MARQUETTE — A Laurium man charged with storming the U.S. Capitol building on Jan. 6, 2021, made his initial court appearance in federal court Wednesday.

Adam Mancuso appeared in U.S. District Court in Marquette.

The criminal complaint was unsealed Thursday afternoon in the case, which had been filed Aug. 23.

The FBI first received a tip about Mancuso six days after the event, notifying them of Facebook selfies he took inside and outside the Capitol building. They matched the Hatchetman logo hat he wore in the footage, an emblem used by the Michigan rap group Insane Clown Posse, to several other photos on his Facebook page. Watermarks on the photos were also linked to his business Adam’s Stash, where he sells ICP-related jewelry.

Surveillance footage from the Capitol, open-source videos and selfies cited in the complaint put Mancuso at several points in the Capitol building that afternoon. He entered the building through the Senate Wing door at 2:58, moving through the Crypt and Hall of Columns before leaving at 3:04 p.m. In that time, he took selfies, filmed video, and picked up a sign discarded by another protestor before putting it down when confronted by an officer.

He re-entered the Capitol at the Rotunda at 3:20 p.m. as it was being cleared, court documents said. He worked his way to the front of the crowd and began vaping while filming. He put on a gas mask and pushed closer to the front, raising his arms to film. At his closest point, he was chest to chest with an officer, who pushed him away from the line. As officers continued to push the group out, Mancuso was forced toward the exit, leaving the building for the last time at 3:27 p.m.

Agents also conducted surveillance of Mancuso back in Michigan, where they spotted a man matching the Jan. 6 images.

Residents had noticed federal police activity in the Laurium area Wednesday morning. FBI spokesperson Jordan Hill confirmed Thursday FBI members had been in the village conducting “court-authorized law enforcement activity.”

Mancuso was arrested Wednesday and released on bond.

Mancuso faces the four misdemeanor charges given to most Jan. 6 defendants: knowingly entering or remaining in any restricted building or grounds without lawful authority; intent to impede or disrupt the orderly conduct of government business or official functions, disorderly conduct in a Capitol building or grounds; and parading, demonstrating or picketing in a Capitol building.

He is next scheduled to appear via Zoom for a hearing in District of Columbia District Court on Sept. 10.
