Officers also observed the suspect “repeatedly adjusting the object, holding it against his body while walking, and checking it with his hand to ensure it remained concealed.”\n\nOfficers then observed the male suspect become hesitant after noticing the event’s security screening area and metal detectors in front of the Corbus Field entrance. The suspect then returned to a nearby vehicle, where officers later observed him place personal belongings inside before returning to the graduation ceremony.\n\nOfficers detained the suspect and recovered a loaded firearm from a backpack found in the vehicle where the suspect had stored his belongings. The unregistered firearm was equipped with an extended magazine.\n\nPolice say the suspect, an Antioch resident, was not legally allowed to possess the handgun due to his age. The suspect was arrested and booked into the Solano County Jail.\n\n“Any time we take an illegal firearm off the streets, there is a sigh of relief,” said Public Information Officer Rashad Hollis. “Vallejo has seen a decrease in gun violence and homicides lately, and this recent policing is a testament to that.”\n\nPolice still do not have a suspect in custody from the shooting at the ceremony in Fairfield. Fairfield police are seeking the public’s assistance and asking anyone who may have information, photographs, videos, or other recordings related to the incident to share. The department is particularly interested in any media captured before, during, or immediately after the shooting, including:\n\n- Cell phone photographs or video recordings\n- Vehicle or dash camera footage\n- Residential or business surveillance video\n- Doorbell camera recordings\n- Any other audio, video, or digital evidence that may assist investigators\n\nAnyone with information is encouraged to contact the Fairfield Police Department through the following dedicated tip channels:\n\n- Text-A-Tip: Text: TIP FAIRFIELDPD followed by your message to 888777\n- Email tips: juneincidenttips@fairfield.ca.gov\n- Tip Phone Line: (707) 428-7345", "url": "https://wpnews.pro/news/east-bay-man-arrested-attempting-to-carry-firearm-into-high-school-graduation", "canonical_source": "https://www.mercurynews.com/2026/06/16/suspect-arrested-attempting-to-carry-firearm-into-vallejo-high-graduation-2/", "published_at": "2026-06-16 13:49:55+00:00", "updated_at": "2026-06-16 13:52:16.985473+00:00", "lang": "en", "topics": ["ai-safety"], "entities": ["Vallejo Police Department", "Vallejo High School", "Corbus Field", "Solano County Jail", "Fairfield Police Department", "Rashad Hollis"], "alternates": {"html": "https://wpnews.pro/news/east-bay-man-arrested-attempting-to-carry-firearm-into-high-school-graduation", "markdown": "https://wpnews.pro/news/east-bay-man-arrested-attempting-to-carry-firearm-into-high-school-graduation.md", "text": "https://wpnews.pro/news/east-bay-man-arrested-attempting-to-carry-firearm-into-high-school-graduation.txt", "jsonld": "https://wpnews.pro/news/east-bay-man-arrested-attempting-to-carry-firearm-into-high-school-graduation.jsonld"}}
