SIDNEY — The third defendant in the September beating of a 38-year-old woman was sentenced Tuesday in Shelby County Common Pleas Court.

Andrew Mitchell, of Sidney, a 17-year-old juvenile being charged as an adult, was sentenced to seven years in prison for his role in the crime.

Mitchell was originally charged with one count of aggravated robbery, a felony of the first degree, with a firearms specification.

He had originally plead not-guilty in October and then entered a guilty plea in December. The terms of his guilty plea included the state dropping the firearms specification.

His co-defendants, Skylar J. Reynolds, 19, and William Blankenship, 19, both of Sidney, were sentenced in January both to seven years in prison as well.

The crime happened on Sept. 23, 2015 at around 12:30 a.m. A 38-year-old female was walking in the 100 block of North Walnut Avenue, Sidney, when three male subjects wearing hoodies and sock hats approached her. All three were armed with what appeared to be handguns and demanded the victim’s property. The victim attempted to call the police using her cell phone.

“At that time they struck her over the face and head area with either a weapon or a metal object, causing serious fractures to her face, her jaw, her nose and chin. It was a brutal attack,” Sidney Police Chief William Balling said at the time.

Thanks to calls from the public, the tactical response teams from Sidney, Piqua and Shelby County Sheriff’s Office were deployed and executed a search warrant at 233 ½ N. West Ave. in Sidney that same afternoon.

At that time Reynolds and Mitchell were taken into custody. Officers and investigators executed a search warrant at Blankenship’s residence, 827 S. Ohio Ave., but discovered that he had left the residence prior to officers’ arrival.

An arrest warrant was issued out of the Sidney Municipal Court for Blankenship. He turned himself over the sheriff’s office later that day.

Blankenship and Reynolds were charged with the same crime as Mitchell and also entered a guilty plea on the terms of dropping the specification.
