WASHINGTON (AP) — Authorities say a man kidnapped a woman, fatally shot a Census Bureau guard and led police on a car chase through Maryland and Washington, before authorities cornered him Thursday evening in an exchange of gunfire.

Officials say the suspect and a police officer were wounded.

Erika Murray, spokesman at Maryland's Prince George's Hospital Center, says the guard, identified as Lawrence Buckner, died there Thursday evening.

The officer and suspect were both conscious when taken for medical care, D.C. Police Chief Cathy Lanier told a news conference.

Lanier said events began after a guard at a gate of the U.S. Census Bureau in Suitland, Maryland, saw two people fighting in a car matching a description of a vehicle from a report of an armed kidnapping six miles away in northeast Washington.
