According to researchers online, the 15-year-old female suspect who killed two people and herself at the Abundant Life Christian School in Madison, Wisconsin, earlier this week was associated with Satanic, pedophilic and militant accelerationist groups.

The suspect, Natalie (or Samantha) Rupnow, reportedly published a manifesto that was obtained by Reduxx journalist Anna Slatz via Rupnow's boyfriend.

Slatz also clarified rumors that either Rupnow or the boyfriend were transgender, saying she was a biological female and he's a biological male.

The Reduxx co-founder and author posted an ???? thread on Monday detailing how she came across the alleged manifesto.

"I have made contact with the alleged boyfriend of the Wisconsin shooter," she wrote. "He has very graciously provided me the full manifesto, which I verified by having him screen record himself opening it from a direct link the shooter sent to him via WhatsApp."

The boyfriend also claimed the image of Rupnow being shared online (seen on the left below) was altered to make her look different and provided Slatz with another image he claimed is authentic (on the right below).

The boyfriend was reportedly in contact with Rupnow for two years as part of a long-distance online relationship, but he said they never met in person.

Throughout the manifesto posted by Slatz, the teen suspect described her troubled home life and expressed an infatuation with mass killers from the past.

Rupnow specifically showed interest in European mass murderers, such as Pekka Eric Auvinen, Arda Küçükyetim, and Vladislav Roslyakov.
