• A 17-year-old girl from North Carolina indicted for murder in connection to a mosque shooting in San Diego.
• The girl allegedly livestreamed the attack and disseminated shooters' white supremacist manifesto.
• Authorities believe she may have been radicalized in the same extremist networks as the shooters.
• The shooting occurred on May 18, resulting in three fatalities, including a security guard.
• Charges include three counts of murder and conspiracy, as she can be tried as an adult.

A 17-year-old girl from North Carolina has been indicted on three counts of murder in the aftermath of a mass shooting at the Islamic Center of San Diego. Prosecutors allege that she aided and abetted the crime by livestreaming the attack and sharing the shooters' racist manifesto online, according to CBS News and Los Angeles Times.

The girl, who remains unnamed but is identified as a high school student from Winston-Salem, is also facing a charge for conspiracy in connection with the shootings that took place on May 18. The attack resulted in the deaths of three people, including security guard Amin Abdullah, and was perpetrated by two teen gunmen, Cain Clark and Caleb Vazquez, according to BBC and CBS News.

Authorities have indicated that the girl had prior knowledge of a broader plan that involved further attacks on a local Jewish temple and predominantly Black high school. However, these subsequent shootings did not occur, as the gunmen took their own lives after the attack at the mosque, according to Los Angeles Times and BBC.

Forsyth County District Attorney Jim O'Neill emphasized the severity of her actions, noting that she could be held criminally responsible in the same way as the shooters due to North Carolina's laws. He remarked on the need for parents to monitor their children's online interactions, highlighting how radicalization can occur in isolated online communities, according to Los Angeles Times and CBS News.

The attack involved significant premeditation, with both shooters reportedly stockpiling a weapon cache that included around 30 firearms. They filmed their actions using GoPro cameras attached to their helmets, as they intended the violence to be "memorialized" for others to see, according to BBC.
