On the morning of Sunday, July 19, 2026, 38-year-old Marius Munyamahoro was shot in an apartment in the 1100 block of Columbine Street, a residential area near Denver’s Congress Park. Emergency responders took him and another man to a hospital; the other man suffered non-life-threatening injuries, while Munyamahoro later died of his wounds and was memorialized in an obituary.

The Denver Police Department opened a homicide investigation and focused on a person believed to be known to the apartment’s occupants. On the Friday after the shooting, authorities arrested 29-year-old Jacob Anglon and held him for investigation on charges that include first-degree murder for Munyamahoro’s death and attempted murder for the injured man. Officials have described Anglon as an acquaintance of the victims but have not released a motive or detailed information about their relationship.

Anyone who knew Marius, the apartment’s occupants, or who has information about the July 19 shooting in the 1100 block of Columbine Street is asked to come forward.
