WATCH: QAnon-loving Capitol rioter thought JFK Jr would be 'sworn in' as Trump's vice president on Jan 6

An Idaho woman who participated in the storming of the Capitol on Jan. 6 has been arrested and was "taken into custody without incident" by officers with Homeland Security Investigations, the Boise Police Department, and members of the FBI's Joint Terrorism Task Force, KTVB reports.

Yvonne St Cyr, 53, has been charged with "Knowingly Entering or Remaining in any Restricted Building or Grounds Without Lawful Authority and Violent Entry and Disorderly Conduct on Capitol Grounds" -- both misdemeanors.

In a video posted to Facebook five days before the Capitol attack, St Cyr says that she heard that then-Vice President Mike Pence had resigned -- a claim that is blatantly false.

"If Pence resigned, what if JFK Jr. is gonna be sworn in as the vice president on [Jan. 6], and I will be there to see it and you can all pound sand because I am telling you, he is alive," she said, referring to former President John F. Kennedy's son, who died in a plane crash in 1999.

St Cyr faces up to a year and six months in prison.

"In the live-streamed video, St Cyr filmed the destruction of an office window from within the Capitol and continued to record herself standing in the window and shouting at the crowd located on the west side of the Capitol grounds," FBI Special Agent Matthew Gano wrote in a criminal complaint.

In a live video that appears to have been recorded following the riot at the Capitol, St Cyr talks about breaching the Capitol building and her belief in the QAnon conspiracy theory.

"That election was stolen, 100%, without a doubt. There's tons of evidence," she says in the video. "That's why we stormed the Capitol, because we didn't lose, they stole this election. And if we don't fight then we lose everything."
