The Iowa State Patrol continues to investigate a single-vehicle accident that injured a woman in Butler County on Sunday (Oct. 15, 2017).

Brandy Hayner, 28, of Shell Rock, was airlifted to University of Iowa Hospitals and Clinics in Iowa City for treatment following the crash, which occurred around noon on County Road C-13 about a half-mile east of Greene.

According to an accident report, Hayner lost control of her vehicle and entered a ditch. The vehicle overturned several times before coming to rest in a cornfield. A preliminary investigation revealed that Hayner was driving very erratically before the mishap occured, the Iowa State Patrol said.

In a Facebook post, Floyd County sheriff's officials said they were called to bring their drone to the crash site to aid in the search for a person who fled the scene. Information in the post said authorities eventually found the subject at a nearby residence after a search that lasted more than two hours.
