Possible source of animal hairs in Atlanta child slayings case can be killer's dog

The dog that belonged to a convicted killer cannot be excluded as a possible source of animal hairs on the bodies of some of the victims in the Atlanta child slayings case.

Attorney Jack Martin said in a statement that he had received the formal report of DNA tests conducted on the animal hair by the University of California, Davis.

While the results suggested that Wayne Williams' dog could not be excluded as a possible source of the animal hairs on the bodies, at the same time the tests could not conclude that the hairs came from Williams' dog.

Martin dubbed the results "inconclusive," saying he believes testing of other evidence currently being done by the FBI could be more significant to his client's effort to clear his name after more than 20 years in prison.

District Attorney Paul Howard has refused to comment on the report since receiving it via e-mail on Friday. He has scheduled a news conference for Tuesday to discuss the results. A spokeswoman for Howard said earlier Monday that Howard would have no comment until Tuesday.

In February, a Superior Court judge ordered the testing at the request of lawyers for Williams, who was convicted of killing two people and blamed for 22 other murders in the late 1970s and early 1980s.

The judge ordered that animal hairs found on some of the victims be compared to samples of hairs from Williams' dog.
