Cops: Ohio double murder suspect could be heading to Fla.

A fugitive suspected of abducting and killing of an elderly couple in Ohio last month and then embarking on a multi-state armed robbery spree could be heading to Jacksonville, reports CBS affiliate WJAX.

Robert Clark, 29, is a suspect in the slayings of Doyle Chumney, 88, and his 79-year-old wife, Lillian. They were reported missing Jan. 21 from their home in Strasburg, Ohio, south of Canton , after they failed to pick up their son to give him a ride to an airport. The couple's remains were found the next day in the front-passenger compartment of their badly burned car on a country road in Coschocton County.

Authorities say there was evidence of a struggle inside the Chumneys' home.

Clark, 29, along with a man and a woman from the Canton area, are believed to be involved in two armed robberies in West Virginia on Saturday, one in South Carolina on Sunday afternoon and one in Georgia on Sunday night, said Tuscarawas County Chief Deputy Orvis Campbell. All the robberies occurred at gas stations or convenience stores.

Now, police say the trio may be driving a green minivan with an Ohio license plate, and heading to the Jacksonville area, reports WJAX. Police are considering them armed and dangerous.

A second suspect in the slayings, Jeffery Stewart, 21, was arrested in Ohio Saturday and charged with murder. Authorities have said Stewart made incriminating statements and implicated Clark in the abductions and killings.

An Ohio judge set a $2 million bond for Stewart.
