Sarah Lindsey Santiago, 17, may face life behind bars after being accused of assisting two teenage gunmen who carried out the deadly San Diego mass shooting on 18 May. Santiago allegedly livestreamed the attack and distributed the gunmen's extremist manifesto.

The North Carolina teenager was indicted by a grand jury on Monday, 31 August, on three counts of murder and one count of conspiracy. Santiago wasn't present at the mosque during the attack, but prosecutors allege that Santiago agreed beforehand to record the shooting.

Santiago also agreed to distribute the captured video and publish writings produced by the attackers. Even though she wasn't physically at the crime scene, under North Carolina law, people who aid and abet a crime can face the same penalties as those who commit the crime themselves, according to Forsyth County district attorney Jim O'Neill

Three Heroes, One Injured, Two Attackers Dead

The shooters, identified as 17-year-old Cain Clark and 18-year-old Caleb Vazquez, entered the Islamic Centre of San Diego on 18 May 2026. They were reportedly heavily armed as they approached the mosque before opening fire.

Approximately 140 children were at the Islamic Center's school when the attack began, but fortunately, a security guard named Amin Abdullah was there to exchange gunfire with the shooters while initiating a lockdown.

Abdullah, alongside caretaker Mansour Kaziha, 78, and Nadir Awad, 57, the husband of a teacher at the centre, was killed during the attack. The three men were later hailed as heroes for helping protect the children.

As the gunmen fled the area, they also shot at an unidentified landscaper, who suffered minor injuries. The two suspects were eventually found dead inside a vehicle after shooting themselves.

Santiago's Role in the Shooting

According to the prosecution, Santiago's involvement involves more than simply recording the shooting. O'Neill said at a news conference, 'The individual here, locally, was the person who was recording the livestream.' He added that she 'disseminated the footage, and published their manifesto.'

The manifesto in question reportedly contained extremist hatred directed at multiple groups, even citing the 2019 Christchurch mosque shootings in New Zealand as the inspiration for their actions.

O'Neill also described the attackers as part of an 'underground subculture' in which people communicate on encoded platforms.

District Attorney O'Neill stated, 'Cain and Vazquez, by what is contained in their manifesto, seemed to hate everyone, regardless of skin colour, politics, religion, or ethnicity.' He also elaborated that the purpose of the livestream done by Santiago was to 'memorialize the two terrorists.'

Santiago's Possible Life Behind Bars

Investigators determined that three people had watched the livestream of the attack. Authorities initially knew that one of the viewers was a woman located in the Eastern US time zone before eventually identifying her as Santiago, according to prosecutors.

Investigators subsequently linked her to the livestream and arrested her in North Carolina shortly before the start of the school year.

Santiago's attorney, Alan Doorasamy Sr., has maintained that his client is innocent of the charges. Santiago remains legally presumed innocent unless and until she is found guilty in court.

If convicted, Santiago could face life imprisonment without the possibility of parole. Authorities opted to pursue state charges because she can be prosecuted as an adult in North Carolina.
