CLEVELAND – The Associated Press is reporting that a man wanted in the killings of an elderly Ohio couple and in armed robberies in three states has been arrested in Arizona.

These are the same suspects also named by the FBI in the robbery of a Donalsonville gas station.

An FBI spokeswoman in Cleveland says Robert Clark, 29, was arrested Thursday by the Mohave County sheriff’s office in Kingman after a high-speed chase. Arrested with him was Tabatha Hazel, who is a suspect in the armed robberies but not in the killings.

A third companion fled and is still being sought by authorities.

Clark has been charged with murder in the deaths of 88-year-old Doyle Chumney and his 79-year-old wife, Lillian. Their remains were found inside their torched car on a country road January 22, the day after they were reported missing from their home.
