On a Thursday evening in March 2015, 64-year-old Santos Rafael Zelaya was killed in his home in the Alexandria section of Fairfax County, Virginia. Three armed men forced their way into the residence on North Kings Highway. While one intruder held Zelaya’s roommate at gunpoint, the other two searched the house. Zelaya confronted the intruders with a machete and wounded one of them, and was then shot multiple times. He was airlifted to a local hospital but died of his wounds.

Investigators did not believe the attack was random. Over the following months authorities identified four suspects. Gregory Brown, then 23, of Washington, D.C., and Niziah Williams, 24, of Clinton, Maryland, were arrested first and charged with murder. In March of the following year Timothy Lamont Washington, 20, of Alexandria, was arrested and charged with murder, and shortly after Eric Howard Buckner, 23, of Alexandria, was arrested and charged with second-degree murder.

Did anyone in Alexandria at the time see activity near North Kings Highway that night or know any details about these suspects’ movements?
