“Not only that, but any and all angles that could lead to maybe answering part of why or all of why, the motive,” Mortvedt added. “From bullying to health to friends, family, and school. If you think of it, we're investigating.”
It is not always feasible to ascertain a motive in murder-suicide investigations, Mortvedt said. What Mortvedt meant was that they want to "get to the bottom of" the matter.
Mortvedt stated in a Friday press release that the probe will examine witness reports and interviews. Detectives collected "large volumes" of digital and social media data. The "volumes and volumes" of material to be evaluated include surveillance and body camera video, he said Monday.
Mortvedt claimed Butler made "number of social media posts in and around time of the shooting." His TikTok snapshot before the shooting showed him in a restroom stall with a blue duffel bag by his feet. The caption said "now we wait."
Ron Humphrey, an Iowa State Fire Marshal's Office special agent, said the FBI assisted disassemble Butler's suspected improvised explosive device.
Iowa Gov. Kim Reynolds extended her last week's directive that all flags on state grounds be flown at half-staff until sunset Thursday in honor of Ahmir, whose burial will be place at 10:30 a.m. at St. Patrick Catholic Church in Perry.
The Uvalde Foundation for Kids announced Monday it will change its plans to honor Marburger and Perry Middle School Associate Principal Adam Jessen "for their heroic efforts to save students" during the shootings.
The Dallas-based "national nonviolence advocacy" charity was created following the 2022 Uvalde, Texas, elementary school massacre that killed 19 pupils and two teachers. In a news statement, it stated it had sent "numerous email requests" to Perry Mayor Dirk Cavanaugh and school officials about the prizes.
