(Perry, IA) — The student who opened fire in an Iowa high school is believed to have posted an ominous TikTok video. A TikTok video that is said to be from the shooter’s account shows the 17-year-old inside a school bathroom with a duffel bag. It’s captioned “now we wait.” The sound attached to the post is called “Stray Bullet” by the German band KMFDM. An Iowa Public Safety official said the 17-year-old, who killed a sixth grader in the Perry High School shooting and himself, made several social media posts around the time of the shooting. He added that law enforcement is gathering that evidence.
