Sarah Lindsey Santiago of Winston-Salem was indicted Monday on three counts of first-degree murder and one count of conspiracy to commit first-degree murder for allegedly aiding and abetting 17-year-old Cain Clark and 18-year-old Caleb Vazquez before and during their May 18 attack on the Islamic Center in Clairemont. Prosecutors allege Santiago had agreed beforehand to help preserve and spread the gunmen's violence by recording their livestream and distributing both the footage and a manifesto they wanted released to the public.
The charges raise an obvious question: How can a teenager 2,200 miles away, who never entered the mosque or fired a gun, be charged with murdering three people in San Diego? Prosecutors say Santiago wasn't merely watching from afar, she was part of the plan.
According to the indictment, Clark and Vazquez intended not only to carry out the massacre but to livestream it and spread their propaganda afterward. Authorities allege Santiago agreed beforehand to record the livestream, distribute the footage and publish their manifesto, then carried out those tasks. She is also accused of buying a patch bearing a white-supremacist symbol and sending it to one of the gunmen, who allegedly wore it during the attack.
Under North Carolina law, someone who knowingly aids or encourages another person in committing a crime can be held responsible for the crime itself. Simply knowing about an attack, watching it or failing to warn authorities would not ordinarily be enough; prosecutors must prove Santiago intentionally assisted the gunmen and shared the criminal intent necessary to commit the murders.
That makes Santiago's alleged agreement before the massacre crucial. Prosecutors contend spreading the attack online was part of Clark and Vazquez's plan from the beginning, making Santiago's alleged role part of the operation rather than assistance provided only after the killings. District Attorney Jim O'Neill said the gunmen wanted their "carnage and destruction" recorded, livestreamed and disseminated, and prosecutors allege Santiago agreed to help make that happen.
The indictment also reveals just how deeply investigators have penetrated the online network surrounding Clark and Vazquez since the shooting. FBI officials say investigators have conducted more than 100 interviews, executed more than 30 search warrants and examined more than four million messages during the continuing investigation.
Authorities say the two San Diego-area teenagers met online and became immersed in an extremist subculture before discovering they lived relatively close to one another. Their writings drew from neo-Nazi and white-supremacist ideology and expressed hatred toward Muslims, Jewish people, Black people, LGBTQ+ people, women and people across the political spectrum, while praising previous mass killers and discussing a desire to accelerate social collapse.
Monday's announcement revealed that their ambitions allegedly extended substantially beyond what actually happened at the Islamic Center. According to prosecutors, Clark and Vazquez intended to follow the mosque massacre with attacks on nearby Kehilat Ariel Messianic Synagogue and then a predominantly Black high school. Authorities have not publicly identified the school.
That planned sequence makes the intervention of Islamic Center security guard Amin Abdullah even more consequential. On May 18, Clark and Vazquez arrived heavily armed at the mosque at approximately 11:43am while roughly 140 people, many of them schoolchildren, were on the property. Abdullah recognized the threat, initiated lockdown procedures and exchanged gunfire with the attackers; authorities revealed Monday that Abdullah managed to shoot and wound Clark during the confrontation..
Abdullah was killed, along with 78-year-old Mansour Kaziha, a longtime founder and caretaker of the mosque, and 57-year-old Nadir Awad, who lived nearby and ran toward the Islamic Center after hearing gunfire. The attackers subsequently fled, fired at a landscaper several blocks away without striking him and were later found dead from self-inflicted gunshot wounds inside their vehicle roughly a half-mile from the mosque. Whatever plans they allegedly had for additional targets ended there.
The new indictment suggests, however, that the physical attack in San Diego was only one component of a digital operation extending far beyond Southern California. Authorities say Clark and Vazquez wore GoPro cameras to livestream the massacre, and investigators ultimately determined three people were watching the original livestream. Investigators initially knew little about one viewer beyond indications she was in the Eastern time zone; that trail eventually led to Winston-Salem and Santiago.
Exactly how Santiago allegedly met Clark and Vazquez, how long the three communicated, what their complete conversations contain and precisely when she learned an actual mass shooting was planned have not yet been publicly disclosed. Those questions will likely become critical as the prosecution moves forward, and her defense has already rejected the allegations.
"At this time, I can confirm that my client is innocent of all these charges," attorney Alan Doorasamy Sr. told the Associated Press, adding that he had not yet received the government's evidence concerning his client.
The prosecution will therefore ultimately have to prove not merely that Santiago interacted with two extremists, possessed abhorrent beliefs, watched their attack or distributed their material, but that her conduct and state of mind satisfy North Carolina's requirements for accomplice liability.
The geographic distance presents another unusual feature, but it does not necessarily prevent North Carolina from prosecuting the case. North Carolina law provides jurisdiction over certain offenses committed partly within and partly outside the state. If prosecutors prove Santiago entered the alleged agreement and performed her part of the operation from North Carolina, they have a basis for prosecuting her there even though the killings occurred in California.
Santiago's age presents another complication. She was 17 when the crimes occurred and is being prosecuted as an adult for Class A felony murder charges, but her age remains important at sentencing if she is convicted.
North Carolina's special juvenile-murder sentencing statutes would apply because Santiago was younger than 18 at the time. Depending upon the theory of conviction, a judge may have to conduct an individualized sentencing hearing before imposing life without parole, with youth-related mitigating circumstances considered. A juvenile sentenced to life with parole becomes eligible for parole after serving at least 25 years.
The decision to prosecute Santiago in North Carolina was itself deliberate. O'Neill said federal authorities evaluated the case but concluded the potential federal punishment for Santiago's alleged conduct could amount to only several years. Investigators instead approached Forsyth County prosecutors about pursuing charges under state law, where accomplice liability potentially exposes her to punishment for the murders themselves.
"The law in North Carolina is clear," O'Neill said Monday. A person who aids and abets another person in committing a crime, he said, can be found guilty of that crime even without personally performing the acts constituting it.
That theory explains why Santiago faces three murder counts rather than a single generalized charge related to the attack. Prosecutors contend she aided the underlying criminal enterprise that resulted in the deaths of Abdullah, Kaziha and Awad, with each death forming the basis of a separate murder allegation.
The case could become a consequential test of how traditional accomplice-liability principles apply to a distinctly modern form of mass violence in which alleged participants can occupy different roles across thousands of miles: gunmen at the physical scene, viewers receiving a livestream and online associates assigned to preserve or amplify propaganda connected to the attack.
It is equally important to distinguish that theory from criminalizing spectatorship. Authorities have said three people watched the initial livestream, and it remains unclear whether the other viewers have been identified or are suspected of participating in the plot. Nothing announced Monday establishes that simply viewing the stream would, by itself, expose someone to murder liability. The alleged advance agreement is what separates Santiago's case as prosecutors currently describe it.
But as investigators trace responsibility thousands of miles away from San Diego, newly disclosed allegations have also sharpened questions about what happened much closer to home during the final hours before the massacre.
According to a lawsuit filed by Caleb Vazquez's parents and first reported Monday by Times of San Diego, Vazquez was receiving mental-health treatment and living at a Park Mental Health residential facility in Normal Heights immediately before the shooting. The lawsuit alleges Vazquez simply walked out of that facility at approximately 8:24pm on May 17 - the night before the massacre - and his parents were not told he was missing until the following morning.
The allegation becomes considerably more significant because Park Mental Health allegedly knew authorities were already concerned about Vazquez. According to the lawsuit, clinicians were treating Vazquez for autism, obsessive-compulsive disorder, body dysmorphia, social anxiety and severe depression with psychotic episodes.

According to a lawsuit filed by Caleb Vazquez's parents and first reported Monday by Times of San Diego, Vazquez was receiving mental-health treatment and living at a Park Mental Health residential facility in Normal Heights immediately before the shooting. The lawsuit alleges Vazquez simply walked out of that facility at approximately 8:24pm on May 17 - the night before the massacre - and his parents were not told he was missing until the following morning.
The allegation becomes considerably more significant because Park Mental Health allegedly knew authorities were already concerned about Vazquez. According to the lawsuit, clinicians were treating Vazquez for autism, obsessive-compulsive disorder, body dysmorphia, social anxiety and severe depression with psychotic episodes.
On May 15, just three days before the shooting, his mother, Lilliana Vazquez, allegedly told his therapist that the FBI had contacted her after discovering Vazquez had been discussing school shootings and suicides on the "dark web." Park Mental Health's program contacted her that same evening to discuss the FBI's concerns, according to the complaint.
Despite that warning, the lawsuit alleges Vazquez left the Normal Heights residence two nights later without staff stopping him or promptly notifying his family. On the morning of May 18, according to the lawsuit, a Park Mental Health program director texted Vazquez's mother asking, "Do you have an idea of where Caleb could be?"
"Are you saying that he's missing?" she responded.
"Yes," the director allegedly replied.
Vazquez's parents say they drove to the Normal Heights residence at approximately 9am and were shown surveillance footage depicting their son pacing inside the home before leaving the property around 8:24 the previous night. They subsequently drove to Park Mental Health's North Park headquarters, where the lawsuit alleges the program director declined to meet with them and another employee instructed them to file a missing-person report.
When Lilliana Vazquez asked why nobody had notified her that her son disappeared the night before, the lawsuit alleges she received no answer.
Park Mental Health did not respond to Times of San Diego's request for comment on the lawsuit. The allegations have not been adjudicated, and the filing represents the Vazquez family's account of what occurred.
The timeline is nevertheless extraordinary. At approximately 9:42 that same morning, Clark's mother called San Diego police to report her son missing. About an hour later, she contacted police again after discovering weapons were gone from her home and finding what appeared to be a suicide note, prompting SDPD to elevate its search based on the possibility of violence.

About an hour later, she contacted police again after discovering weapons were gone from her home and finding what appeared to be a suicide note, prompting SDPD to elevate its search based on the possibility of violence.
Meanwhile, Caleb Vazquez's parents were searching for their son and attempting to obtain information from his treatment provider. According to the lawsuit, they left Park Mental Health's offices around 11:45am to return to Chula Vista. At 11:43am, two minutes earlier, San Diego police received the first report of an active shooter at the Islamic Center.
The lawsuit adds a previously unknown final chapter to a trail of warning signs surrounding Vazquez that stretched back more than a year. In January 2025, two of Vazquez's classmates approached administrators at High Tech High Chula Vista after he allegedly warned them not to attend school, suggesting he might be planning a mass shooting. School administrators contacted Chula Vista police, whose subsequent investigation documented an extensive fascination with mass killers and extremist ideology.
According to court records, school officials reported that Vazquez had come to school dressed as Dexter Morgan, the fictional serial killer from the television series Dexter, talked about a "day of retribution," pointed a banana at students while pretending it was a firearm and shaved his head in an apparent effort to resemble people in concentration camps. He reportedly expressed fascination with the perpetrators of mass killings in Poway, Isla Vista, El Paso and Norway and told authorities he idolized Adolf Hitler and researched mass shooters online.
Chula Vista police described Vazquez at the time as being involved in "suspicious behavior idolizing Nazis and mass shooters." A detective wrote that Vazquez's father was "uncooperative" during the initial welfare check, would not allow police to interview his son alone and would not permit officers to view social-media posts that Vazquez's friends had described as concerning.
Vazquez was ultimately placed on a 72-hour involuntary psychiatric hold, while police sought a gun-violence restraining order involving firearms kept by his father. His parents subsequently removed their guns, ammunition and sharp knives from the home, with records indicating the firearms were transferred to a licensed dealer for storage. Published accounts have variously described 26 or more firearms involved; the family's own court filing listed 27 belonging to Marco Vazquez and two belonging to his wife.
But the legal restriction did not last. On March 11, 2025, Superior Court Judge Enrique Camarena rescinded the temporary gun-violence restraining order and dismissed the matter without prejudice, according to the court minute order obtained by Times of San Diego. Previously published records did not explain why a permanent order was not granted.
Vazquez's parents have said publicly that they recognized their son's deteriorating condition, increased supervision, monitored his internet use, kept him in therapy and placed him in multiple treatment programs. After the shooting, they said their son was on the autism spectrum and had become consumed by hateful rhetoric and extremist propaganda online, while emphasizing that his circumstances provided no excuse for what he ultimately did.
"We will forever live with the burden of wondering whether there was more we could have done to help prevent this senseless tragedy," the family said after the attack.
The new lawsuit significantly expands that chronology. If its allegations are accurate, Vazquez was not simply a troubled teenager whose prior warning signs had faded from institutional view by May 2026. He was living in a mental-health treatment facility when, three days before the massacre, his mother allegedly told his therapist that the FBI had just contacted her about his discussions of school shootings and suicide online. Then he disappeared.
The lawsuit does not establish that Park Mental Health knew Vazquez was planning the Islamic Center attack, that staff could have predicted precisely what he would do after leaving or that preventing him from leaving necessarily would have prevented the massacre. Nor does the filing establish liability; Park Mental Health has not yet publicly presented its account of the events described by the family. What it does add is another documented point at which concerns about Vazquez's potential for extreme violence intersected with an institution responsible for his care shortly before the attack.
Those revelations also complicate the broader question of missed opportunities surrounding May 18. Schoolmates had previously sounded alarms. High Tech High administrators contacted police. Chula Vista police investigated. A psychiatric emergency team evaluated Vazquez. A gun-violence restraining order was obtained and later dismissed. His family removed firearms and pursued treatment. And, according to the new lawsuit, the FBI raised fresh concerns about discussions of school shootings just days before he walked away from a residential treatment facility. None of those interventions ultimately prevented Vazquez from meeting Clark and reaching the Islamic Center.
Santiago's arrest, meanwhile, sheds new light on the extraordinary volume of digital evidence investigators have been processing since May. When San Diego and federal officials initially described Clark and Vazquez as teenagers radicalized online, the extent to which they had communicated with like-minded people elsewhere remained largely unknown. Santiago's indictment is the first publicly announced arrest of another person allegedly connected to the attack.
Imam Taha Hassane has said mosque leaders long suspected the shooters were not operating entirely in isolation and welcomed the North Carolina arrest while urging investigators to determine whether others were involved. The Islamic Center subsequently told its community that Santiago's indictment did not represent a new threat and that the mosque remains open and operating normally.
Whether the evidence proves the allegations against Santiago beyond a reasonable doubt will ultimately be decided in court. She maintains her innocence through counsel, the complete communications underlying the prosecution have not been released, and an indictment establishes allegations rather than guilt.
Santiago is being held without bond and is scheduled to return to court September 21.
For the Islamic Center of San Diego, the developments on opposite sides of the country expose two strikingly different pieces of the same investigation. In North Carolina, prosecutors are reaching 2,200 miles away to argue that someone who never entered the mosque can bear criminal responsibility for three murders because of what she allegedly agreed to do online before the attack. Back in San Diego, a civil lawsuit now alleges one of the men who actually carried out those murders disappeared from a mental-health residence less than 16 hours before the shooting, days after the FBI had raised concerns about his discussions of school shootings and suicide.
Abdullah, Kaziha and Awad were killed, but approximately 140 people at the Islamic Center survived, and prosecutors now say Clark and Vazquez never reached the additional targets they allegedly intended to attack.
The investigation that began in a Clairemont parking lot has since expanded through millions of messages, dozens of search warrants, a murder prosecution across the country and now a civil lawsuit examining the final hours before one gunman arrived at the mosque.
Three months later, investigators are still discovering how many people and institutions crossed paths with the two teenagers before May 18 and how many opportunities may have existed to recognize what was coming.
This is a developing story and will be updated as additional information becomes available.
