Karl F. Werner

Nearly two years later, another young woman was found stabbed to death in a wooded park in nearby Saratoga. ^[1] The attacks looked so alike that local authorities called the second killing “a carbon‑copy” of the first. ^[1] When the trail finally led to a 19‑year‑old college student named Karl Francis Werner — a classmate of the first two victims — the revelation shattered the already fragile sense of safety in Santa Clara County. ^[1]

By 1971, Werner would confess to all three murders. ^[1] He was convicted of killing three teenage girls and sentenced to life in prison. ^[1]

This is the story of how those murders unfolded, how investigators finally closed in, and how the case brushed up against the mythology of the Zodiac Killer before ending in a prison cell in Vacaville.

The Almaden Valley Picnic That Never Ended

Fourteen‑year‑old Debra Gaye Furlong and fifteen‑year‑old Kathie Reyne Snoozy lived with their families in a neat, prosperous subdivision in San Jose’s Almaden area. ^[1][2] On August 3, 1969, the friends left their homes to picnic in the nearby hills, the only open area close by where kids could go, as Debra’s father, Glen Furlong, later explained. ^[1][2]

That same evening, their fully clothed bodies were found on a wooded knoll overlooking their homes, on a sun‑baked hillside in southern Almaden Valley, not more than six blocks from where they lived. ^[1][2]

The scene did not immediately make sense. Investigators initially theorized that the girls had been killed somewhere else and then moved, partly because of the lack of blood at the site where they were discovered. ^[1] A “new,” but empty, beer can lay wedged between their bodies, another puzzle with no obvious explanation. ^[2]

Neighbors in the subdivision, jolted by the killings so close to home, described themselves as “very frightened.” ^[2]

“A Frenzied Flurry of Knife Wounds”

Santa Clara County Medical Examiner Dr. John E. Hauser, the county’s chief coroner, handled the autopsies. ^[2] What he found was almost beyond his professional experience.

He said the girls had died in a “frenzied flurry of knife wounds.” ^[1] Debra had more than 100 wounds; Kathie had more than 200. ^[1] Every wound on both girls had been inflicted above the waist. ^[1]

Hauser noted that neither body showed evidence of resistance to the assailant. ^[1] In his many years as a coroner, he said, he had never previously encountered a case with so many knife wounds. ^[1]

The pattern was brutal yet oddly constrained. Hauser observed that the multiple puncture wounds appeared to have been inflicted by one or two small knives. ^[2] The largest wound, he said, was consistent with a pocket knife with about a half‑inch blade. ^[2]

He also remarked that neither girl had been sexually molested. ^[2] Only a small mark on Kathie Snoozy’s hand suggested she may have tried to deflect the knife. ^[2] Hauser said both girls must have died very quickly. ^[2]

The coroner was “puzzled” by many aspects of the slayings and began investigating whether the girls might have been drugged before the stabbing began. ^[2] Blood, skin samples, and stomach contents were sent to area laboratories for examination, with results expected within days. ^[2]

Even amid his clinical language, the scale of the violence seemed to stagger him.

A Community in Shock, and an Investigation With No Clues

While Hauser worked in the morgue, detectives scoured the hills and the neighborhood.

Barton Collins, chief of San Jose detectives, acknowledged that investigators had uncovered no solid clues early on. ^[2] Police and sheriff’s deputies focused on a light‑colored van — they were looking for a Volkswagen, Dodge, Chevrolet, or Ford — in which the girls might have been killed and then rolled, carried, or dragged down the hillside to the grove where their bodies were found. ^[2]

Collins said he and his men had already talked to at least 200 people in search of information about the killer. ^[2] He made his priorities plain: “I’m looking for a killer and it doesn’t matter whether he was under drugs or what.” ^[2]

Friends and schoolmates described Debra as very slim, looking more like a ten‑year‑old than fourteen, “just an ordinary nice girl” who babysat, had a boyfriend, and dreamed of becoming an airline stewardess. ^[2] Neighborhood housewives repeated the same phrase: they were “very frightened” after the murders. ^[2]

Glen Furlong said some people had begun calling his house and hanging up as soon as the phone was answered. ^[2] Even small acts of kindness carried the weight of tragedy — he mentioned that his eldest daughter’s boyfriend had come by to offer condolences. ^[2]

Despite the intensive canvassing, no one was arrested. The murders of Debra Furlong and Kathie Snoozy remained unsolved, a terrifying question mark hanging over the South Bay.

The Zodiac’s Shadow

The brutality and apparent randomness of the Almaden stabbings quickly drew wider attention. San Francisco police inspector Dave Toschi — already deeply involved in the investigation of the self‑proclaimed Zodiac Killer — initially suspected that the Zodiac might have been responsible for the Furlong and Snoozy murders. ^[1]

For a time, the possibility that a notorious, taunting killer had turned his focus to San Jose hovered over the case. At the time of Karl Werner’s eventual arrest, some even considered that he might be the Zodiac himself. ^[1] The Zodiac speculation would not last, but it added another layer of dread and confusion to an already haunting crime.

A Second Murder in the Hills: The Killing of Kathy Bilek

On April 11, 1971, 18‑year‑old Kathy Bilek went to Villa Montalvo, an estate‑turned‑park in Saratoga, to read and birdwatch. She chose a remote, wooded portion of the park near a small stream. ^[1]

She did not return home.

The next day, April 12, Kathy’s father, Charles Bilek, joined Santa Clara County sheriff’s deputies in searching the area around Villa Montalvo. He was the one who found her body while deputies were nearby. ^[1]

The attack on Kathy Bilek had a grim familiarity. She had been stabbed 17 times in the back and 32 times in her chest and stomach. ^[1] The killer, however, had taken care to avoid stabbing her breasts, a detail later noted in the autopsy. ^[1]

Local authorities who compared the Villa Montalvo attack with the 1969 Almaden Valley murders saw too many similarities to ignore. They connected the Furlong/Snoozy slayings with the Bilek murder, publicly calling the latter “a carbon‑copy killing.” ^[1]

For a community still on edge from the unsolved double killing, the implication was devastating: whatever had happened on that Almaden hillside might be happening again.

The Maintenance Man’s Tip

The break came from inside Villa Montalvo. A park maintenance man reported that he had seen the assailant in the area. ^[1] Crucially, he gave police a name: Karl F. Werner, a young man from San Jose. ^[1]

Werner was not an unknown quantity. He was an Oak Grove High School graduate and a student at San Jose City College. ^[1] He had been a classmate of both Debra Furlong and Kathie Snoozy. ^[1]

He had also previously been a suspect in an unsolved knife assault on another woman. ^[1]

Those connections sharpened investigators’ focus. A search warrant for the Werner residence followed. According to reports, the knife used in the Bilek murder was located on the premises. ^[1] For authorities already seeing a pattern between the Almaden and Villa Montalvo slayings, the weapon was a crucial link.

People who knew Werner struggled to reconcile the allegations with the person they thought they knew. One girl who had dated him described him as “accomplished in mathematics” and “not a ‘weird, skulking guy that we picture as a serial killer.’” ^[1]

By then, though, a picture of a very different Karl Werner was coming into focus inside police headquarters.

Confession: Three Murders, Two Crime Scenes

In September 1971, months after Kathy Bilek’s death, 19‑year‑old Karl Francis Werner confessed to the murders of Debra Furlong, Kathie Snoozy, and Kathy Bilek. ^[1]

The confession tied together two crime scenes and three victims spanning nearly two years. It also undercut the lingering suspicion that the Zodiac Killer had been involved. At the time of Werner’s arrest, investigators had considered whether he might, in fact, be the Zodiac. ^[1] But it was subsequently determined that Werner had been residing in Marlborough, Massachusetts at the time of some of the earlier Zodiac slayings, making that identification untenable. ^[1]

Conviction and a Life Sentence

Karl Werner was ultimately convicted of murdering three teenage girls in Santa Clara County between 1969 and 1971. ^[1] The convictions covered the killings of Debra Gaye Furlong, Kathie Reyne Snoozy, and Kathy Bilek, and were recorded as three counts of first‑degree murder. ^[1]

For those crimes, Werner received a life sentence. ^[1]

In the years that followed, he was incarcerated at the California Medical Facility in Vacaville, a state prison that houses many long‑term and medically complex inmates. ^[1]

The arc from Almaden’s hillside to a prison cell was complete. Officially, the “carbon‑copy” killer had been identified, had confessed, and had been removed from the community he had terrorized.

Who Was Karl Francis Werner?

Aftermath and the Weight of Unanswered Why

The physical facts of the case are scrupulously documented: the dates, the locations, the stab counts, the weapons, the confessions, the sentences. ^[1]

What lingers are the human traces left around those facts.

A father explaining that the hills where his daughter died were simply the only open space nearby where kids could go. ^[2] Neighbors in a “neat, prosperous subdivision” admitting they were “very frightened.” ^[2] A coroner, seasoned by years of grim work, openly saying he was “puzzled” by the case. ^[2] A onetime girlfriend insisting that the accused killer she knew was an “accomplished” student, not the caricature of a predator. ^[1]

The official record can say who, when, and how. In the case of Karl Francis Werner, it can even say how many times. But for the families of Debra Furlong, Kathie Snoozy, and Kathy Bilek, and for a community that watched its open spaces turn ominous, the most haunting part may be the question that the record does not answer: why any of it had to happen at all.
