A graduation ceremony in California ended in tragedy on Wednesday evening after a shooting in a school parking lot left one person dead and three others injured, authorities said.

The incident occurred on June 3 at Fairfield High School, where a graduation event for Sem Yeto High School had just concluded. According to the Fairfield Police Department, officers were dispatched to the scene at approximately 7:15 p.m. local time following reports of gunfire in the parking area where families and students were gathered to celebrate the end of the ceremony.

Police confirmed that the victims included an 18-year-old who was pronounced dead at the scene, along with three other individuals aged 11, 20, and 25 who were transported to nearby hospitals for treatment. Officials have not yet released updates on the conditions of the injured victims, and their identities have not been made public.

Authorities said the shooting took place shortly after the graduation ceremony had ended at Sem Yeto High School, which was hosted on the same campus as Fairfield High School. The celebration, which had drawn students, families, and staff together in what should have been a moment of achievement and pride, quickly turned into chaos as gunfire erupted in the parking lot.

Witnesses described a scene of panic as attendees attempted to flee the area. Some reported hearing multiple shots fired before realizing what was happening, prompting crowds to run in different directions in search of safety. Parents were seen rushing to locate their children, while others attempted to shelter in place inside the stadium and nearby buildings.

Officials said emergency responders arrived quickly after receiving multiple 911 calls reporting the shooting. Officers secured the area and began treating victims before paramedics transported the injured to hospital. Despite rapid response efforts, one victim succumbed to their injuries.

At a press conference following the incident, Officer Michelle Belyea of the Fairfield Police Department described the situation as deeply distressing for the community, particularly given the timing at the end of a school-related celebration.

“It’s a very scary incident when something like this does happen, especially during the end of a school event,” she said. “We just want everyone to be safe.”

Belyea confirmed that investigators do not yet have any suspect information and said no arrests have been made in connection with the shooting. However, she emphasized that there is currently no indication of an ongoing threat to the public.

“We don’t have any information related to suspects at this time,” she said, adding that the investigation remains active and ongoing.

The shooting prompted a swift response from local officials, including Suisun City Mayor Alma Hernandez, who posted about the incident on social media as details were still emerging. She described an “active shooter chase” and confirmed that multiple individuals had been struck during the attack in the parking lot area of the graduation venue.

“This is an active investigation,” she wrote. “Our hearts go out to the families of the victims. Anyone with information is urged to contact the Fairfield Police Department.”

Authorities later clarified that while initial reports indicated urgency and confusion at the scene, there was no confirmed ongoing pursuit linked to a suspect at the time of the statement.

Despite the absence of arrests, law enforcement officials reiterated that there is no continuing danger to the community. Officers remained on site for several hours after the shooting to collect evidence, interview witnesses, and secure the perimeter as investigators worked to reconstruct the sequence of events.

The victims included individuals spanning multiple age groups, highlighting the indiscriminate impact of the violence. Among them was an 11-year-old child, whose presence underscored the fact that families, including young children, were gathered at the graduation celebration when the shooting occurred.

The incident has left the Fairfield community shaken, particularly as it unfolded during what was meant to be a milestone event for graduating students. Parents and attendees described confusion and fear as the celebration abruptly gave way to emergency response activity.

One witness, identified only as Jacob, described the moment gunfire erupted near a photography area set up for graduates and families.

“Out of nowhere, some dude ran up, and when I looked up, he pointed the gun and started shooting,” he said. “I backed up, he ran, and I just went around. My mom was back in the stadium, so I went to make sure she was OK.”

Another attendee, Lizette Ramirez, recalled hearing the shots while moving through the parking lot area.

“I don’t know what happened,” she said. “I’m coming to the parking lot when I hear the shots. I see my niece, my mom, and she say, ‘Run! run!’”

The Fairfield Police Department has not released any details about a possible motive for the shooting. Investigators are currently reviewing surveillance footage, collecting ballistic evidence, and speaking with witnesses to determine how the incident unfolded and whether the victims were specifically targeted or caught in a broader act of violence.

Law enforcement officials have also not confirmed whether the shooter fled the scene on foot or by vehicle, and no suspect description has been officially released.

Community leaders have expressed concern about the impact of the shooting on students and families who were present during the graduation ceremony. Mental health support services are expected to be made available in the coming days as the school district works to support those affected.

The Fairfield-Suisun Unified School District has not yet issued a detailed public statement regarding the incident, but officials are expected to coordinate with law enforcement as part of the ongoing investigation.

Sem Yeto High School, which operates as a continuation school on the same campus as Fairfield High School, was also impacted by the incident, as many of its students and families were present for the graduation ceremony being held at the shared facility.

As investigators continue their work, authorities are urging anyone with information about the shooting to come forward. They have emphasized that even small details could help identify those responsible and provide clarity about what led to the deadly violence.

For now, the community is left grappling with the aftermath of a celebration turned tragedy, as families mourn the loss of an 18-year-old life and pray for the recovery of the injured victims.

Officials say updates will be provided as more information becomes available, while law enforcement maintains an active presence in the area to reassure residents and continue the investigation into the attack.
