Florida set to execute convicted killer Oba Chandler

(CBS/AP) STARKE, Fla. - The man convicted of killing an Ohio woman and her teen daughters after talking them into going his boat while they were on vacation is scheduled to be executed by lethal injection Tuesday at the Florida State Prison.

Oba Chandler, 65, was convicted in the 1994 deaths of Joan Rogers, 36, and her daughters Christie and Michelle, 14 and 17. Authorities believe the family met Chandler when they asked him for direction to their motel. Chandler sweet-talked them into going on his boat on June 1, said police.

Once on the boat, police said Chandler bound the womens' arms and legs, tied concrete blocks to ropes around their necks, then threw them overboard. The three were found floating in Tampa Bay a few days later, naked from the waist down.

It took three years to make the case, which was eventually cracked because authorities found a tourist brochure with Chandler's handwriting on it in Rogers' car, and Chandler resembled a composite sketch of a suspect wanted in an unsolved assault of a Canadian woman aboard a boat in Tampa Bay.

Authorities put the handwriting on a billboard to see if anyone recognized it. It worked: one of Chandler's neighbors recognized it and called police.

Gov. Rick Scott signed Chandler's death warrant on Oct. 11. The Florida Supreme Court has affirmed a lower court decision to go ahead with the lethal injection.
