Suspect nabbed after nationwide manhunt pleads not guilty in slayings of elderly Ohio couple

A man who led authorities on a nationwide manhunt after being charged in the slayings of an elderly Ohio couple has pleaded not guilty to aggravated murder and other charges.

Twenty-nine-year-old Robert Clark entered the plea Friday in Coshocton, about 75 miles northeast of Columbus.

Clark could receive the death penalty if convicted. His co-defendant pleaded not guilty this week and doesn't face capital punishment.

They are accused of killing 88-year-old Doyle Chumney and his 79-year-old wife, Lillian. The Strasburg couple's bodies were found inside their torched car Jan. 22, the day after they were reported missing. Authorities say they believe the Chumneys were shot by Clark before the car was set on fire.

Clark and two companions were arrested Feb. 5 in Arizona after armed robberies in three states.
