A 17-year-old girl from North Carolina has been charged with murder by aiding and abetting after prosecutors said she recorded a live video of an attack on a San Diego mosque that left three people dead. Prosecutors stated that the girl also shared a manifesto written by two teenage gunmen who carried out the attack at the Islamic Center of San Diego on May 18. The teenager was arrested last week and indicted by a grand jury on Monday, according to Forsyth County District Attorney Jim O'Neill. O'Neill said during a news conference that the girl faces three murder charges and one count of conspiracy. In North Carolina, someone accused of aiding and abetting a crime can be held legally responsible in the same way as the person who committed the crime. The attack was carried out by two teenage males, aged 17 and 18, who opened fire at the mosque before taking their own lives. O'Neill said the attackers had two main goals: to kill as many people as possible and to have the violence recorded and livestreamed. A security guard at the mosque, Amin Abdullah, exchanged gunfire with the attackers and initiated a lockdown, helping to protect around 140 children inside the building. Abdullah, along with two worshippers—Mansour Kaziha and Nader Awad—who drew the shooters’ attention in a parking lot, were fatally shot. San Diego Police Chief Scott Wahl praised Abdullah's actions as "heroic," saying they "undoubtedly" saved lives. Investigators said the attackers used cameras mounted on GoPro-style helmets to record the attack. O'Neill stated that the pair had also planned additional attacks, including one at a local Jewish temple and another at a predominantly African American high school. Authorities said the teenagers had access to around 30 guns and a crossbow, which were taken from one of the shooters’ parents. The attackers left behind writings that expressed racist and antisemitic views, as well as references to white supremacist ideologies. These documents were reviewed by CBS News, a U.S. news partner of the BBC, and pointed to the Christchurch shooter, who killed 51 people at two mosques in New Zealand in 2019, as an inspiration. The case has raised concerns about the influence of extremist ideologies on young people and the role of online content in planning and promoting violence. The indictment of the 17-year-old girl highlights the legal consequences of aiding such attacks, even when the individual does not directly participate in the violence. As the investigation continues, authorities are working to understand the full scope of the attackers’ plans and the potential for further threats in the community.
