On the evening of July 24, 2026, officers in Syracuse responded to a residence on the 100 block of East Borden Avenue where 27-year-old Alvine Mamadjimbaye was found deceased. An autopsy by the Onondaga Medical Examiner’s Office the next day determined she died of a gunshot wound, and her death was ruled a homicide.

Investigators identified 35-year-old Hassan A. Muse as a suspect and allege the shooting occurred on July 23, 2026. A criminal complaint filed by a detective alleges Muse intentionally shot Mamadjimbaye in the neck while she was asleep in bed. Muse was arrested in the city’s Northside neighborhood without incident, arraigned in Syracuse City Court on charges including second-degree murder and criminal possession of a weapon, pleaded not guilty, and is being held without bail.

This is a domestic homicide where charges have been filed and the case is proceeding through the court system. Anyone who knew Alvine, her routines, or has information about what happened that night is asked to come forward.
