The DNA tests determined that a hair found in the left hand of MacDonald's wife matched the DNA of her husband, not an outsider, but three other hairs found in the apartment did not belong to any member of the family.
However, the three other hairs did not match the DNA of the people MacDonald's defense team claims committed the crime -- Helena Stoeckley and her boyfriend, Gregory Mitchell. MacDonald has long claimed that hippies, including a woman wearing a wig and a big hat, were responsible for the death of his family.
MacDonald's defense attorney, Tim Junkin, said the results showing a hair found under the fingernails of one of MacDonald's daughters was "profound" new evidence. "It's a powerful piece of evidence," Junkin said.
The 1970 murders of Colette MacDonald, 26, and her daughters Kimberley, 5, and Kristen, 2, were dramatized in the best seller and miniseries "Fatal Vision." Another book, " Fatal Justice" claimed MacDonald was innocent.
MacDonald has been serving three life sentences in federal prison.
