The suspect who is alleged to have shot dead two children and injured 17 others has been named as the female-identifying son of a church employee.
Footage of Westman shared on social media showed a number of offensive messages scribbled onto his magazines, including one which said: “Kill Donald Trump.”
The 23-year-old, whose mother Mary was a parish secretary at Annunciation Catholic Church before retiring in 2021, had “no significant criminal history” before today’s shooting.
In a now-deleted YouTube video, Westman seemingly shared his manifesto, which also included racial slurs, anti-Trump rhetoric and text in Russian.
It also featured a drawing of a church and a man stabbing the drawing repeatedly as he said: “I’m going to kill myself.”
Other clips appeared to show the 23-year-old lauding other mass shooters, with other magazines being emblazoned with the words “for the children” and “where is your God?”
Westman’s manifesto included a photograph of Sandy Hook shooter Adam Lanza, who killed 27 people in 2012.
