WASHINGTON - An 88-year-old gunman with a virulently anti-Semitic past fatally shot a security guard inside the crowded U.S. Holocaust Memorial Museum on Wednesday before being shot himself by other officers, authorities said.
The assailant was hospitalized in critical condition, leaving behind a sprawling investigation by federal and local law enforcement and expressions of shock from the Israeli government and a prominent Muslim organization.
Washington Police Chief Cathy Lanier said the gunman was "engaged by security guards immediately after entering the door" with a rifle. "The second he stepped into the building he began firing."
Law enforcement officials said James W. von Brunn, a white supremacist, was under investigation in the shooting and that his car was found near the museum and tested for explosives. The weapon was a .22-caliber rifle, they added. They spoke on condition of anonymity, saying they were not authorized to discuss the investigation just beginning.
