Vallejo police arrested a man attempting to bring a concealed firearm into a high school graduation ceremony, just days after a fatal shooting at a similar event in Fairfield. - The suspect was observed by officers displaying behaviors consistent with carrying a concealed firearm, including a weighted L-shaped bulge under his clothing.
- He became hesitant upon seeing security screening and metal detectors, then returned to his vehicle to store belongings before being detained. - A loaded, unregistered handgun with an extended magazine was recovered from a backpack in his vehicle.
