How Was Zodiac Cipher Solved

In 1969 and 1970, the Zodiac transmitted four cryptic signals to the newspaper. The first had 408 characters and took a week to crack. The second was a 340-character cipher that was just cracked. Following that, the killer sent two very brief ciphers, one of which had only 13 characters and the other only 32. An engineer in France claimed to have solved them in January 2021, but Blake is skeptical. He claims, “They’re both too short to have a unique solution.”

How was the Zodiac encryption cracked?

The Zodiac Killer sent out four ciphers along with letters explaining his crimes in 1969 and 1970. The first, which was sent on July 31, 1969, was decrypted a week later.

The cipher, Z408, read, “I like killing people because it is so much pleasure.” “Because man is the most dangerous animal of all, it’s more enjoyable than killing wild game in the wilderness.”

Authorities were mocked by the cipher, which was mailed to The San Francisco Chronicle with a victim’s bloodstained shirt. “I hope you’re having a great time trying to catch me,” wrote the Zodiac Killer.

Is the Zodiac murderer’s code cracked?

The F.B.I. had acknowledged that a team of three hobbyist cryptologists had solved a second cipher, containing 340 characters, 51 years later, with a code-breaking program that ran through 650,000 possible solutions before finding the encryption key, according to a French magazine article Mr. Ziraoui read in December. The message, however, contained no information concerning the killer’s identity.

That left two unresolved codes: one with 32 characters and the other with 13 characters preceded by the phrase “My name is .”

What method did they use to figure out who the Zodiac killer was?

According to the Case Breakers, a group of more than 40 former police investigators, journalists, and military intelligence personnel, Gary Francis Poste is the Zodiac Killer. The investigation was based on forensic evidence, images discovered in Poste’s darkroom, and part of the serial killer’s coded notes, according to the investigators.

How was the Zodiac Killer apprehended?

The Case Breakers, a group of former law enforcement personnel, prosecutors, and intelligence officers, announced on Wednesday that they had identified the perpetrator responsible for a string of murders in the San Francisco Bay Area in the late 1960s.

The investigation into the killings, however, is still ongoing, according to authorities. Law enforcement receives tips regarding the case on a daily basis, including from those who believe they know who the culprit is.

The Zodiac killer committed a series of murders in the San Francisco Bay Area in the late 1960s and is still considered one of America’s most notorious cold cases. Despite the media attention this week, some police officers and investigators remain doubtful of the purported development. The Zodiac has remained in the news for years, with new hypotheses emerging all the time.

The Case Breakers said they had new physical and forensic evidence as well as eyewitnesses to back up their theory that the killings were committed by an air force veteran who died in 2018.

“Tom Colbert, a member of the Case Breakers, told the San Francisco Chronicle, “I certainly believe we solved this case.”

The FBI and the San Francisco Police Department both declined to comment on the news, but both stated that the investigation was still ongoing.

“The investigation into the Zodiac Killer by the FBI is still ongoing and unresolved. We will not be giving further information at this time due to the ongoing nature of the investigation and out of respect for the victims and their families,” the FBI’s San Francisco office said in a statement.

In a press release, the Case Breakers said they based their identification on images of the suspect showing scars on his forehead that match a police sketch of the Zodiac. The suspect’s name was also found in anagrams supplied by the Zodiac, according to the team.

Between 1968 and 1969, the Zodiac terrorized northern California communities and claimed the lives of five people. He may potentially be involved in other crimes, according to police. Numerous documentaries have been made about the deaths, as well as the 2007 thriller Zodiac.

According to a 1975 FBI letter released by the Case Breakers, the killer is also responsible for the 1966 murder of Cheri Jo Bates in Riverside, which the FBI may have revealed at one point. Bates’ assassination was not linked to the Zodiac, according to local police.

After sending taunting messages and ciphers to local media, threatening to commit greater violence if his letters were not reported, the Zodiac Killer gained notoriety.

A team of experts cracked the code to a 1969 cipher the Zodiac sent to the San Francisco Chronicle in 2020, though law enforcement stated it didn’t help investigators at the time.

“I hope you’re having a good time trying to catch me,” reads the message, which was transmitted in a series of symbols. “I’m not afraid of the gas chamber since it will speed up my arrival in heaven because I now have enough slaves.”

The arrest of the Golden State Killer in 2018 stoked hopes that the Zodiac would finally be identified as detectives utilized forensic genealogy to link a former police officer to decades-old rapes and killings. However, unlike that case, no DNA from any of the Zodiac killings has been confirmed. By examining saliva traces from a stamp on a letter delivered by the Zodiac, police were able to develop a partial profile, although it can only be used to rule out suspects.

What was the origin of the Zodiac killer’s moniker?

The press began to refer to him as the ‘Zodiac Killer,’ but it is unclear why the killer chose that moniker.

In addition, he would sign his letters with a circle and a cross over it, which resembled a target or a coordinate symbol.

The signature symbols, according to authorities, were designed to symbolize coordinates that could indicate future killing locations.

Is it true that Jack the Ripper was ever apprehended?

According to forensic specialists, they have finally identified Jack the Ripper, the renowned serial killer who haunted London’s streets more than a century ago. Aaron Kosminski, a 23-year-old Polish barber who was a prime police suspect at the time, has been identified by genetic tests disclosed this week. However, detractors argue that the evidence is insufficient to consider the matter closed.

The findings came from a forensic investigation of a stained silk shawl discovered close to the mangled remains of Catherine Eddowes, the killer’s fourth victim, in 1888, according to authorities. The shawl is flecked with blood and semen, the latter of which is thought to be from the killer. Four other women were murdered in London over the course of three months, and the perpetrator has never been identified.

Kosminski has previously been linked to the crimes. However, this is the first time the DNA evidence supporting the claim has been published in a peer-reviewed journal. Jari Louhelainen, a biochemist at Liverpool John Moores University in the United Kingdom, conducted the initial genetic testing on shawl samples several years ago, but he claimed he wanted to wait until the controversy died down before releasing the results. In his 2014 book, Naming Jack the Ripper, author Russell Edwards, who bought the shawl in 2007 and donated it to Louhelainen, utilized the unpublished results of the tests to identify Kosminski as the murderer. However, geneticists argued at the time that assessing the claims was hard due to a lack of technical specifics concerning the study of DNA samples from the shawl.

Up to a degree, the new study lays them out. Louhelainen and his colleague David Miller, a reproduction and sperm expert at the University of Leeds in the United Kingdom, describe extracting and amplifying DNA from the shawl in what they call “the most systematic and most advanced genetic analysis to date regarding the Jack the Ripper murders.” The studies compared mitochondrial DNA fragments extracted from the shawl with samples received from living descendants of Eddowes and Kosminski. They determine in the Journal of Forensic Sciences that the DNA matches that of a living cousin of Kosminki.

The study also reveals that the killer had brown hair and brown eyes, which is consistent with eyewitness testimony. The authors admit in their research that “these qualities are certainly not unique.” However, the researchers point out that blue eyes are currently more frequent than brown in England.

Critics are unlikely to be pleased with the results. The study omits key facts about the genetic variants that were discovered and compared between DNA samples. Instead, the authors use a graphic with a sequence of colored boxes to depict them. The shawl and current DNA samples matched where the boxes overlapped, they said.

The scientists claim in their research that the Data Protection Act, a British regulation designed to preserve people’s privacy, prevents them from disclosing the genetic sequences of Eddowes and Kosminski’s living relatives. They claim that the visual in the study is easier to understand for nonscientists, particularly “those interested in genuine crime.”

The authors should have included mitochondrial DNA sequences in the paper, according to Walther Parson, a forensic scientist at the Institute of Legal Medicine at Innsbruck Medical University in Austria. “Otherwise, the reader will be unable to assess the outcome. I’m curious where science and research are headed if we start presenting colored boxes instead of findings.”

Hansi Weissensteiner, a mitochondrial DNA expert at Innsbruck, also has reservations about mitochondrial DNA testing, claiming that it can only conclusively prove that two peopleor two DNA samplesare unrelated. “Mitochondrial DNA can only be used to rule out a suspect.” To put it another way, the shawl’s mitochondrial DNA may have come from Kosminski, but it could equally have come from the thousands of people who resided in London at the time.

Other skeptics of Kosminsky’s theory have pointed out that the shawl was never found at the crime site. They also believe it could have grown polluted over time.

The new tests aren’t the first to try to use DNA to identify Jack the Ripper. Patricia Cornwell, a crime writer in the United States, encouraged other experts to look for DNA in samples collected from letters allegedly delivered by the serial killer to police a few years ago. She said the killer was the painter Walter Sickert based on the DNA study and other indicators, despite many experts believe the letters were phony. The murderer could have been a woman, according to another DNA study of the letters.

Is it possible that Vaughn is the Zodiac Killer?

Robert Graysmith couldn’t resist his curiosity on a rainy September night in 1978.

An anonymous phone call about the identity of the Zodiac, the legendary Bay Area serial murderer, had been received by the San Francisco Chronicle cartoonist a month before. At the outset of an hour-long chat, the mystery voice said, “He’s a person named Rick Marshall.” The serial killer’s spate of murders had gone unsolved since 1969, but Graysmith had a new clue. Marshall, a former projectionist at The Avenue Theater, had stashed evidence from his five victims inside movie canisters that he’d rigged to explode, according to the informant. The anonymous caller instructed Graysmith to locate Bob Vaughn, a silent film organist who worked with Marshall, before hanging up. Graysmith discovered that the booby-trapped canisters had recently been transferred to Vaughn’s house. “Get to Vaughn,” said the voice. “See if he warns you not to go near any of his movie collection.”

Graysmith went into Marshall’s history after years of working separately on the case and discovered significant coincidences. His new suspect was a fan of The Red Spectre, an early-century film mentioned in a Zodiac letter from 1974, and had used a teletype machine similar to the killer. Marshall’s felt-pen posters outside The Avenue Theater even contained calligraphy that was comparable to the Zodiac’s strange, cursive strokes. Graysmith witnessed Vaughn playing the Wurlitzer and the Zodiac’s crosshair symbol plastered to the theater’s ceiling on his occasional visits to the upscale movie house. There were just too many indications that overlapped. He needed to get to Vaughn’s residence. “We realized there was a connection,” Graysmith says. “I was paralyzed with fear.”

Graysmith’s nightmarish encounter was converted into one of the creepiest movie scenes of all time by filmmaker David Fincher almost three decades later. It happens near the end of Zodiac, as Graysmith (Jake Gyllenhaal) drives Vaughn (Charles Fleischer) home in his bright-orange Volkswagen Rabbit through the rain. The atmosphere rapidly becomes unsettling once inside. Vaughn brings a scared Graysmith down to his dimly lit basement after revealing that he, not Marshall, is responsible for the movie poster handwriting. The floorboards above Graysmith groan as the organist looks through his nitrate film records, implying the presence of someone. Graysmith races upstairs to the closed front door, rattling the handle, before Vaughn slowly pulls out his key and opens it from behind, after Vaughn convinces his guest that he lives alone. Graysmith dashes into the downpour, as if he’s just escaped the hands of the Zodiac.

In the end, the encounter in the third act is a red herring. Vaughn was never thought to be a serious suspect. However, in a film full of routine cop work and dead ends, just five minutes of tense tension transform a procedural into actual horror. The moment represents a culmination of Graysmith’s neurotic preoccupation with the Zodiac’s identitya glimpse into the life-threatening lengths and depths to which he’ll go to solve the caseas well as a brief rejection of the film’s otherwise objective gaze. “It’s actually so distinct from the rest of the movie,” explains Zodiac screenwriter James Vanderbilt. “It does give you that jolt that a lot of the movie is attempting to avoid.”

Simply put, the basement sequence is a classic Fincher adrenaline rush, bolstered by years of meticulous research, meticulous attention to detail, and last-minute studio foresight. Graysmith still gets shivers when he sees the movie, even though it was released thirteen years ago.

Graysmith had a theory about who the Zodiac was.

The film describes an encounter between Robert Graysmith and Arthur Leigh Allen, whom he thinks to be the Zodiac Killer. Graysmith enters the hardware store where Allen works and the two stare each other down, which is quite close to what happened in real life.

Graysmith alleges he went to Allen’s hardware store, where Allen pulled up alongside him in the parking lot, blocking the driver’s car door, and the two locked eyes.

What was the pattern of the Zodiac killer?

According to the stories of the few survivors of documented Zodiac attacks, the Zodiac donned black attire of various types (according on the month) and, at least on one occasion, a dark hood emblazoned with the Zodiac emblem.

He used a variety of weapons, including an automatic handgun (of various sorts) and bladed weapons, most notably a military-style knife, to execute some of his victims. According to one of his letters, he had a pencil-sized flashlight strapped to his revolver during the Christmas shootings so he could shoot in the dark.

The Zodiac’s regular strategy of attack was to target Caucasian adolescent couples and kill them by shooting them or stabbing them with a knife while they were in a quiet area (usually lover’s lanes) and/or in a car. His approach to them is said to have changed over time. He stepped up to the car and started firing at Mageau and Ferrin without saying anything, while during the Hartnell-Shepherd stabbing, he pretended to be a robber before telling Shepherd to tie up Hartnell with some pre-cut lengths of rope and then tying her up himself. He pretended to be an escaped convict who had killed a guard and needed their car and money to travel to Mexico for the second homicide. He got into his taxi and shot Paul Stine in the head with a 9mm pistol, then removed his wallet, car keys, and a bloodied piece of his shirt, which he later sent to The Chronicle. He also acted in places where jurisdictions overlapped, very likely on purpose, to slow down the authorities. He claimed to have killed several of his victims “by fire” and “by rope” in one of his messages. Though the Zodiac was tied to strangulation instances (the Santa Rosa hitchhiker killings), no cases of arson were ever linked to him.

After the Ferrin-Mageau and Hartnell-Shepard attacks, he used a pay phone to telephone whichever police department was nearest to the scene and claim credit for the crimes.
