EXECUTIVE SUMMARY
A North Carolina grand jury indicted Sarah Santiago, 17, on three counts of first-degree murder and one count of conspiracy on August 31, 2026, for allegedly agreeing before the fact to publish the shooters' manifesto and distribute the livestream of the May 18 attack at the Islamic Center of San Diego. Two gunmen killed three people at the mosque and then took their own lives. Santiago is the first person charged in connection with the attack who was not physically present at the scene.
ANALYSIS
The May 18, 2026 attack at the Islamic Center of San Diego, the largest mosque in the San Diego area, killed three people: a security guard and two community members. The shooters, identified as Cain Lee Clark, 17, and Caleb Liam Vazquez, 18, also fired at a landscaper in a drive-by shooting near the mosque before killing themselves in a nearby neighborhood. The Federal Bureau of Investigation (FBI) designated the attack a hate crime. The Center for Strategic and International Studies (CSIS) subsequently described it as the first ideologically motivated lethal attack on a mosque in the United States in over two decades. A racist manifesto authored by the shooters, which explicitly referenced the 2019 Christchurch mosque shootings in New Zealand, was recovered online in the days following the attack.
On August 31, a Winston-Salem, North Carolina grand jury returned an indictment charging Santiago with three counts of first-degree murder and one count of conspiracy to commit first-degree murder. Prosecutors allege Santiago agreed in advance to publish the attackers' writings and to ensure the attack's livestream reached a wider audience. Under North Carolina law and the prosecution's theory of liability, Santiago's alleged pre-attack agreement to amplify the attack and its ideological materials constitutes participation in the conspiracy sufficient to support murder charges. She is the first person charged in connection with the San Diego attack who did not physically participate in the shooting.
