Columbia County authorities hope the offer of a $15,000 reward will stimulate some action in a 6-month-old murder case that has investigators at a dead end.
The family of slain Evans couple Frederick and Yong-Suk Walker put up the money Friday for the reward for information that will lead to the arrest and conviction of their killers.
"We have investigated numerous leads resulting in the development of significant information," said sheriff's Capt. Steve Morris. "However, this investigation has not yielded an arrest or the person responsible for this crime."
Investigators hope the reward will generate some new leads and an eventual arrest, he said.
"This type of investigation requires hard work, commitment, patience and luck," Capt. Morris said. "In an effort to solve this crime we have sought to have an award offered which will lead to the conviction of the murderer."
Deputies were called to the Walkers' home in the upscale Country Place subdivision on the afternoon of Feb. 3, after a family member's phone calls to the residence went unanswered.
Inside, an officer discovered the bodies of Mr. Walker, 58, and his wife, 53, in an upstairs bedroom, still dressed in their bedclothes. Both had been shot to death, and the house appeared to have been ransacked.
After the tragedy, the lives of the Walker children Vivian and twin brothers, Donald and David changed.
Vivian and Donald dropped out of Georgia State University to assist brother David in attending to their parents' affairs, and the three have settled into operating the family's Kissingbower Road Package Shop.
"I don't want this to be one of those things goes on for years and nothing ever happens," said David Walker, who police questioned for two days after the killings and whose home and business were searched before he was released.
Investigators no longer consider David Walker a suspect in the case, Capt. Morris said.
Although at first bitter about his treatment by authorities, the younger Mr. Walker said he is now past those feelings.
"I guess they made a mistake and that's it," he said.
He and his siblings just want their ordeal to be over and hope the reward will bring it to an end.
"I wouldn't imagine anyone not being frustrated," Mr. Walker said. "The (reward's) purpose is to find the person who did it. That's all we want."
