A lethal shooting on the night of Thursday, July 30, 2026, left 44-year-old Dolores Leiva Hernandez dead inside an apartment in the 5400 block of Kenilworth Terrace in Riverdale Park, Maryland. Police arrived about 10:15 p.m. after reports of a shooting and found Hernandez with fatal gunshot wounds; he was pronounced dead at the scene. The Prince George’s County Police Department Homicide Unit is handling the investigation.

A 34-year-old Riverdale Park resident, Noe Castillo-Mendez, was arrested shortly after the incident and has been charged with second-degree murder and related offenses. Reports say Castillo-Mendez and Hernandez were acquainted; investigators have not publicly described a motive or the events that led to the shooting. Federal officials also noted Castillo-Mendez’s immigration status and a prior 2025 drug possession arrest, which has drawn wider attention to the case.

Anyone with information about the shooting or the relationship between Hernandez and Castillo-Mendez is asked to contact detectives.
