4 guns from Mother's Day murder of 10-year-old linked to another 28 shootings, 2 homicides

Shell casings recovered from the scene of the Mother’s Day murder of 10-year-old Arianna Davis came from four guns linked to more than two dozen other shootings, including two unsolved homicides, court documents revealed.

The 61 shell casings entered into the Bureau of Alcohol, Tobacco, Firearms and Explosives’ ballistic comparison database told police the four guns were used in 28 shootings in D.C. and Prince George’s County, Maryland, including the killings of 19-year-old Corey Riggins Jr. in November 2022 and Tyrone Hopkins in April 2023 — a few weeks before Arianna was killed.

In May 2022, a shot was fired in a robbery on Quincy Street NW. Police determined that shell casing came from one of the four guns linked to last year’s Mother’s Day murder.

D.C. police closed just three of those other shooting cases.
