One of two Western Pennsylvania men arrested on charges stemming from the Jan. 6 violence at the U.S. Capitol is being held in the Butler County Prison.

Jorden R. Mink of Oakdale, Allegheny County, was placed in the prison Tuesday after his arrest by FBI agents. He is awaiting a preliminary examination and detention hearing that will be scheduled Jan. 27 or 29.

The U.S. Attorney's Office accused Mink of wielding a baseball bat “to shatter a window at the Capitol,” according to court documents.

It was not immediately known why the defendant was placed in the county prison following his arrest. Warden Joe DeMore said Wednesday that he does not comment on the housing status of federal inmates.

But the prison has been housing more federal prisoners.

“The federal agencies are using the Butler County Prison as a hub for new (federal) detainees,” said Sheriff Mike Slupe, who also is a member of the prison board.

There are 167 federal inmates at the prison, he noted, with possibly 60 more to come.

Margaret Philbin, spokeswoman for the U.S. Attorney's Office in Pittsburgh, said Wednesday that she had no information about if or where Mink was being detained. The U.S. Attorney's Office also does not comment on the status of detainees due to security reasons.

Matthew Perna of Sharon, Mercer County, also was arrested in connection with the Capitol violence. He is free on $10,000 unsecured bail while awaiting his next court appearance.

Scott Brady, U.S. Attorney's Office for the Western District of Pennsylvania, said his office is working closely with the FBI and the U.S. Attorney's Office for the District of Columbia to identify residents of Western Pennsylvania who violated federal law at the Capitol.

“The charges announced (Tuesday) against Jorden Mink and Matthew Perna are the result of this collaboration,” Brady said in a statement. “Together with our federal, state and local partners, we will ensure that our community is safe from those who would incite or commit further violent acts. Such criminal activity will be met with swift justice.”

Mink is charged with unlawful entry on restricted building or grounds while using or carrying a deadly or dangerous weapon; unlawful injury to property on Capitol grounds; violent entry, disorderly conduct, physical violence on Capitol grounds; destruction of government property valued at more than $1,000; theft of government property; and aiding and abetting.

Perna is charged with knowingly entering or remaining in any restricted building or grounds without lawful authority and disorderly conduct on Capitol grounds.

The U.S. Attorney's Office in the District of Columbia is prosecuting Mink, Perna and more than 100 other accused rioters.

The violence broke out, according to an Associated Press report, when far-right Trump supporters, galvanized by his claims that the election had been stolen from him, overran the police and bashed their way into the building while Congress was certifying the Electoral College vote.

The attack left a Capitol police officer and four others dead. More than 125 people have been arrested over the violence.

According to the criminal complaint against Mink, the FBI received a tip Jan. 15 that he was depicted in images that showed his “unlawful, violent entry” into the Capitol building and the destruction and theft of property on the outside and inside of the building.

Following the tip, FBI agents said they compared photos of Mink to videos of the violence that were posted on social media, specifically of a man using a bat to smash a window.

“Close scrutiny of Mink's tattoos on his neck and fingers are also consistent with images of the individual wielding the baseball bat at the Capitol,” an FBI affidavit said.

“The same individual matching Mink's description enters the Capitol building through the broken window and removes property from the interior of the Capitol, to include chairs, delivering it into the hands of people in the crowd on the exterior of the building.”

A review of Mink's social media, including an Instagram account entitled,“tattedup_badison,” authorities said, includes a “selfie” of him Jan. 3 at the Lincoln Memorial.

An earlier post from Nov. 3 shows a selfie of Mink holding a firearm with a sticker that says, “I Voted.”

The caption to the post reads, “The ballot is stronger than the bullet — Abraham Lincoln.

“Well … my magazines will be fully loaded just in case it's not,” the affidavit said.

Mink's attorney, Michael Moser of Allison Park, declined comment Wednesday.

Agents met with Perna on or about Jan. 14 at his home, authorities said.

“Perna said that he had attended President Trump's rally (Jan. 6), and that he marched with others to U.S. Capitol after the rally,” according to documents.

He recounted that he and a friend went to the top of the steps of the Capitol building's west side, and he was surprised that the door was open.

Perna claimed that he was pushed into the building by a crowd that had gathered behind him, documents said. Perna claimed that it was not his intention to enter the Capitol.

Perna's attorney was not immediately known, and he could not be reached for comment.
