The United States Holocause Memorial Museum shooting was a shooting at the national Holocaust Museum in Washington, D.C. on June 10, 2009.  At about 12:49pm, 88 year-old James von Brunn drove his car to the 14th Street entrance of the museum. Von Brunn entered the museum when security guard Stephen Tyrone Johns opened the door for him. Authorities said he pulled out a 22-caliber rifle and shot Johns who later died of his injuries. Two security guards, Harry Weeks and Jason "Mac" McCuiston, returned fire, wounding von Brunn. The entire incident took less than 35 seconds.
