Officials with the Sioux Falls Police Department say a fatal crash involving a school bus and a pedestrian took place at 7:35 a.m. Wednesday on 12^th St and Garfield Avenue.

Authorities say the school bus was traveling on West 12the Street and took a left onto Garfield Avenue to go south, when a 50-year-old man crossing the street, was struck by the bus. Emergency personnel were called in almost immediately and reported to have administered CPR to the man, a press release from the department stated.

However, the man was pronounced dead on the scene.

Department spokesperson Sam Clemens said there were children present on the bus but they were eventually taken off and put on another one. Authorities are not yet sure how much or which part of the crash was witnessed by them.

Police do not have exact information on where the bus was traveling. Clemens said no other vehicles were involved in the incident.

The intersection on 12th St was closed for the first couple hours afterward, impacting the entire area around Kiwanis Avenue and Western Avenue. The roads have since been reopened.

The Sioux Falls School District has protocols for emergency situations like these which impact students where the Crisis Team of school counselors stepped in within the hour to support students, says Community Relations Coordinator DeeAnn Konrad.

"We never know how children will respond and we never know what previous experiences they may have had that will impact their response," Konrad said. "Our job may be to educate children every day in the classroom, but school staff do so much more. They care about the emotional well-being of our students."

Police will do a mapping of the whole scene and will plot that on a scaled map to help with the investigation, Clemens said. Drones available to the department would be one of the tools used to get high-end aerial pictures and scaled, detailed mapping of the scene, Clemens says.

Clemens said quite a few witnesses had called in the crash. They will be playing a part in understanding what exactly happened, he said. The position of the pedestrian and whether he was crossing with the light or against the light is an important question. While police may have an idea, Clemens says witness versions of the story might differ, and hence, no definitive answer has been determined yet.

This is an ongoing investigation. The department will keep the public updated through their social media accounts with developing information.
