Sarah L. Santiago, a 17-year-old from North Carolina, has been indicted on three murder counts and one conspiracy count in connection with the May 18, 2026, shooting at the Islamic Center of San Diego. Prosecutors allege she helped record and distribute the attackers’ livestream and publish their manifesto, although she was not physically present in California. The shooting killed three men who confronted the gunmen and helped prevent further bloodshed. Authorities say the investigation has involved more than 100 interviews, over 30 search warrants and a review of more than 4 million messages.

Indictment follows allegations of online assistance
A grand jury in Forsyth County, North Carolina, indicted Sarah L. Santiago on Monday, according to court records and statements from prosecutors. She is accused of aiding and abetting murder through conduct linked to the shooting, as well as participating in a conspiracy.
Prosecutors allege that Santiago assisted the attackers by recording their livestream, distributing it and publishing their manifesto. The charges concern actions she allegedly took before and during the May 18 attack, rather than physical participation at the California crime scene. The allegations remain subject to the legal process.
Deadly attack at the Islamic Center of San Diego
Authorities say Caleb Vazquez, 18, and Cain Clark, 17, entered the Islamic Center of San Diego armed and intending to kill people. Three men, identified as Amin Abdullah, Nadir Awad and Mansour Kaziha, confronted the gunmen and were killed.
Police said the attackers later died by suicide in a nearby vehicle. Investigators have described the mosque as one part of a broader plan that also allegedly included a local Jewish temple and a predominantly African-American high school. The attack occurred on May 18, 2026, in San Diego, California.
“Their plan that day was to commit mass murders not only at the mosque, but to follow up at a local Jewish temple. And finally, at a predominantly African-American high school there in town,” District Attorney Jim O’Neill said.
Alleged agreement to record and spread material
The indictment alleges that Santiago agreed before the shooting to record and distribute the gunmen’s livestream and to publish their manifesto. Prosecutors also accuse her of buying a patch displaying a white-supremacist symbol for one of the attackers to wear during the shooting.
The alleged online role is central to the case because investigators say the material could help extend the attackers’ message beyond the locations where the violence occurred. Prosecutors have not alleged that Santiago was in San Diego when the shooting took place, but they contend that her communications and other actions connected her to the plan.
“She disseminated that information. And she published their manifesto,” Jim O’Neill said.
North Carolina jurisdiction and adult prosecution
Although Santiago was across the country in North Carolina during the attack, prosecutors said the state’s courts can pursue charges based on conduct allegedly carried out there. The district attorney said her physical absence from California does not remove the case from North Carolina jurisdiction.
North Carolina law allows a 17-year-old accused of this type of conduct to be treated as an adult, according to the district attorney. The indictment means a grand jury found sufficient grounds for the charges to proceed, but it does not establish guilt. Santiago will have the opportunity to contest the allegations in court.
“She didn’t have to be in California, she’s in our jurisdiction,” Jim O’Neill said. “And today, a grand jury indicted her and held her responsible for her actions leading up to that disastrous day in May.”
Investigation details and law enforcement response
The investigation has extended beyond the shooting scene and has included more than 100 interviews, over 30 search warrants and a review of more than 4 million messages. Those efforts have focused on the alleged planning, communications and distribution of material associated with the attack.
The FBI said investigators believe Santiago had several opportunities to contact law enforcement and warn authorities about the alleged plans. Reid Davis, the FBI’s Charlotte special agent in charge, said investigators viewed the failure to report the conduct as significant to the case.
“Our investigation shows that the individual had multiple opportunities to come forward to law enforcement and alert us of these deliberate actions, and the failure to do so must have consequences,” Reid Davis said.

Summary
The indictment expands the legal consequences of the San Diego mosque shooting to include an alleged remote facilitator in North Carolina.

The charges will now be tested through the criminal court process.
