A defendant has changed his plea in an Ashland County kidnapping and rape case. 25-year old Brock Martin has now entered a not guilty plea by reason of insanity to aggravated burglary, rape and kidnapping charges. Martin had entered a not guilty plea to the charges just last week. This all comes out of an incident on August 18th when Martin was arrested after he broke into a home, grabbed a six-year old girl from her bed and then raped her in the backyard of the residence. Martin is currently in the Ashland County Jail where bond has been set at $1 million.
