Officials say the suspect took off in a vehicle. A vehicle of interest was discovered during the investigation, possibly associated with the shooter, police say. The vehicle, a white colored Cadillac sedan with a partial California license plate of "7NP," was seen fleeing the scene.
At approximately 12:30 p.m., multiple reports came into Napa Dispatch about a Black man jumping fences and running through backyards. Napa County Sheriff's deputies and detectives responded and apprehended the suspect.
The suspect has been identified as 23-year-old Martinez resident Christopher "Roly" Young.
After an investigation, detectives found the white Cadillac used in the shooting parked on Cattail Drive. Surveillance video showed a male suspect matching Young's description parking and leaving the vehicle shortly after the shooting.
He then left the area on foot in the direction in which he was eventually apprehended by police. A search of the vehicle uncovered a .45 caliber handgun, the same caliber handgun used in the Safeway shooting.
Safeway released a statement saying, "Our team is fully cooperating with the American Canyon Police Department and Napa Couty Sheriff's office in their investigation into this tragic situation."
