Police killed a man upset with the Discovery Channel network's programming who took two employees and a security guard hostage at the company's headquarters outside of Washington on Wednesday, officials said. All three hostages escaped safely. Police in Silver Spring, Maryland spent several hours negotiating with the gunman, who entered the suburban Washington building early Wednesday afternoon waving a handgun and with canisters strapped to his body. Montgomery County Police Chief Thomas Manger said one explosive device detonated on the gunman's body when they shot him, and authorities were working to determine whether two boxes and two backpacks he also had with him were explosives. The 1,900 people who work in the building were able to escape to safety. Manger said officers were monitoring James Lee on building security cameras, and officers moved in when they saw him point the handgun at one of the hostages. Lee previously protested outside the building, where he was arrested and charged with disorderly conduct in early 2008, according to court records.
