Isaac Jammal Grant Sr., 42, was found with gunshot wounds inside a trailer in the Alta Vista neighborhood of San Diego on the night of January 27, 2021, and died at the scene. Detectives determined he had been shot multiple times and treated the case as a homicide.

Investigators interviewed witnesses, reviewed surveillance footage, and collected forensic evidence. In the months after the killing several leads were pursued and law enforcement identified a person of interest who reportedly had a contentious relationship with Grant and was believed to have been present at the scene, but no charges were filed and no arrest was announced.

Family and friends held vigils and rallies while the investigation remained open and authorities urged the community to come forward with any information that could assist the inquiry.

If anyone knew Isaac, his movements that night, or has information that could help the investigation, please share what you know with San Diego law enforcement.
