A Marine stationed at Camp Lejeune is accused of entering the U.S. Capitol building during the Jan. 6 attack. Federal agents arrested Sgt. Dodge Dale Hellonen in Jacksonville, North Carolina, on Wednesday.

The FBI said Hellonen went into the Capitol during the attack with two other active-duty Marines. A mob supporting former President Donald Trump stormed the Capitol on Jan. 6, 2021, as Congress met to certify the election of President Joe Biden.

The investigation into Jan. 6 has become the biggest in FBI history. More than 950 people have been arrested for their roles in the attack. More than 20 people from North Carolina have been charged, including one soldier from Fort Bragg who joined the U.S. Army after Jan. 6.

Hellonen faces four charges, including disorderly or disruptive conduct in a restricted building or grounds and parading, demonstrating or picketing in a Capitol building. He is not accused of assaulting police or any violent offenses that others have been charged with.

Hellonen, who has been in the Marines since 2017, is charged in the same case with Cpl. Micah Coomer and Sgt. Joshua Abate.

The FBI affidavit states Coomer was stationed at Marine Corps Base Quantico, near Washington, D.C., at the time. He is now at Camp Pendleton in California, the Marine Corps said. Abate is based at Fort Meade in Maryland, according to the Marine Corps. Both Abate and Coomer enlisted in 2018.

"We are aware of an investigation and the allegations. The Marine Corps is fully cooperating with the appropriate authorities in support of the investigation," a Marine Corps spokesperson said in a statement.

The FBI said Coomer posted photos online of himself, Hellonen and Abate as they walked around the Capitol building. The FBI got a search warrant for Coomer's Facebook and Instagram accounts after seeing his photos from inside the Capitol.

The trio are seen in the photos and surveillance video walking through the Capitol Rotunda, Hellonen carrying a yellow "Don't tread on me" flag, according to the FBI.

Surveillance video shows the men putting a red "MAGA" hat on a statue and taking pictures with it, according to the FBI.

"The group remains inside the Rotunda for approximately 30 minutes until police arrive and form a line to direct people out of the Building," the affidavit states.
