BRISTOL, Pa. (CBS) — Hiding “in plain sight,” that is how the Bucks County district attorney describes the four residents who were emboldened to travel and post on social media about their role in January’s Capitol riots in Washington, D.C.

Today, we learned a Bristol woman was arrested for her role in the violence.

Police were tipped off to 37-year-old Raechel Genco after her boyfriend was arrested for his role in the violence in D.C. The pair reportedly lived together in Bristol, in a county you may not expect to be at the top of the most-wanted list.

“To learn that people in Bucks County stand accused of that, it’s disappointing,” Bucks County District Attorney Matt Weintraub said.

This week, the criminal complaint against Genco, of Bristol, was unsealed, making her the fourth Bucks County resident charged in the Jan. 6 Capitol riots.

Photos show Genco in Washington with her boyfriend, Ryan Samsel, who was arrested last month for reportedly knocking down barricades that injured an officer. During the arrest, police realized the couple allegedly traveled together in Genco’s Dodge Charger.

“We were able to learn of the connection between the two of them,” Weintraub said.

Also in January, Doylestown residents Dawn Bancroft and Diana Santos-Smith were charged for entering the Capitol. Bancroft posted on social media she wanted to shoot House Speaker Nancy Pelosi.

“They’re not even hiding in plain sight, they are in plain sight,” Weintraub said.

It’s the seemingly normal citizens who now face federal charges that are especially concerning to the team researching extremism at George Washington University.

“We don’t have a typical profile of a domestic violence extremist,” Bennett Clinton said.

Bucks County now leads the nation — tied with Los Angeles County, California, and Franklin County, Ohio — for the most resident arrests so far.

“I think a lot of folks have sort of a stereotypical image in their head of what one of these individuals who participated in the Capitol siege look like, and I don’t think the data supports any of those stereotypical images,” Clinton said.

We tried to reach out to Genco, but we could not reach her for a comment.

And on the possibility of more arrests to come, “I can only say the investigation is not over,” Weintraub said.

EDITOR’S NOTE: Last night, Eyewitness News reported on a Bucks County woman who was arrested on charges arising out the January 6th riot at the Capitol. At the conclusion of the report and on our website, we stated that Jim Worthington, a Bucks County businessman, was interviewed by the FBI and stated that “so far, he is not facing any charges.” In making this statement, we were wrong. Mr. Worthington had nothing whatsoever to do with the events we reported on. Shortly after January 6th, Mr. Worthington publicly denounced any and all violence at the Capitol. We apologize to Mr. Worthington.
