Agents carried out another search on Friday of the LaFayette, Ga., home of Sam Parker, whose wife, Theresa, has been missing for over two months.
Officers arrived at the home on Cordell Road Friday morning and stayed for about six hours.
It is the fourth search of the house.
The search comes after the former LaFayette Police sergeant gave an interview to an Atlanta TV station in which he said he believes his wife is still alive.
He told the station he believes she had an affair and took off afterwards.
Family members of the Walker County 911 dispatcher said there "was no affair."
