|Discovery Building suspect James Lee: Montgomery County Police|
SILVER SPRING, Md. — Police shot and killed a gunman who held three hostages for several hours Wednesday at the Discovery Communications building in Silver Spring, Md., authorities said. They said the hostages were safe.
At least one explosive device went off when he was shot, and other explosive devices could still be in the building in Montgomery County in suburban Washington, D.C., they said. It was not clear whether there was any damage.
Montgomery County police Chief Thomas Manger said no one was believed to have been injured beyond the gunman. The building in the close-in suburb of Washington was safely evacuated, including the Discovery Kids Place day care center, police said.
Law enforcement authorities told NBC News they believed the man was James Jay Lee or James Jae Lee, 43, a longtime protester at the building who was sentenced to six months of supervised probation for disorderly conduct in March 2008.
