As the three hostages at Discovery Channel's headquarters appeared ready to make a run for it, police said Thursday that a SWAT team officer quickly shot and killed the increasingly agitated gunman who had explosives strapped to himself, ending the four-hour standoff.

Authorities saw the hostages begin to move on building security cameras and heard a "pop" they believed to be a gunshot or an explosive device, Montgomery County Police Chief Thomas Manger said. That's when an officer shot the gunman, James J. Lee, in the lobby of the building in Silver Spring, just outside the nation's capital. None of the hostages were hurt.

Lee had said he hated the company's shows such as "Kate Plus 8," claiming they promoted population growth. Lee said the environmental programming did little to save the planet. About The Author: Steven Rogers
