Northern California detectives still trying to identify the infamous Zodiac Killer who targeted victims in the late 1960s and taunted investigators with letters say they hope to try the same DNA tracing technology recently used to arrest a suspect in another string of cold-case serial slayings – those blamed on the Golden State Killer.
But first they have to get a better DNA profile.
Several months ago, the Vallejo Police Department sent two letters written by the Zodiac Killer to a private lab in hopes of finding his DNA on the back of the stamps or envelope flaps he may have licked. They are expecting results soon.
“They were confident they would be able to get something off it,” Vallejo police Detective Terry Poyser told the Sacramento Bee.
