COLUMBUS, Ohio (AP) — A federal judge in Ohio will once again weigh competing testimony from expert witnesses sparring over the effects of a lethal injection method. An anesthesiologist hired by lawyers for condemned inmate Dennis McGuire says the state's untried two-drug process will subject him to agony and terror as he tries to catch his breath. "McGuire will experience the agony and terror of air hunger as he struggles to breathe for five minutes after defendants intravenously inject him with the execution drugs," the inmate's attorneys said in a Monday court filing. The drug method has been part of Ohio's execution process since 2009 — though never used — and higher courts have twice rejected claims that the drugs pose a risk of severe pain, the state argued in opposing McGuire's attempt to stop his execution.
