A Montana man accused of disturbing a sacred Burns Paiute archeological site by using heavy equipment to dig a giant latrine for protesters became the 26th person charged publicly in the occupation of the Malheur National Wildlife Refuge.

A judge on Monday unsealed the name of Jake Ryan that had been concealed in an indictment filed March 8 in U.S. District Court in Oregon.

Ryan and fellow occupier Travis Cox are the only two of the 26 defendants who haven't been arrested, said Assistant U.S. Attorney Craig Gabriel.

Prosecutors in Portland wrote in court papers that it was no longer necessary to hide Ryan's identity because his family knows about the indictment and his family has hired an attorney for him.

The federal indictment charges Ryan and one other person -- Sean Anderson -- with "depredation of government property" for allegedly digging two trenches or latrines next to a makeshift camping area at the refuge and causing more than $1,000 worth of damage.

An FBI Evidence Response Team began scouring the scene after the occupation ended Feb. 11, and agents found "significant amounts" of human feces in at least one of two large trenches, prosecutors previously said. Investigators also found an "improvised road on or adjacent to grounds containing sensitive artifacts," prosecutors said.

Ryan faces a second criminal count of allegedly conspiring with the 25 other defendants to prevent employees of the U.S. Fish & Wildlife Service and U.S. Bureau of Land Management from using the refuge from Jan. 2 to Feb. 11. He also faces a third count of allegedly possessing guns or other dangerous weapons or causing guns or other dangerous weapons to be present at the federal refuge in Harney County.

During the occupation, tribal leaders expressed repeated concerns that petroglyphs or historical items sacred to the tribe would be unearthed and destroyed. They asked federal authorities to prosecute any related crimes.

Sheriff Tom Rummel in Sanders County, Mont., said on his office's Facebook page that the FBI notified him last week that an arrest warrant had been issued for Ryan.

Rummell said he's been working with federal officials and Ryan's family to ensure a "peaceful resolution." But he wrote that he has no evidence leading him to believe that Ryan is in Sanders County.

"From the start of this, it has been my intention to make sure that Jake Ryan's safety and rights are provided for, and I will continue to do just that," Rummel wrote. "With that said, I want you to know that Federal Officers have not operated in this county without my knowledge."

The Bundy Ranch Facebook page for supporters of the occupiers states that the "FBI has come to the Ryan family in Plains Montana and told them them their 25 year old son Jake is under must go to jail for being at the refuge. No crime, just terror on a respected God fearing family."

The Facebook page urges people to call the sheriff to encourage him to "stand up" to the FBI.

The sheriff has asked the public in his post to stop calling or emailing him. He's received more than 400 emails and 100 phone calls as of Monday afternoon, he said.
