San Diego homicide detectives are investigating after a 49-year-old man was fatally shot at an independent living facility in Oak Park Saturday night. Police responded to a call for assault with a deadly weapon around 10:20 p.m. on 54th Street near Redwood Street. The victim had been shot once in the torso, Lt. Lou Maggi said in a statement. First responders performed CPR and took him to a hospital, but the man succumbed to his injuries, Maggi said. Police interviewed at least nine people who were at the facility and were trying to determine exactly where the shooting took place. Investigators planned to collect and review security video from the area, Maggi said. Police have not yet released any suspect description or said what might have led up to the shooting. “We don’t believe this was a random act,” Maggi told OnScene.TV.
