First results in

Tarrance's stepson, Dennis Kaufman, gave the FBI letters and envelopes from his stepfather for the DNA tests, convinced they would prove Tarrance is the Zodiac. According to Dennis, the tests on the envelopes came back inconclusive, and the results were odd. Investigators found mixed DNA on the envelopes, as if two people licked the same envelope, rendering it useless...........
---------The inconclusive results explain why the FBI agents in Washington state picked up Tarrance's dentures two weeks ago: to get another DNA source. As far as we know, those tests have not come back yet, but because this is an open investigation, the FBI is not commenting.
