Staff, wire report COLUMBUS — The Ohio Supreme Court on Thursday delayed the execution of a convicted Trumbull County killer whose case federal public defenders said slipped through the cracks of the legal system. Death row inmate David Martin of Warren, 36, had been scheduled to die May 26. Martin went without a lawyer for more than a year after the Ohio high court upheld his sentence in 2018 and missed a chance to make a customary appeal to the federal courts. Justices announced this week they have stayed Martin’s execution until all his legal options are exhausted. Martin was sentenced to die after he was found guilty by jury on charges of aggravated murder, aggravated robbery and kidnapping on Sept. 11, 2014.
