The first involved 48-year-old Ronald Anderson on April 9, 2015. On his birthday he allegedly abducted his girlfriend in Washington, D.C., then drove to the U.S. Census Bureau headquarters in Suitland, Maryland, where an altercation ended with a security guard fatally shot. A large police response led to a high-speed chase back into Washington, D.C., and a shootout in which Anderson was critically wounded, taken into custody, and hospitalized. He was later charged with murder and kidnapping and was indicted by a federal grand jury by October 2016; he remained in medical care while detained.

A separate case concerns a different Ronald Anderson, age 25, who was shot and killed around 12:15 a.m. on July 1, 2006, on the 2000 block of Maryland Avenue NE in Washington, D.C. That case remains unsolved and no arrests have been announced.

If anyone has information about the 2006 killing or the 2015 shooting at Suitland, please come forward to assist investigators.
