Master Security Officer killed at U.S. Census Bureau

A U.S. Census Bureau security officer was shot and killed Thursday by a man whom police said kidnapped a woman in a domestic dispute and led officers on a car chase through Maryland and Washington D.C. before being shot and captured.

A spokeswoman for Prince George's Hospital Center told the Associated Press that the officer, identified as Lawrence Buckner, was pronounced dead at 7:19 p.m. local time. 

D.C. Police Chief Cathy Lanier told a news conference that Buckner was shot after he approached a car that matched a description of the kidnap suspect's vehicle. The shooting caused an hours-long lockdown at the Census Bureau campus in Suitland, Md., just outside Washington. 

The shooting was not terrorism-related, FBI Baltimore spokeswoman Amy J. Thoreson told the Associated Press in an e-mail, a statement that Lanier confirmed.
