Detectives scour the Chamber looking for spent bullets and other evidence after four Puerto Rican nationalists opened fire from the gallery onto the House Floor on March 1, 1954. Armed with handguns, the dissidents—advocating for independence for their homeland—wounded five Members: Alvin Bentley, Ben Jensen, Clifford Davis, George Fallon, and Kenneth Roberts. All five survived the attack, although Bentley was critically wounded.
