BEACON TRANSCRIPT – A former California homicide detective recently declared that it might be possible to establish the identity of the infamous Zodiac killer by taking advantage of cutting-edge DNA sampling techniques. The ex-detective, who now runs Contra Costa Sheriff’s Office’ forensic lab, stated that the result of the recently-performed analysis should be made public in a couple of weeks.
Zodiac Killed Could Be IDed Using Genealogy Website Genetic Material
Pam Hofsass, the head of Contra Costa County’s forensic labs, said that the Zodiac killer case that has puzzled authorities for the past five decades might finally be crack, thanks to the latest discoveries in terms of DNA sampling.
Using a DNA sample harvested from a personal item which belonged to the infamous character who terrorized California during the late ‘60s, the authorities hope to discover his identity.
As Hofsass pointed out, the main difficulty in obtaining a positive result is that the sample might be contaminated. During the late ‘60s, crime scene investigation protocols were somewhat loose, with most of the evidence being handled without gloves or other instruments that prevent contamination.
The former homicide detective, who was assigned the Zodiac Killer case in 2009, said that the collected DNA sample comes from a blood-covered glove supposedly used by the assailant during the murder of Paul Stine in 1969.
Meanwhile, Tom Voigt, an expert on Zodiac’s murder spree, declared that the authorities could potentially obtain a cleaner DNA sample from the envelopes sent by the killer. A saliva sample taken from such an envelope could provide more insight on the case than trying to ‘decontaminate’ another sample.
Hofsass declared that the results of the DNA analysis would be made public in a couple of weeks. Encouraged by the recent arrest of the Golden State Killer, Hofsass believes that this method could work in the Zodiac Killer case.
