at the Great Lakes Naval Training Center in Chicago's North Shore, the couple preached at Christian churches across the Midwest about Mormonism. On a visit to Nauvoo in 2002, Mormons barred Hulse from attending a temple open house because they deemed him disruptive.

The couple moved to Nauvoo in late 2005 to take over the Christian center. The storefront is filled with boards, pamphlets and literature such as "the troubling story of a self-proclaimed prophet" Smith.

Last fall, as their Christian television ministry "Truth Proclaimed" spread internationally, the Hulses say threats came. The couple now fear the threatening e-mail received before Christmas is being ignored by Utah investigators who they say want to protect Mormons.

Authorities traced the e-mail to an address belonging to a Mormon, Phil Rogers, of Farmington, Utah, a few miles north of Salt Lake City.

In a telephone interview with the Chicago Tribune, Rogers repeated what he told investigators: Someone hacked into his Internet account while he was using an open router. Internet security experts contacted by the Chicago Tribune said if Rogers allowed access to his router, tampering could be easily done by anyone in his neighborhood.

Bill McGuire, the Utah assistant county attorney investigating the case, said he is awaiting further police reports to determine if criminal charges will be filed and against whom.

"We prosecute Mormons all this time," said McGuire, a Mormon, who chuckled at the Hulses' accusation of a cover-up.

Still, Rocky Hulse doesn't trust the Mormons.

"Look at their history full of lies and deceit," he said. "We are a voice of truth, and they will do anything to silence it."
