California police working on DNA match for Zodiac Killer
SAN FRANCISCO (AP) — Detectives in Northern California are trying to get a DNA profile on the Zodiac Killer to track him down using the same family-tree tracing technology investigators used in the Golden State Killer case.
Vallejo police Detective Terry Poyser tells the Sacramento Bee his agency has submitted two envelopes that contained letters from the Zodiac Killer for DNA analysis.
Poyser says the department is working with a private lab to try to obtain a full DNA profile from saliva on the envelopes’ flaps and stamps. Results are expected in the next few weeks.
The Zodiac Killer stabbed or shot to death five people in Northern California in 1968 and 1969. He was dubbed the Zodiac Killer after he sent taunting letters and cryptograms to police and newspapers that included astrological symbols.
