What we know about the San Diego shooting victims, suspects, possible motive and more
Two teenage gunmen are believed to have killed three people at a San Diego mosque Monday before they took their own lives, authorities said.
Investigators are working to determine a motive, but the San Diego police chief said the violence was being investigated as a possible hate crime.
Chief Scott Wahl said the event was “every community’s worst nightmare.”

Here’s what we know about the shootings.
The victims
Authorities responded to a report of an active shooter at the Islamic Center of San Diego, described on the center’s website as the largest mosque in San Diego County, at 11:43 a.m., Wahl said.
The mosque is in San Diego’s Clairemont neighborhood, roughly 8 miles north of downtown.
Officers arrived four minutes later and found three men dead in front of the mosque, Wahl said.
One of the men was a security guard who Wahl said was “pivotal” in preventing more bloodshed.
“At this point, I think it’s fair to say his actions were heroic,” Wahl said. “Undoubtedly, he saved lives today.”
The victims were not identified Monday.
An imam from the Islamic Center said all teachers, students and other school staff members who were at the mosque were safe.
As the officers deployed what Wahl described as an active shooter response at the mosque and at an adjacent school, more gunfire was reported blocks away, he said.
A landscaper who was working in the area was shot at but not struck, Wahl said.
Where were the suspects found?
Less than a quarter-mile from the landscaper, police found a vehicle in the middle of the street with the two teenagers believed to be the shooters inside, Wahl said.
Both are believed to have died by self-inflicted gunshot wounds, he said.
Two senior law enforcement officials briefed on the investigation and a federal law enforcement official identified the suspects as Cain Clark, 17, and Caleb Vazquez, 18.
Clark attended high school virtually, but was set to graduate later this month, according to a school district official.
The mother of one of the suspects called police Monday morning and said her son, her firearms and her car were missing, Wahl said.
She described the teen as suicidal and said he was most likely with a friend, Wahl said. Both were wearing fatigues, he recalled her saying.
Officers were talking with the woman and trying to piece together where her son might be when they learned what was happening at the Islamic center, Wahl said.
They “immediately dispatched themselves to the mosque,” he said.
What we know about a possible motive
The mother told police that her son left a note, Wahl said. He declined to provide additional details about it.
Wahl said “hate rhetoric” was involved in the shooting, which he said is being investigated as a hate crime. Investigators are examining possible anti-Islamic writings found in the teens’ car, two senior law enforcement officials said.
An imam with the mosque, Taha Hassane, said the center had never before experienced a tragedy like Monday’s shooting, and he said it is “outrageous” that someone would target a place of worship.
“People come to the Islamic center to pray, to celebrate, to learn,” he told reporters.
Monday was the first day of Dhul Hijjah, the last month of the Islamic calendar and one of its most sacred periods.
In a news release, the mosque said it will remain closed until further notice.

Why this matters
Located in neighborhoods across the county, community gardens seek to provide resources and educational opportunities for people of all ages and backgrounds.

Tucked into neighborhoods, schoolyards and park edges, community gardens have woven themselves into the fabric of San Diego.
Many are established in food deserts – areas that lack access to affordable and nutritious food. For predominantly low-income and racially diverse communities, a local garden plot can be the difference between having fresh produce or none at all.
Beyond the food, community gardens have become gathering places where social bonds across generations and languages form and environmental education can flourish. From elementary school students to senior citizens, people of all ages are able to tend to plants or participate in community activities hosted onsite.
San Diego County has more than 80 community gardens, according to the Master Gardener Association of San Diego County. Most of them are managed by churches, nonprofits or local volunteers.
However, funding may be running short. The One, Big, Beautiful Bill Act led the county to cancel contracts related to CalFresh Healthy Living in October 2025, as previously reported by inewsource. Community gardens were one of the lifestyle programs impacted by these cuts.
Nonprofit leaders have also sounded the alarm about federal cuts causing funding instability that could impact their community programs.
But there are still ways for the community to get involved. Here’s a map maintained by the Master Gardener Association that shows dozens of gardens around the county.
inewsource asked Heather Holland, president of the Master Gardener Association of San Diego County, and Julia Rauner Guerrero, the organization’s community garden chair, to talk about the basics of community gardens.
Answers have been edited for clarity and brevity.
Community gardens vary based on who owns the land but most gardens are spaces where renters of the garden beds have access during set hours. Most gardens have events or times where they open their doors to the public.
Community gardens are spaces where the public can garden or learn about gardening together. There are a few categories of community gardens that could be grouped this way:
- Gardens that include beds or spaces that can be rented for growing.
- Gardens that grow food that is donated to others.
- Gardens that act as learning spaces so the public can learn how to garden together.
- Semi-public spaces where someone from an area (as in a resident of an HOA) can garden in a space.
Most of San Diego’s community gardens fall into one of those categories and often include several of these characteristics. On our community garden map we’ve focused on gardens with individual or shared/cooperative plots, some of which also incorporate education and/or food sharing with the community.
No, generally there isn’t any registration with the county and the cities operate under different rules. Community gardens located on public land have different approaches dictated by their city. For example, in the city of San Diego nonprofit groups can apply to the city to use parks and recreation land for a community garden.
Community gardens are operated by a mix of persons depending on who is running the site. In most cases it is a church, a nonprofit or a group of volunteers who manage the space. A few San Diego cities such as Imperial Beach, Carlsbad and La Mesa oversee their gardens and in other cases the County of San Diego directly operates the community gardens on their property.
Volunteer at your nearby community garden to get a feel for the garden, the people and the management.
