One of the security guards injured earlier today when a gunman opened fire at the Holocaust museum in Washington, D.C. has died from his wounds. He had been rushed to the hospital for treatment. The gunman remains in critical condition in hospital after being wounded by return of fire.

American television networks are naming 88 year old James Von Brunn as the gunman. Von Brunn has known links to white hate groups and anti-government organizations. Police and investigation officials have not yet confirmed his identity.
