WINONA, Minn. (AP) — Police say a woman on a bike was struck and killed by a school bus in Winona Monday.

Deputy Police Chief Tom Williams says the crash happened about 8:30 a.m. at an intersection near Winona Senior High School. Williams says the Minnesota City Bus Company school bus, driven by a 55-year-old man, was attempting a left turn when it struck the bike and the 74-year-old woman. She was pronounced dead at the scene.

Williams said the Minnesota State Patrol is investigating the crash because it involved a commercial school bus.

Superintendent of Schools Scott Hannon tells KAGE radio there were two students on the bus at the time of the crash. Neither student was injured.
