5 dead in attack at San Diego mosque; anti-Islamic writings are found, sources say

Authorities are investigating a deadly shooting at the Islamic Center of San Diego, the largest mosque in San Diego, as a possible hate crime after two teenage suspects opened fire outside the center on May 18, 2026. Three people, including a security guard who officials say likely prevented an even larger tragedy, were killed in the attack before the two suspects died from apparent self-inflicted gunshot wounds. Police said the suspects, ages 17 and 18, arrived wearing camouflage gear shortly before midday prayers and opened fire, prompting a massive law enforcement response.

Earlier that morning, the mother of one of the suspects had reportedly contacted police to report her son missing, suicidal, and in possession of several firearms taken from the home. Authorities are also investigating anti-Islamic writings allegedly connected to the suspects.

Additional Readings:

• Update from Special Agent in Charge Mark Remily on May 18 Shooting at the Islamic Center of San Diego
• Security guard warned teachers to lock doors during San Diego Islamic Center shooting
• What we know about the San Diego Islamic Center shooting suspects
• Suspect’s Mother Warned Police of Missing Guns Before Mosque Attack
• What we know about the San Diego shooting victims, suspects, possible motive and more

Analyst Comments: The attack on the Islamic Center of San Diego underscores the continued threat of anti-Muslim and Islamophobic violence targeting religious institutions and community gathering spaces in the United States. Although these incidents often receive less sustained public attention, threats and acts of violence directed at Muslim communities have periodically increased during periods of heightened geopolitical tension, including in the wake of the Israel–Hamas conflict and escalating tensions involving Iran. Incidents involving heavily armed individuals, pre-attack behavioral indicators, and extremist rhetoric reinforce the importance of timely threat reporting, information sharing, and layered security measures at mosques and other Islamic community facilities. Organizations and community leaders should continue encouraging the reporting of concerning behaviors, maintaining active emergency response plans, and coordinating with local law enforcement and security partners to strengthen preparedness against ideologically motivated targeted violence.

Copper theft leaves Missouri church facing expensive HVAC replacement

Members of St. Luke’s United Methodist Church are dealing with thousands of dollars in damage after thieves stole copper wiring and damaged multiple rooftop and ground-level HVAC units at the church. Surveillance footage reportedly captured a suspect climbing onto the roof and cutting copper from several air conditioning systems, with church members noting that older units were specifically targeted because they contain larger amounts of valuable copper. The damage is expected to require full replacement of several units and associated piping, creating significant repair costs and leaving the church without air conditioning as summer temperatures increase. Despite feeling violated and disappointed by the incident, church leaders said they are responding with compassion and are praying that those responsible find other ways to support themselves without harming the community.

Analyst Comments: The incident at St. Luke’s United Methodist Church reflects the continued threat of copper thefts targeting churches, schools, utilities, telecommunications infrastructure, and commercial facilities across the United States and internationally. Driven largely by the current price of copper , criminals target HVAC systems, electrical wiring, utility lines, and construction sites for quick resale at scrap yards.

Religious institutions and other community organizations may remain particularly vulnerable because HVAC units and external utility systems are often located in accessible areas with limited overnight security monitoring. Beyond the direct financial impact, these incidents can disrupt operations, create safety hazards, and strain already limited budgets for nonprofit and faith-based organizations. Organizations should consider reviewing physical security measures around HVAC systems and utility infrastructure, including surveillance coverage, lighting, fencing, alarm systems, locking mechanisms, and routine patrols.
