Fugitive wanted in Ohio couple's murder captured in Ariz.

CLEVELAND -- A man wanted in the killings of an elderly Ohio couple and in armed robberies in three states was arrested early Thursday in Arizona after a high-speed chase and nationwide manhunt.

An FBI spokeswoman in Cleveland said 29-year-old Robert Clark was arrested by the Mohave County sheriff's office in Kingman. One of his companions, 26-year-old Tabatha Hazel, a suspect in the armed robberies, was arrested with him. A third companion, 28-year-old Jeffrey Caley Jr., fled and is still being sought by authorities.

Clark has been charged with one count of 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 Jan. 22, the day after they were reported missing from their home.

The Chumneys had four children. Their daughter Diane Enama, who found her parents' home ransacked Jan. 21, declined to comment Thursday.

The FBI had offered a $20,000 reward for information leading to Clark's capture. It wasn't immediately clear Thursday whether anyone could claim the money.

A second suspect in the slayings, 21-year-old Jeffery Stewart, was arrested Saturday. He is charged with one count of murder and is being held on $2 million bond.

Authorities have said Stewart implicated himself and Clark in the killings. Clark, Caley and Hazel are suspected of being involved in the armed robberies of gas stations and convenience stores in West Virginia, South Carolina and Georgia on Saturday and Sunday, and officials had warned they could be on their way to Florida.

No one was hurt in the robberies.

The trio was last seen during a robbery in Donalsonville, Georgia, on Sunday night, said Tom Couts, a Coshocton County sheriff's detective. Surveillance video shows Clark holding a sawed-off shotgun and Caley holding a pistol as a clerk walks in front of them. Hazel went inside the store before Clark and Caley entered, Couts said.

Caley and Hazel were not involved in the Chumney slayings, Couts said.

It appears that Clark and Stewart knew each other through a landscaping service where they had worked, Couts said. Clark was released from prison in May after serving a 4 1/2 -year sentence for robbery and other charges.

Couts said authorities believe the Chumneys were driven to a country road in Coshocton County where they were shot before their car was set on fire.

Authorities received a break in the investigation after surveillance video was released to the public that shows Clark's van at a gas station where Stewart bought a gas can and filled it, Couts said. Stewart called police after seeing the video.

He was arrested on a traffic warrant and provided statements implicating himself and Clark, Couts said.
