Police say they're treating this morning's shooting at the Pentagon as a "random event." No one was injured in the pre-dawn incident in which shots were fired into two windows, apparently with a high-powered rifle. A Pentagon official said officers reported hearing five to seven shots about 4:55am near the south parking lot of the Pentagon. The building and the roads leading to it were briefly shut down.
"Right now we consider this a random event," he said. But he added that authorities were looking at whether the shooting was related to Monday's discovery of bullet holes in windows at the National Museum of the Marine Corps in Triangle, Va., about 30 miles south. An internal search of the Pentagon found fragments of two bullets still embedded in two windows—one on the third floor and one on the fourth. The bullets had shattered but did not penetrate the windows. Those offices were unoccupied at the time. (Read more Pentagon stories.)
