(KAIR)--An early Sunday evening motorcycle crash, in Atchison County, sent the Horton rider to the hospital.

According to a release from Atchison County Sheriff Jack Laurie, deputies responded to the scene of the crash, K9 Highway at Highway 159, north of Muscotah, following the 5:00 crash. However, the rider, identified as 26-year-old Nathan Pillman, had, according to Laurie, " been taken to Amberwell [Hospital in Hiawatha] prior to [the Sheriff's Office] being notified of the crash." The motorcycle, Laurie says, "remained on the scene" when deputies arrived.

Pillman, after being taken to the hospital, was being treated for what Laurie calls "unknown injuries."

According to Sheriff's Office investigators, Pillman's motorcycle crashed when he was unable to negotiate a curve.

The investigation into the crash is continuing.
