Moments before a 17-year-old unleashed gunfire at Iowa’s Perry High School, killing a sixth grader and wounding five other people, the student is believed to have posted a foreboding TikTok video. On the morning shooter Dylan Butler opened fire, a TikTok post believed to be from the shooter shows him inside a school bathroom posing with a blue duffel bag, captioned: “Now we wait.” The song “Stray Bullet,” by the German band KMFDM, accompanies the post – which has been removed from the platform. The band’s lyrics have also been cited by the student gunmen who carried out the 1999 massacre at Columbine High School in Colorado, where 13 victims were killed, CNN has reported. The gunman in Iowa “made a number of social media posts in and around the time of the shooting” on Thursday morning, said Mitch Mortvedt, assistant director of the Iowa Department of Public Safety Division of Criminal Investigation. “Law enforcement are working to secure those pieces of evidence,” he added. (…) Still, investigators are trying to determine why Butler entered the school with a pump-action shotgun and small-caliber handgun, Mortvedt said. Officers also discovered a rudimentary explosive device after the killer went on the deadly rampage before classes started on the first day back to school since winter break.
