by Holly showing him holding the revolver to his head. The shooter was identified as 16-year-old Desmond Holly, a student at the school. After investigating Holly's phone, investigators reported that Holly had been exposed to extremist online material and appeared to have adopted neo-Nazi ideology in the months before the attack, being radicalized by an "extremist network". Officials also indicated that he may have expressed interest in previous school shootings, though the precise motive remains under investigation. Investigators found that Holly had several TikTok accounts, filled with white supremacist symbols. According to the Anti-Defamation League's Center on Extremism, he was active on the app's "True Crime Community", where participating users have a fascination of mass murderers and serial killers. His profile picture on the app was an edited image of Elliot Rodger, perpetrator of the 2014 Isla Vista killings. A few days before the shooting, Holly posted a picture on the app in a pose similar to the perpetrator of the 2024 Abundant Life Christian School shooting with a shirt he made that was worn by Dylan Klebold during the 1999 Columbine High School massacre, ==Aftermath==

Jefferson County Public Schools closed Evergreen High School in the days following the shooting. When classes resumed, the district assigned a full-time school resource officer to the campus and increased on-site security personnel. Hundreds of residents attended a community vigil the day after the shooting, and a temporary support center was established for students, parents, and staff. In the weeks that followed, officials also investigated several possible threats reported on social media, which they later determined were either unfounded or posts by students processing the trauma of the shooting. ==See also==
