A Forsyth County grand jury in Winston-Salem indicted 17-year-old Sarah Lindsey Santiago on August 31 on three counts of first-degree murder and one count of felony conspiracy, even though she was more than 2,000 miles from the Islamic Center of San Diego when three men were shot to death there. Santiago is not accused of pulling a trigger or providing a bullet during the May 18 attack in Clairemont. Prosecutors instead say she watched the massacre unfold on a livestream, helped spread it afterward, and mailed one of the gunmen a Nazi-linked patch he wore that day.
The case is moving through a North Carolina courtroom rather than a California one, and that jurisdictional choice is itself part of the story, according to The Mercury News. San Diego District Attorney Summer Stephan said the investigation involves agencies across multiple jurisdictions, and her office has said it is actively working with law enforcement partners to determine whether others can be held criminally liable. Santiago made her first court appearance on August 17 and was denied bond; her next hearing is scheduled for September 21.
Two teenagers, 17-year-old Cain Clark and 18-year-old Caleb Vazquez, arrived at the Islamic Center of San Diego on May 18 armed and wearing GoPro helmet cameras, according to Voice of San Diego, which reported the pair livestreamed the assault to three online viewers. They killed three congregants — 51-year-old security guard Amin Abdullah, 78-year-old caretaker and co-founder Mansour Kaziha, and 57-year-old member Nadir Awad — before both were later found dead in a car near the mosque in what investigators described as a double-suicide or murder-suicide, per the seed reporting. Roughly 140 people, many of them children, were on the grounds that day.
A Guard Who Bought Time For 140 People
Abdullah engaged the gunmen in a shootout that triggered a facility lockdown, preventing the shooters from reaching an area where the children were gathered, according to reporting cited by PBS. He died outside the sanctuary space after drawing gunfire away from worshippers inside. Forsyth County District Attorney Jim O'Neill said during the indictment announcement that Clark and Vazquez had also prepared plans to target two additional locations in San Diego — a Jewish temple and Black students at a public high school — a detail San Diego officials later clarified referred to students rather than a predominantly Black institution.
Investigators say Santiago agreed to record and disseminate the livestream footage and the shooters' written manifesto, and that she failed to warn authorities about the planned attack despite watching it happen. The indictment further alleges she purchased a patch bearing the Sonnenrad, a white-supremacist and neo-Nazi symbol, and mailed it to Vazquez, who wore it during the attack. Local sheriff's officials connected Santiago to an Eastern time zone IP address watching the livestream, leading to her arrest in Winston-Salem days before the school year started, the seed reporting states. Santiago's attorney has said his client is innocent of the charges.
Why North Carolina, Not California
The jurisdictional question at the center of this case comes down to how differently the two states handle minors accused of the most serious crimes. Under North Carolina General Statutes § 7B-2200.5, when a 16- or 17-year-old is indicted for a Class A felony such as first-degree murder, jurisdiction transfers automatically from juvenile court to adult Superior Court without a fitness hearing, according to the North Carolina Judicial Branch. The state's Raise the Age framework retained mandatory adult transfers for Class A through Class C violent felonies. Stephan has said North Carolina provides a more direct path to trying a minor as an adult, and O'Neill said his office secured the indictment after local and federal law enforcement approached his office about the case.
California law works differently. Welfare and Institutions Code § 707 requires that all criminal cases involving minors under 18 begin in juvenile court, and prosecutors must petition a judge and prove by clear and convincing evidence that the youth is not amenable to rehabilitation in the juvenile system before a case can move to adult court, the Mercury News reported. California also offers youthful offender parole under Penal Code § 3051, meaning people sentenced to at least 15 years for crimes committed before age 26 may be eligible for an earlier parole hearing. Duke University law professor Ronald Wright called the North Carolina case a new fact pattern, saying he found no prior North Carolina cases charging assistance offered before a murder committed in another state.
An Untested Theory Of Liability
Central to the prosecution is North Carolina's aiding-and-abetting doctrine, which provides that a person may be guilty of a crime without personally performing the acts that constitute it. Wright said North Carolina's aiding-and-abetting theories of liability are extremely broad, and that support making it more likely perpetrators will carry out a plan can establish aiding and abetting even without physical presence. O'Neill said a person need not be present in California to be an aider or abettor if that person shares the perpetrator's criminal intent and can render aid — a standard that, if upheld, would let a defendant sitting in a bedroom on the East Coast face the same first-degree murder exposure as someone who fired the shots.
Loyola Law School professor Donald Dripps said federal guidelines create a presumption against federal prosecution when state prosecution can adequately serve federal interests, which is part of why federal prosecutors favored funneling this case toward state court rather than federal juvenile proceedings. Santiago's prosecution is the first filed in connection with the mosque attack, and San Diego's district attorney has said justice will be served through the North Carolina court.
Warning Signs Before The Attack
Separately, the parents of gunman Caleb Vazquez filed a wrongful death and negligence lawsuit against Park Mental Health in San Diego on August 31, alleging the residential facility failed to intervene after the FBI notified it four days before the attack that Vazquez was plotting mosque shootings on the dark web, according to KPBS. Vazquez went missing from the Normal Heights residential facility the evening before the attack, the outlet reported. It remains unresolved how that civil litigation will ultimately address the alleged breakdown in monitoring.
A June 2026 report from the Institute for Strategic Dialogue concluded the San Diego mosque attack exemplifies an emerging fracture in neo-Nazi accelerationism, in which young perpetrators operate outside formal extremist networks and blend white-supremacist ideology with nihilistic online subcultures and livestreaming aesthetics. The Institute for Strategic Dialogue found that remote participants in these digital subcultures act as force multipliers by recording, archiving, and spreading attack propaganda. Investigators have said three people watched the attack livestream, and it remains an open question whether additional online viewers or digital accomplices will face criminal charges of their own.
The attack devastated Clairemont's Muslim community and rippled outward, prompting mosque security increases in cities as far away as Austin and a predawn scare near a Memphis mosque in the weeks that followed. In San Diego, the Padres held a sold-out MENA Night in August honoring Abdullah's community, a gesture of remembrance three months after the shooting. As Santiago's case heads toward its next hearing this month, the broader question of how far a state can reach to prosecute an out-of-state teen for a killing she never witnessed in person remains unsettled.
