Just read a headline that says the Zodiac's DNA has been sent to genealogy sites looking for a possible match, results will be back in a few weeks........its from Sac Bee online paper but I've used all my free look ups for the month, so I can't link the actual story, if some can copy the link & paste it on here, much appreciated.

From the link:
Vallejo police Detective Terry Poyser, who has worked the Zodiac case for four years, said his agency has submitted two envelopes that contained letters from the Zodiac Killer for a type of advanced DNA analysis that previously had not been available in the case.
Poyser declined to identify the lab, but said it would attempt to obtain a full DNA profile from saliva on the envelope flap and stamps. He said he expected to have results back from the lab as soon as in the next few weeks, and almost certainly by summer.
"They were confident they would be able to get something off it," Poyser said.

The department has three letters and two envelopes from the Zodiac, Poyser said. The envelopes each have a double stamp, which Poyser said was a trademark of the Zodiac. They originally were sent to the San Francisco Chronicle and the San Francisco Examiner, he said. The third letter was sent to the Vallejo Times-Herald, but does not have an envelope with it, he said.
San Francisco police, who have been working on the case collaboratively with Vallejo, also have cards and ciphers sent by the Zodiac, he said.
Poyser said he believes the Zodiac Killer is no longer alive. Arthur Leigh Allen, a former elementary school teacher and convicted child molester who lived in Vallejo, long was considered a top suspect. Allen died in 1992 at the age of 58, according to media reports.
