The alarming incident near the Washington Monument and the National Mall began after a plainclothes Secret Service agent allegedly spotted Michael Marx attempting to conceal a firearm on the right side of his body while near 15th Street and Madison Drive, according to court documents.
The agent reportedly alerted additional Secret Service personnel, who later encountered Marx near 15th Street Southwest and Independence Avenue Southwest as he was allegedly “walking along the path of” Vance’s motorcade, which had departed the White House moments earlier, the complaint states.
According to investigators, agents exited their vehicles and began shouting commands at Marx, who allegedly ran across the street alongside a group of bystanders while pulling a handgun from his waistband.
Once on the opposite side of the street, Marx allegedly turned and fired at a Secret Service agent, with one of the shots striking a child in the leg while the juvenile was with family members nearby, according to court documents.
Agents then allegedly returned fire, striking Marx in the hand, left arm, and upper abdomen, the complaint states.
