ROANOKE, Va. (AP) -

A federal judge has blocked the scheduled execution of a Virginia inmate in order for his appeals to continue.

An Aug. 15 execution date was set for William Morva after his state appeals were exhausted in April. But inmates are guaranteed federal appeals, so Monday's order was no surprise.

Morva was convicted of the 2006 deaths of hospital security guard Derrick McFarland and Cpl. Eric Sutphin.

Morva was in jail awaiting trial on attempted robbery charges when he was taken to a Blacksburg hospital for treatment of an injury. He overpowered a sheriff's deputy and used his pistol to shoot McFarland. Then he shot Sutphin during a manhunt that closed down Virginia Tech's campus on the first day of classes.
