DNA collection of suspected East Area Rapist can continue

Zodiac Killer

Zodiac Killer

Police believe the 72-year-old raped at least 45 women, killed a dozen people and burgled as many as 150 homes in an infamous crime spree that spanned from the mid-1970s to 1980s and stumped authorities for more than four decades.

While catching DeAngelo, if he is the "Golden State Killer", is a huge victory for the public and the police, it's worth noting that he never uploaded anything.

"DNA is part of a larger issue of 'How do we profile people in the 21st century?'" Turow said.

Six months after Bates' death, an unsigned letter arrived at the Riverside Daily Enterprise.

DeAngelo's public defenders had sought to block authorities from collecting additional DNA from him, taking his picture and collecting fingerprints as he sits in Sacramento County jail.

"Because it's a partial, the process they used on the Golden State Killer would be much more hard to narrow down to a specific individual", said Michael Butterfield, writer and researcher for ZodiacKillerFacts.com.

"I think Zodiac was definitely licking his own stamps and envelopes", Voight said. We have seen appropriate uses by law enforcement.

Poyser said new developments in DNA extraction technology mean the department will be able to extract DNA markers from several letters and envelopes the Zodiac Killer sent as taunts while he was active.

A partial DNA sample also exists from evidence recovered from the Lake Berryessa murders, said Lt. Chris Carlisle of the Napa Sheriff's Office.

"But with 'probable cause, ' the police actually can carry out wiretaps, plant bugs, monitor our emails, track us as we move around, or even compare our DNA with DNA from crime victims", he said.

There are 900,000 DNA profiles on GEDmatch's site: bit by bit, profile by profile, the site is building an ever-more-accurate roadmap. The Zodiac Killer attacked two college students, Bryan Hartnell and Cecelia Shepard, with a knife there in 1969.

Joseph James DeAngelo, accused of killing 12 people in California between 1976 and 1986, was arrested last week after officials say he was identified through a crime scene DNA link to genealogy websites. The arrest of DeAngelo stunned his community.

Using similar techniques with a DNA sample from the man known as Larry Vanner who died in prison in 2010, investigators discovered the identity of the New Hampshire killer. Detectives and others working a case during the time period when the Zodiac Killer was active didn't use gloves since DNA testing wasn't an actual thing, which led to DNA evidence being contaminated.

Carlisle said his agency was not actively investigating the Zodiac case, but did follow tips as they arise.
