On the evening of March 29, 2021, gunfire in a Glenarden, Maryland neighborhood left a man dead outside a residence on the 7900 block of Glenarden Parkway. Officers from Glenarden and Prince George’s County responded around 9:10 p.m. and found 31-year-old Anthony Lamont Frost of Washington, D.C., with multiple gunshot wounds; he was pronounced dead at the scene.

Prince George’s County Police Homicide Unit led the investigation. Detectives canvassed the area and interviewed potential witnesses, operating on a preliminary theory that the shooting was not random and that Frost and the shooter were previously acquainted. Investigators developed a suspect identified as 31-year-old Omar Parker of Mount Rainier; police say a dispute between Parker and Frost escalated into the fatal shooting.

Parker was located and arrested in Richmond, Virginia, and charged with first- and second-degree murder and other offenses. Anyone with information about Frost or the incident is asked to come forward.
