Minneapolis shooter Robin Westman, 23, killed two children and injured 17 at Annunciation Catholic School.
His weapons had messages like “Kill Donald Trump,” “Nuke India,” and “Burn Israel.”
A video showed him with his rifle, shotgun, and pistol, along with magazines marked with hateful notes and references to past shooters.
Westman, who died by an apparent self-inflicted gunshot, had legally changed his name from Robert to Robin in 2020 and posted disturbing videos online before the attack.
Despite having a clean record and operating solo, the incident shocked the nation. President Trump ordered all US flags to be flown at half-staff to honor the solemn occasion.
