A second man has been arrested in connection with the fatal shooting of a 37-year-old Northwest Washington man in January, who police say may have been killed because of drug dispute.

Eugene Ledex Sherman, 53, of Southeast, was arrested just after 5 p.m. Saturday and charged with first-degree murder in the slaying of Matthew Shevlin. Shevlin was found shot outside his Mount Vernon condo on Jan. 22, and later died at a hospital.

Sherman joins 18-year-old David Davalier Harvey, who was arrested at the scene a few minutes after police found Shevlin. Harvey has been charged with first-degree murder and carrying a gun without a license.

Around 10:30 a.m. on Jan. 22, police responded to reports of gunshots in the 400 block of M Street NW, and when they arrived, found Shevlin in the courtyard of his apartment complex suffering from gunshot wounds to the head and chest. Police said when they arrested Harvey at Shevlin’s residence, he had a jar filled with marijuana that was labeled “White Fade Out.” After searching Shevlin’s apartment, police found numerous other jars filled with marijuana that were similar to the one Harvey had.

Surveillance video from the time of the incident shows three men approach Shevlin’s apartment, and later shows Shevlin running away from a man carrying a gun, police said.
