Gunshots at U.S. Holocaust Museum

So sad. MSNBC:

An elderly gunman exchanged fire with security guards inside the U.S. Holocaust Memorial Museum on Wednesday. One security guard and the gunman were taken to a hospital with life-threatening injuries.

Law enforcement officials identified the suspect as James Wenneker von Brunn, 88, from the Eastern Shore of Maryland, NBC News reported. NBC said he may have had connections to hate groups or anti-government groups.

D.C. police spokeswoman Traci Hughes said the suspect walked into the museum at about 12:50 p.m. ET with a rifle and shot a guard. U.S. Park Police Sgt. David Schlosser says one or more guards at the museum returned fire, hitting the suspect.
