Updated at 12:45 p.m. ETWilliam Morva is scheduled to die by lethal injection at 9 p.m. ET Thursday in Jarratt, Va., as a chorus of voices at home and abroad call for the execution to be halted amid questions regarding his mental stability.Morva, 35, was convicted of killing two men in 2006 and sentenced to die two years later. His attorneys are asking Virginia Gov. Terry McAuliffe to commute the sentence to life in prison.But just hours before Morva was set to die Thursday, McAuliffe said he still has not decided which way he will go."It's the hardest part about being a governor is to deal with these life and death decisions," McAuliffe said at a Charlottesville news conference. "I didn't sleep a wink last night."By midday, he said he still had some unanswered questions. "I will make a decision after those questions are answered."Morva was in jail in August 2006, awaiting trial on attempted robbery charges, when he was taken to the hospital for treatment of a minor injury. He escaped, stealing a sheriff deputy's gun. Then he shot Derrick McFarland, a hospital security guard, and, a day later, Eric Sutphin, a sheriff's deputy, killing both men.Morva's attorneys do not dispute that Morva pulled the trigger but say he was suffering from delusions at the time."In William's mind, he was dying in that jail, and he only took the steps that he believed were necessary in order to save his own life," Morva's lawyer Dawn Davison told Sandy Hausman from member station WVTF.At the time, Morva was convinced he had a serious intestinal disorder, according to Davison."When he was free, he would eat raw meat or nearly raw meat in large quantities, large quantities of cheese, at times trying a diet that consisted of nuts and berries and pine cones," Davison told Hausman.Morva's attorneys say the jurors who sentenced Morva to die in 2008 did not know how serious his mental illness is.As The Associated Press reports:
