Video: Official Provides Update on Deadly Iowa School Shooting

My name is Mitch Mortvedt. I’m an assistant director with the Iowa Division of Criminal Investigation. At 7:37 a.m. — excuse me, on Jan. 4, 2024. As additional officers responded, a systematic approach, search, of the school took place. Officers located during the search of the school, an improvised explosive device. The state fire marshal and the Bureau of Alcohol, Tobacco and Firearms rendered the device safe. Numerous officers from multiple agencies were able to secure the school and verify no additional threats. At the same time, first responders were rendering aid to the victims who were later transported to area hospitals. The shooter has been identified as 17-year-old Dylan Butler, a student at Perry High School. Butler was armed with a pump-action shotgun and a small-caliber handgun. Butler also made a number of social media posts in and around the time of the shooting. Law enforcement is working to secure those pieces of evidence. All evidence thus far suggests that Butler acted alone. The Iowa Division of Criminal Investigation is serving as the lead investigative agency with assistance from the Perry Police Department, the Dallas County Sheriff’s Office, the F.B.I., the A.T.F. and the Dallas County Attorney’s Office.
