US / Pentagon shooting Pentagon, Marine Museum Shootings Linked Same gun was used in both cases, ballistics reveals By Kevin Spak, Newser Staff Posted Oct 27, 2010 9:55 AM CDT Copied A law enforcement officers searches for evidence along the I-395 expressway adjacent to the Pentagon following the shooting, Oct. 19, 2010.

Officials suspect a third shooting at a Marine Corps recruiting office this week may be related as well. “I don't think at this point in time we are prepared to say this is a serial of any kind,” a spokesman told the Washington Post. “But the targets are all blatantly military.” Both the Pentagon and the museum are within range of a busy interstate. The buildings are roughly 30 miles apart. Both shootings occurred either late at night or early in the morning, when the buildings were either unoccupied or close to it. For that reason, police say they view the shootings mostly as vandalism. “But it is a cause for concern that someone would be doing this.” (More Pentagon shooting stories.) Report an error
