On the evening of June 24, 2021, 29-year-old Rien Green was fatally shot in a burst of gunfire outside a diner at Woodmore Towne Centre in Glenarden, Maryland. The attack occurred around 10:30 p.m. and wounded two other men; all three were taken to a local hospital, and Green died a short time later. One companion was reported in critical condition, the other treated and released.

Green was a licensed master barber who had opened his own shop, Clipollos Grooming, in the same shopping center. Friends and clients described him as ambitious and community-minded; he gave free haircuts to the homeless and worked to inspire young men. Prince George’s County Police Homicide Unit led the investigation and said they did not believe the shooting was random. As of late 2024 no arrests have been announced and the case remains unsolved.
