SIDNEY — A motorcyclist was killed Sunday morning in a one-vehicle crash.

According to the Shelby County Sheriff’s Office, Justin Lee Withrow, 32, was killed in the crash.

Deputies responded to a motorcycle crash with injury at 12:38 a.m. Sunday, June 18, at 4822 Tawawa Maplewood Road.

Preliminary investigation shows Withrow was driving a 2000 Harley Davidson motorcycle and was traveling northbound in the 4000 block of Tawara Maplewood Road. Withrow failed to negotiate a left-hand curve, and the motorcycle traveled off the right side of the road. The motorcycle then went into the driveway at 4822 Tawawa Maplewood Road, where it traveled down the driveway and struck a parked trailer. Withrow was ejected from the motorcycle and pronounced dead at the scene.

Speed and alcohol are believed to be factors in the crash, reports the Sheriff’s Office.

Along with the Shelby Sheriff’s Office, Perry Port Salem Rescue Squad, Riverside Rescue Squad, Rosewood Fire Department and Shelby County Coroner’s Office assisted at the scene.

Withrow’s residence was not available at press time. It’s not known if he was wearing a helmet at the time of the crash.

The crash remains under investigation.
