The Osage County Sheriff's Office is investigating a fatal accident involving a live mule from Sunday.
Sheriff Laurie Dunn says two people were riding the animals on Kansas Highway 368 near Vassar when the accident happened around 6 pm. A loud bang from a passing car spooked the mule, which bucked and threw its rider.
The woman was pronounced dead at the scene. The other rider and the mules were unhurt. Names have not been released pending notification of family.
The investigation continues.
