Murder charge filed after deadly shooting in Riverdale Park
Prince George’s County police charged a Riverdale Park man in a July 30 apartment shooting that killed Dolores Leiva Hernandez, 44.

Prince George’s County police charged Noe Castillo-Mendez, 34, of Riverdale Park, with second-degree murder and related charges after a shooting that left Dolores Leiva Hernandez, 44, dead inside a Riverdale Park apartment.
The case places a homicide in one of Prince George’s County’s closely watched communities and gives residents a named suspect and a formal murder charge to follow. It also marks the point where investigators moved the case from the initial response phase into the criminal court process.

Police said the shooting happened July 30 inside an apartment in Riverdale Park. Hernandez, who also lived in Riverdale Park, died from the gunfire, while Castillo-Mendez now faces the most serious charge tied to the killing.

For neighbors and other county residents, the key facts now are the location, the date and the charge: a fatal shooting in a residential building, a 34-year-old suspect from the same town, and a murder case that is no longer just an open police inquiry. The filing does not answer every question about how the shooting unfolded, but it does show investigators had enough evidence to bring the case forward.

Riverdale Park sits in northern Prince George’s County, where apartment complexes, residential streets and busy corridors put violent-crime cases under close public scrutiny. This homicide adds another serious case to the county’s public-safety ledger and will now proceed through the courts under the second-degree murder charge and related counts.
