Shawna Cox, a key figure in the Oregon militia standoff who is accused of conspiring against the government, says she “suffered damages from the works of the devil” and wants federal officials to award her $666bn.

Cox, a 59-year-old Kanab, Utah woman facing federal charges for her role in the armed occupation of a wildlife refuge, has filed a “counter criminal complaint” against “federal employees” seeking “six hundred sixty six billion, six hundred sixty six million, six hundred sixty six thousand, six hundred sixty six dollars and sixty six cents”.

Cox is one of two women in the group of 25 people that federal authorities have charged in connection with the occupation of the Malheur national wildlife refuge that began 2 January and ended last week after a dramatic standoff with the FBI.

The Utah anti-government activist, who officials say was an important leader and spokeswoman for the Oregon militia, is also one of the few defendants who was permitted to return home on house arrest as the case moves forward. Most of the arrested rightwing protesters, including occupation leader Ammon Bundy, remain in jail.

Cox has apparently used her free time to write up an eight-page countersuit that includes rants about government corruption and abuse, naming many of the central federal and local Harney County officials involved in the arrest and prosecution of the protesters.

“I came to the assistance of economically vulnerable individuals who were being harassed, threatened, intimidated, persecuted and incarcerated by arrogant, narcissi Federal Government officials who have organized together to highjack and steal our Constitutional form of government from the people of the United States of America (sic),” she wrote in the complaint filed Wednesday.

She also discusses ranchers Dwight and Steven Hammond, the Oregon father and son whose imprisonment inspired the standoff. And wrote at length about the death of LaVoy Finicum, the occupation spokesman who Oregon state police officers shot and killed when they attempted to arrest him outside of the refuge occupation last month.

Cox was in the car with Finicum before he was killed, and she was arrested soon after. “State and Federal employees organized together to attempt to murder me and they executed … Lavoy Finicum … to terrorize the people of the United States of America so they could continue to socialize and communize the United States of America, and continue to use their State and Federal Bar licenses to steal the lives, liberties and properties of economically vulnerable individuals,” Cox wrote.

The occupation of the federal buildings was a “legal way” to challenge the government, she further argued. Cox also listed dozens of criminal offenses that she alleges were committed against her and the other protesters, adding up to damages “in excess of $666,666,666,666.66”.

Cox did not immediately respond to requests for comment Thursday morning. A spokesperson for the US attorney’s office in Oregon also did not respond to a request for comment.
