Police resolved a hostage situation at Discovery Communications Inc. headquarters in Silver Spring, Md., at approximately 5 p.m. local time Sept. 1. The situation began at approximately 1 p.m. when a man identified by media as James Jay Lee entered the lobby of the building armed with a handgun and what is believed to have been an improvised explosive device (IED). Lee then allegedly fired one to six shots and took three people hostage, one of whom was rumored to be a security guard. After a four-hour standoff, law enforcement agents heard a pop, which may have been the IED Lee was believed to have had. After hearing the noise, agents shot and killed Lee. Reports thus far indicate no one else was hurt.
