After spending more than 20 years behind bars for a crime he says he didn’t commit, as well as challenging the allegations of misconduct that led to his conviction for the past decade, Roger Dean Gillispie is one step closer to taking his case to trial against an Ohio police officer accused of misconduct, based on the U.S. Court of Appeals for the Sixth Circuit’s decision this week.

Gillispie brings a civil rights lawsuit against Matthew Scott Moore, a Miami Township police officer who was responsible for much of the investigation into a series of rapes in August 1988 and for the identification of Gillispie as the likely perpetrator, according to Gillispie’s lawsuit filed in U.S. District Court for the Southern District of Ohio.
