A cold case investigator is claiming that the FBI has identified the man suspected to be the infamous ‘Zodiac Killer’ and believes the authorities didn’t look into him enough when he was alive.

Journalist Thomas Colbert says that an FBI whistleblower confirmed to him that Air Force veteran Gary Francis Poste, who has been previously posited as the killer, is currently listed as a suspect.

He claims that FBI labs have a ‘partial’ DNA sample on Poste that links him to the murders. Poste has been dead since 2018.  

‘The felon has been secretly listed as the Zodiac ‘suspect’ in Headquarters’ computers since 2016,’ Colbert’s organization, Case Breakers, said in a statement.

The FBI has been denying that the long-open case has been solved, confirming it was open as recently as October 2021. 

That same month, Poste was identified by Case Breakers as their leading suspect in at least five murders that took place in the Bay Area in 1968 and 1969.

On Wednesday, the organization announced they think they have evidence tying Poste to all of the murders, including a sixth victim from 1966 whom the FBI has denied was connected to the Zodiac Killer.

Case Breakers believes that the federal law enforcement has ignored evidence and state laws in their mishandling of the case. 

‘Like cops, federal agents are dealing with huge caseloads, constant training, odd rules and bureaucracy,’ their FBI whistleblower says. 

‘But when someone wearing a badge or uniform works with others to avoid or hide materials, sidestep difficult procedures, or lie about evidence, they’re hurting our volunteers and the thousands of families waiting for answers,’ 

In a statement, the FBI’s San Francisco Office told Fox News that the case remained ‘open and unsolved’ but provided no further comment, citing ‘respect for the victims and their families.’ 

Case Breakers is demanding a review into both local and federal law enforcement’s handling of the case, also referencing the victims and their families. 

‘As a nation, we’ve abandoned them – especially the remaining 10 brothers and sisters,’ Colbert said.

He called it a ‘coverup’ that was ‘nonsensical for the people that are still waiting.’

In 2021, The Case Breakers had identified Poste, who died in 2018, as the alleged serial killer who was responsible for multiple murders in Northern California in the late 1960’s.

The group – which is compiled of about 40 independent sleuths – announced that Poste had given away weapons and bullets before his death, which could finally lead to the true identity of the killer.

‘When The Case Breakers approached officials about a new Zodiac suspect last spring, five police and state agencies would not cooperate,’ the group said in a statement on Saturday. 

‘But last week, the man who runs the 10-year cold case team, Thomas J. Colbert, received a tip from his long-time sources in the remote town of deceased Gary Francis Poste: They had verified the existence of an evidentiary goldmine.’

The statement revealed that Poste had given away his weapons and bullets, with most of them still remaining untouched and hidden away.

‘Old associates of the housepainter/alleged serial killer claim that, a few years prior to Poste’s 2018 death at 80, he had quietly given away his weapons, pistol parts, gunpowder, bullets and shell casings – more than a thousand, involving 25 different calibers – to his favorite locals,’ they added. 

‘And most of these peculiar ‘gifts’ have remained in basements and closets, untouched, ever since.’

Thomas Colbert, one of the group’s members, boxed up the haul and sent it to team members to have the items investigated in labs in three different states. 

Colbert strongly believes they have nailed the identification of the Zodiac killer more than five decades later.

‘My FBI guys say it’s irrefutable. It’s a match,’ Colbert told Fox News back in 2021.

‘We also have six people that he’s confessed to that he was the Zodiac. Three of them on our court affidavits. So we strongly feel that.

‘And then of course the murder scenes in Riverside, we have counted six similarities at the murder scene.’ 

The team of investigators had also used photographic evidence to compare a distinctive scar seen on the Zodiac Killer and compared it to photos of Poste. 

They have even requested the FBI to test their findings for DNA.

The Case Breakers have also relied on accounts of people who knew Poste, including a neighbor whom the alleged serial and his wife used to babysit as a child, a man who claimed to have been a part of Poste’s criminal ‘posse’ that roamed the High Sierra region, and an ex-girlfriend of Poste’s son. 

Five people were fatally stabbed or shot to death in Northern California in 1968 and 1969, and their killer sent taunting letters and cryptograms to the police and newspapers.

The killer was dubbed ‘Zodiac’ because some of his cryptograms included astrological symbols and references.

The series of unsolved murders inspired many books, documentaries and movies.

According to information released by the Case Breakers, the Zodiac killer was also responsible for the brutal killing of co-ed Cheri Jo Bates, 18, who was found stabbed 42 times and nearly decapitated on October 31, 1966, in Riverside, more than 400 miles south of San Francisco and two years before the Zodiac’s first known killing.

Members of the investigative group claimed that around the time of Bates’ murder, Poste, an Air Force veteran, was getting a check-up at a hospital located just 15 minutes away from the crime scene.

A wristwatch splattered with paint and believed to have been worn by the killer was found near Bates’ body. Case Breakers noted that Poste spent 40 years working as a house painter. 

Additionally, a heelprint found in the dirt at the scene of the stabbing was said to have been been from a ‘military-style boot’ consistent with the style and size of footprints found at three known Zodiac crime scene, and also of Poste.

A year after Bates’ murder, the Riverside Police Department received an anonymous letter, whose author appeared to confess to murdering Bates for turning down his romantic advances. 

In 1975, an FBI memo sent to the Riverside Police Department linked the Bates murder to the Zodiac killings, describing the 18-year-old woman as the elusive murderer’s sixth victim.   

In 2021, Officer Ryan Railsback, the spokesperson for the Riverside Police Department, told DailyMail.com that their homicide unit, working with FBI genealogists, has ruled out any links between the Bates murder and the Zodiac killer, or anyone being potentially identified as the Zodiac killer. 

Railsback said the FBI memo tying Bates’ slaying to the Zodiac killing was based on the confession letter, which in 2016 was revealed to be a fake. 

That year, someone sent an unsigned, typed-up note to the police, revealing that they had sent the bogus confession, which was in fact a cry for attention from ‘a troubled youth.’ 

Railsback stressed that the Bates case remains open, and there is still an active $50,000 reward being offered for information leading to an arrest. 

The police spokesperson noted that last month, an entertainment lawyer with alleged ties to the Case Breakers reached out to the department, saying that his client had information about the Bates case, and asking if the tipster would be eligible to receive the reward money, even if the alleged killer was already dead. 

Railsback said he expressed interest in the information but never heard back from the attorney. 

‘If we really had information that the Zodiac killer was related to Cheri Jo Bates, we would not hide that,’ he stressed. ‘We’re not going to hide information, especially 55 years later.’    

In 2020, a ciphered letter mailed to a San Francisco newspaper by the Zodiac killer in 1969 was cracked by a team of amateur code-breakers from the United States, Australia and Belgium.

According to code-breaking expert David Oranchak, the cipher’s text includes: ‘I hope you are having lots of fun in trying to catch me. … I am not afraid of the gas chamber because it will send me to paradise all the sooner because I now have enough slaves to work for me.’ 

Little is known about Poste’s life beyond the fact that he was married, had a son, and worked as a house painter after retiring from the US Air Force, according to information gathered by the Case Breakers. 

In February 2016, The Union-Democrat reported that 78-year-old Gary Francis Poste, from Groveland, was arrested at his home on Merrell Road on suspicion of inflicting corporal injury on a spouse.

A California woman who lived next door to Poste and his wife, and who had been babysat by the couple as a child in the 1970s and 80s, told Fox News she now believes her neighbor was the Zodiac killer. 

The woman, who gave her name only as Gwen, Poste taught her how to shoot, sometimes going into the woods for target practice five days a week.

‘In the last year of her childcare, [Gwen] witnessed his callousness and violence towards his wife – a wife that only slept on a couch,’ according to the Case Breakers. 

In a recent a phone conversation between Gwen with Poste’s widow, who is now in her late 70s and residing in an assisted living facility, the elderly woman was said to have told her former neighbor: ‘I’m sorry that I didn’t tell the cops about his past.’

A man named Hans Smits told the Case Breakers that over the past 10 years, he had been shielding a ‘Zodiac whistleblower,’ who had allegedly escaped from Poste’s criminal ‘posse’ that was said to have been active in the High Sierra area of California for several decades.

‘Now in his 50s and hiding in the Northwest, [the whistleblower] says he’s angry and ashamed, claiming the psychopath ‘groomed me into a killing machine,” according to the investigative group.

The whistleblower also claimed to have witnessed Poste burying murder weapons.

A woman named Michelle said she was the common-law wife of Poste’s son, and the mother of his grandson, who is now in his 30s. 

According to Michelle, when her 10-year relationship with Poste’s son ended, the house painter sicced two members of his ‘posse’ on her, ordering them to break her windows, harass and assault her, ultimately driving her out of state.
