A former Green Beret and one-time congressional candidate arrested last month for his alleged participation in the Capitol riot was illegally stockpiling explosives prior to being jailed on charges related to the Jan. 6 pro-Trump siege, according to an FBI search warrant filed Friday in Washington, D.C. federal court. When federal agents searched 47-year-old Jeremy Brown’s Florida home in October, they reported finding a short-barrel rifle, a sawed-off shotgun, more than 8,000 rounds of ammunition, and two hand grenades. But it was a picture included in a sales listing for his house on Zillow that led to his latest troubles. In a photo from “what appears to be Brown’s office,” FBI agents spotted a whiteboard with columns labeled “Food,” “Clothing,” “Shelter,” “Currency,” “Communicate,” “Move,” and “Shoot,” the warrant states. In the “shoot” column, it continues, “there are numerous firearms listed and explosive devices such as ‘flash bangs.’” The entry on the whiteboard indicated that Brown had the flash bangs “on hand,” the filing says, adding that Brown “is not registered to possess explosive devices.”

Agents are now seeking to search a trailer located on Brown’s property, which the FBI believes he bought about a month ago: “[I]t is unlikely that an individual would market a home available for public inspection with guns and explosives inside of the home, [thus] it is probable ammunition, and explosives, which constitute potential evidence in the investigation, have been moved to the RV or trailer,” the warrant states. Brown remains jailed after a judge in October ruled he was a danger to the community.
