A month after a student opened fire at Abundant Life Christian School, another killed a classmate at Antioch High School. Both were active in an internet subculture that glorifies mass shooters and encourages young people to commit attacks. Moments before 15-year-old Natalie Rupnow opened fire inside her Madison, Wisconsin, school, killing two people and herself last month, a social media account believed to be hers posted a photograph on X showing someone sitting in a bathroom stall and flashing a hand gesture that has become a symbol for white supremacy. As news about the shooting broke, another X user responded: “Livestream it.” Extremism researchers now believe that second account belonged to 17-year-old Solomon Henderson, who police say walked into his high school cafeteria in Nashville, Tennessee, on Wednesday and fired 10 shots, killing one classmate and then himself. Archives of another X account linked to him show that he posted a similar photo to Rupnow’s in his final moments. While there isn’t any evidence that Rupnow and Henderson plotted their attacks together, extremism researchers who have tracked their social media activity told Wisconsin Watch and ProPublica that the two teenagers were active in the same online networks that glorify mass shooters, even crossing paths. Across various social media platforms, the networks trade hateful memes alongside terrorist literature, exchange tips on how to effectively commit attacks and encourage one another to carry out their own. The researchers had been tracking these networks for months as part of work looking into growing online extremist networks that have proliferated across gaming, chatting and social media platforms and that they believe are radicalizing young people to commit mass shootings and other violence (…) The extremism researchers linked accounts to Rupnow, who went by Samantha, by tracing her activity across multiple social media profiles that revealed common biographical details, including personal acquaintances and that she lived in Wisconsin. On the bathroom post, one person the account regularly interacted with referred to Rupnow by her nickname, “Sam.” Wisconsin Watch and ProPublica were able to verify the social media posts and the connections between the accounts by retracing the researchers’ steps through archived social media accounts and screenshots. On Thursday, ABC News cited law enforcement sources in reporting that a social media account connected to Henderson may have been in contact with Rupnow’s social media account. The information reviewed by Wisconsin Watch and ProPublica details their suspected connections and interactions. Nearly all of the accounts that researchers have linked to Rupnow and Henderson have now been suspended.
