BREAKING: Iowa police confirm 6th grade student killed by 'genderfluid' Dylan Butler during Perry High School shooting, IED found on site

Police have confirmed that the one deceased victim of Dylan Butler's shooting rampage at Perry High School was a sixth-grade student, and that an improvised explosive device was found on site.

Police said that the 6th grade student was at the high school because he was participating in a breakfast program prior to the start of the school day that is located at the high school.

The 17-year-old student killed one and injured five early Thursday morning before turning the gun on himself. None of the victims' names have been publicly released. Police said that there was no indication that the shooting had anything to do with race.

During a press conference, police confirmed that Butler had murdered a sixth-grade student. Four of those injured were students, while the fifth was a school administrator.

The surviving victims are currently being treated at area hospitals.

"The shooter has been identified as 17-year-old Dylan Butler," police said, noting that he was "a student at Perry High School."

Butler was found to have been carrying a "pump-action shotgun and a small calibre handgun" at the time, and also "made a number of social media posts in and around the time of the shooting."

"All evidence thus far suggests that Butler acted alone," police added.

"Officers located, during a search of the school, an improvised explosive device," police said, noting that authorities were able to "render the device safe."

This is a breaking story and will be updated.
