An armed assailant stormed past a U.S. Capitol security checkpoint, mortally wounding Officer Chestnut. In the initial crossfire between the gunman and Capitol Police, a gunshot injured a tourist. As congressional aides and Capitol visitors sought cover, the assailant ran toward a door that led to the suites of then-Majority Whip Tom DeLay of Texas. Detective Gibson, a member of DeLay’s security detail, told aides to seek cover. Gibson and the assailant exchanged gunfire. Although fatally wounded, Gibson’s action enabled other officers to subdue the gunman.
