The following day, July 4, 2025, at approximately 2:30 PM, deputies initiated a traffic stop near the 2100 block of University Drive in Vista, contacting Isaac Mandujano (DOB: 12/5/2001). Mandujano had arranged to sell fireworks to undercover detectives, a violation of California Health and Safety Code section 12671.
During the stop, deputies discovered Mandujano was armed with a loaded 9mm Glock 17 handgun and an additional loaded magazine. Mandujano did not possess a permit to carry a concealed weapon and was arrested for violating Penal Code section 25400(A)(3) – carrying a concealed firearm in public.
A search incident to the arrest revealed multiple dangerous fireworks on the passenger seat of his vehicle. Deputies also located a container of marijuana, a water bong, and brass knuckles inside the vehicle. In a post-Miranda statement, Mandujano admitted to being under the influence.
Mandujano faces additional charges, including violations of Health and Safety Code section 11550 (E) (under the influence of a controlled substance while armed), Penal Code section 25850(A) (carrying a loaded firearm in public), Penal Code section 21810 (possession of brass knuckles), and Health and Safety Code section 12677 (selling dangerous fireworks). After a blood chemical sample was obtained, Mandujano was booked into the Vista Detention Facility.”
