It’s a mystery that has endured for more than half a century. The Zodiac Killer terrorized Northern California in the late 1960s with a series of unsolved slayings. While he was active, he mocked the police with taunting messages and bizarre ciphers and cryptograms that he sent to newspapers and radio stations. Zodiac claimed responsibility for a series of shootings and stabbings, probably grossly exaggerating the number of his victims. Decades of investigation and extensive publicity produced suspects, but never conclusively identified the killer.

The First Zodiac Murders

Historians generally agree that the first Zodiac killing occurred on December 20, 1968, near Vallejo, California. An unknown assailant shot high school students David Faraday, 17, and Betty Lou Jensen, 16, while they were parked on Lake Herman Road. Jensen’s body lay several yards from the vehicle, while Faraday’s was near the car. Both died from their wounds. At the time, authorities had no clear indication that the killings were part of a larger series.

On July 4, 1969, the killer attacked another young couple in a parked car at Blue Rock Springs Park in Vallejo. Darlene Ferrin, 22, and Michael Mageau, 19, both suffered multiple gunshot wounds. Ferrin died, but Mageau survived despite grievous injuries. Shortly after the attack, a man called the Vallejo Police Department and claimed responsibility for the shooting. The caller also referred to the Lake Herman Road murders, linking the two crimes.

Zodiac Opens a Publicity Campaign

Later in July, newspapers in the San Francisco Bay Area received nearly identical letters from someone claiming to be the killer. Each letter included part of a 408-symbol cipher. The writer demanded that the papers print the messages on their front pages and threatened further violence if they didn’t. The letters concluded with a crosshair-like symbol as a signature. The symbol later became closely associated with the Zodiac name.

Within days, a Salinas, California, couple with no professional experience in cryptography, Donald and Bettye Harden, solved the cipher. The decoded message stated that the killer enjoyed murdering people and suggested that his victims would serve him in the afterlife. The message did not reveal the writer’s name.

In another letter received in early August 1969, the writer used the phrase, “This is the Zodiac speaking,” marking the first known use of the name that would define the case. The letters, and the symbols that accompanied them, became central to the investigation and to public awareness of the crimes.

The Zodiac Attacks Continue

On September 27, 1969, college students Bryan Hartnell and Cecelia Shepard were attacked at Lake Berryessa in Napa County. The assailant approached wearing a fearsome-looking hood with the Zodiac symbol on the chest. He tied the pair and stabbed them repeatedly. Hartnell survived, but Shepard died two days later. Before leaving, the attacker wrote dates of earlier crimes on the door of Hartnell’s Volkswagen Karmann Ghia and signed it with the Zodiac symbol.

The next confirmed killing occurred on October 11, 1969. A man hailed a cab in the Union Square area of downtown San Francisco and instructed the driver, Paul Stine, to take him to Washington and Maple streets in Presidio Heights. The cab traveled one block further to Washington and Cherry, where the passenger shot Stine in the head, killing him. The killer then removed part of Stine’s shirt and left the scene. Several days later, a letter sent to the San Francisco Chronicle included a piece of the bloodstained fabric, providing strong evidence that the writer was connected to the murder.

The Stine killing prompted an intensified police response, in part because officers had been close to the crime scene shortly after the shooting. The initial police radio description incorrectly identified the suspect as a Black male, and two officers later reported seeing a White man walking nearby. By the time police corrected the error, the individual had disappeared.

More Messages from the Killer

The Zodiac continued writing to newspapers and authorities. Some letters contained additional ciphers, threats, diagrams, references to police activity, and claims of other killings. The writer sometimes took credit for crimes that law enforcement agencies could not definitively connect to Zodiac. As a result, it has been difficult to pin down the total number of Zodiac victims.

Among the most closely studied messages was a 340-character cipher mailed to the San Francisco Chronicle in November 1969. It resisted solution for more than 50 years. In December 2020, an international team of codebreakers announced that it had solved the cipher. The message again taunted authorities and referred to the killer’s beliefs about death, but it did not disclose an identity.

Suspects in the Zodiac Case

The investigation generated a long list of suspects. One of the best-known was Arthur Leigh Allen, a Vallejo resident whom police questioned. Allen later became the focus of intense public speculation. Investigators examined his background and possessions, and some circumstantial details pointed to him. However, no conclusive physical evidence established Allen as the Zodiac Killer. He died of a heart attack in 1992 without being charged in the case.

Investigators, authors, journalists, amateur researchers, and relatives of deceased men have proposed other suspects. Some claims have attracted national attention, particularly when someone announces that they believe they have identified the killer. Law enforcement agencies generally respond cautiously, noting that the case requires evidence that can withstand formal scrutiny.

The Zodiac case became notable not only for the killings but also for the offender’s manipulation of the media. By sending letters, issuing threats, and creating puzzles, the killer expanded the investigation beyond individual crime scenes and forced newspapers and police departments to respond publicly. The correspondence also challenged investigators, who had to determine which letters were authentic and which were copycats.

Epilogue

Nearly sixty years after his last confirmed murder, the Zodiac Killer remains unidentified. Like Jack the Ripper and the Black Dahlia slayer, his identity is likely to remain a mystery, one of the things that makes the case so enduring.

The Zodiac killings inspired numerous films that either depict fictionalized versions of the crimes and investigation or use elements of the case as plot devices. The latter includes the 1971 film Dirty Harry, starring Clint Eastwood.

W. Haynie Gourley, a prominent Nashville, Tennessee, businessman, left his Capitol Chevrolet dealership on the morning of May 24, 1968, for what he expected to be a short drive. Within minutes, the 72-year-old businessman was dead and his associate wounded. The murder case that unfolded dominated local headlines for months.

Gourley was the founder and president of Capitol Chevrolet, a dealership he had established in 1932 during the Great Depression. By 1968, the company had become one of Nashville’s leading automobile businesses and had recently moved into a large new facility on Murfreesboro Road. Gourley had many friends in business and civic circles and had headed automobile trade organizations.

The Fatal Car Ride

Accompanying Gourley that morning was William E. Powell, Capitol Chevrolet’s executive vice president and minority shareholder. Powell had worked at the dealership since 1965 and owned 25 percent of the company stock. In the days before the shooting, the Gourley family and Powell had been discussing the future of the business. Gourley wanted his son, William Haynie “Billy” Gourley Jr., eventually to take control, and Powell had discussed selling his interest and leaving Capitol Chevrolet altogether.

At approximately 11 a.m., Gourley and Powell left the dealership for a brief drive to “discuss business.” Their route took them along Elm Hill Pike. What happened during that trip became the central question in one of Nashville’s most closely watched criminal investigations.

Powell told police that near Spence Lane, an African American man entered the back seat of the automobile, displayed a gun, and demanded money. According to Powell, the assailant opened fire when Gourley reached for his wallet. Three bullets struck Gourley, killing him, while Powell suffered a gunshot wound to his leg. Powell then drove Gourley back to the dealership before calling police and an ambulance.

The Investigation Begins

The timing was unfortunate. Only weeks earlier, an assassin had murdered Martin Luther King Jr. in Memphis. Nashville had experienced subsequent racial tension, culminating in several National Guard deployments. Haynie Gourley’s murder, stoked by intensive press coverage, put the city on edge.

The case received extraordinary press attention. The Nashville Banner issued an extra edition on May 24, its first since the assassination of President John F. Kennedy in 1963. Rewards offered by the City of Belle Meade and the Nashville Automobile Trade Association eventually totaled $12,000 (over $113,000 in 2026).

Investigators quickly began searching for the gunman Powell had described. Authorities questioned numerous Black men while police searched the Elm Hill Pike area for evidence. Yet despite the publicity and the rewards, the initial Metro police investigation produced no viable suspects. One man questioned soon after the killing had an alibi. Another man whom Powell later said resembled the assailant proved to have been in California on the day Gourley died. Investigators also examined physical evidence from the automobile and searched extensively for the weapon.

As the investigation continued, authorities began focusing on Powell himself. Gourley’s wallet had not been taken, and detectives scrutinized both the physical evidence and the men’s business relationship. In March 1969, a Davidson County grand jury indicted Powell on a charge of first-degree murder.

William Powell on Trial

The resulting trial became a major event in Nashville. Judge Allen Cornelius presided. District Attorney General Thomas Shriver prosecuted the case with attorney John J. Hooker Sr. serving as special prosecutor. Cecil Branstetter and Jack Norman Sr., two of the city’s best-known lawyers, represented Powell.

The prosecution’s case was largely circumstantial. The state presented testimony concerning the business arrangements at Capitol Chevrolet and called a witness who said he had seen a black automobile containing only two men shortly before hearing gunshots. The defense challenged that witness’s recollection and introduced testimony questioning whether he had been at the location he described.

Another dramatic development involved a rusted .38-caliber Smith & Wesson pistol found along Elm Hill Pike months after the killing. Because of its condition, investigators could not conclusively establish that it had fired the bullets that killed Gourley. The judge did not permit the pistol itself to be introduced after the prosecution had rested its case, although he did allow additional testimony concerning the weapon. A former Capitol Chevrolet employee testified that he had once supplied Powell with a similar handgun. Powell denied receiving or owning it.

Powell also testified in his own defense and maintained the account he had given from the beginning: that a third man had entered the automobile and opened fire. He denied killing Gourley.

On August 2, 1969, after nearly five hours of deliberation, the jury returned a verdict of not guilty.

Epilogue

The acquittal ended the prosecution of William Powell, but it did not solve the murder. No other person was convicted of killing W. Haynie Gourley. Decades later, the Metropolitan Government Archives still preserve about 2,400 pages of trial records and dozens of photographs from the proceedings. The documented facts end with a prominent businessman dead, the only surviving witness acquitted of his murder, and the identity of the killer unresolved.

Bill Powell gained control of Capitol Chevrolet and ran it for many years. Carl Black opened Carl Black Chevrolet on June 2, 2003, taking over the building at 600 Murfreesboro Road. In 2015, Metro Nashville demolished the Capitol Chevrolet site and built a new police headquarters building there.
