Zodiac Killer: Behind the Scenes

By Tom Voigt | Founder: Zodiackiller.com | tomvoigt@zodiackiller.com

Long before the existence of current Internet staples such as Facebook, Google and YouTube, Zodiackiller.com was already just a click away. It was March 1998, and the web was a much different place. Most surfers used AOL and paid by the minute. Downloading a simple picture often took forever, and the material available online was extremely limited. Want to see a document or record? Click here for the mailing address! Of course, all things Internet are better now. And while I am thankful the days of the web’s infancy are long gone, in 1998 I was about to learn that something is lost when something is gained.

Thanks to Zodiackiller.com, since 1998 I have met many key players in the Zodiac case. Of those key players, Mike, Ken and Nancy became my friends. They have since passed away. Without Mike, Ken and Nancy, this website would not be where it is today. I wanted this update to be about them.

San Francisco Police Dept. Inspector Mike Maloney (and his partner, Inspector Kelly Carroll) was the last investigator in his department to really work the Zodiac case. As a result, in 2001 new forensic evidence was uncovered that could one day help identify the Zodiac killer. Maloney retired soon after and immediately became a great source of info for this website, going so far as giving me the scoop of a lifetime that was soon reported around the world by every major news source you can imagine. Most of my contact with Mike was via e-mail, but one night in 2004 he met with a group of us amateur detectives at The Blarney Stone, a bar around the corner from where I was living at the time in San Francisco. Mike was a big, strong guy, dressed in black leather, his long hair pulled back. After retiring from the force, Mike decided he wanted to learn to play the bass guitar. He sure looked the part. It was a fun night, and Mike generously bought several rounds of beer. He didn’t mind answering our questions about the Zodiac case, or listening to our ideas. Mike appreciated what we could contribute. He was good like that. A few years earlier, Mike had taken a major role in a documentary film that was about both my website and its users who were trying to solve the case. In March 2007, that film, Hunting The Zodiac, was set to debut at the 4 Star Theater in San Francisco. Mike was scheduled to be one of the featured guests. I had privately seen the film a few months earlier and knew Mike would love it. Plus I was looking forward to seeing him again. Three weeks before the film’s debut, I received a call from the filmmaker, John Mikulenka: Mike Maloney had unexpectedly passed away from a heart issue. All these years later, I still can’t believe it.

After retiring from show business, Stan Laurel (of Laurel and Hardy fame) kept his home number listed in local telephone directories; he wanted his fans to be able to contact him. Retired Napa County Sheriff Ken Narlow did the same, but the call he desired was from a serial killer, the Zodiac. That call apparently never came. However, many a time did Ken receive calls from people like me, people wanting to obtain or share information about the Zodiac case. Ken was all ears; he always made time. Once, I spoke to him for a good length of time before learning he was at a cocktail party. Another time, near the end of our call, Ken apologized for talking with his mouth full; he had been in the middle of dinner. Didn’t matter, Ken was always there for you. My first meeting with Ken was at a Lyon’s restaurant in Napa. A few years later, Ken met with a group of us at a local park. Several times I was a guest in his home, the last such occasion just a few months before he died. Ken had developed cancer and was putting up a great fight, but it was taking its toll and he was very weak; difficulty walking, wounds on his arms that just wouldn’t heal. Still, he had guests and was determined to be a great host, insisting on retrieving wine from the cellar even though he couldn’t even stand up without assistance; I had to pull him up from the sofa. Some nights, Ken told me, he was too weak to move, so he would sleep on the floor of the living room. During our last meeting, we drank wine, and then Ken took me into his office, limping all the way, to find a Zodiac police report he wanted to show me. Up until the very end, Ken never stopped answering that phone. Stan Laurel would be proud.

Everyone has one of those nutty “a-friend-of-a-friend” stories. Such a situation is how I found Nancy Slover. Ever since I could remember, I had wanted to find Nancy, the Vallejo police dispatcher who spoke with the Zodiac back in July 1969 and then seemed to vanish from the face of the Earth. As fate would have it, a woman who once knew Zodiac suspect Arthur Leigh Allen back in the 1970s happened to follow this website. She contacted me and mentioned she was old friends with Nancy. I could not believe my luck. I had Nancy on the phone within the hour! She appeared guarded at first and didn’t seem to believe that I had trouble locating her. Nancy actually thought nobody cared enough to find her, ask her questions, get her story. Boy, she quickly learned just how wrong she was. Didn’t stop her from teasing me, though. “Now Tom, all you had to do was visit the City Recorder’s office and you would have found me right away!” she reminded me often. Well, better late than never, and we quickly made up for lost time. Nancy became the star of the Zodiac world overnight. Everyone wanted to meet her and she was glad to accommodate, appearing at three public gatherings organized by this website. Nancy’s love was her adorable Chiweenie named Chico. On my research trips to the Bay Area, I always looked forward to visiting with Nancy at her home in Benicia, walking Chico, and having cocktails with Nancy at her favorite hangout, the Vets Hall. Unfortunately, Nancy’s considerable health problems continued to mount, to the point she told me she didn’t really feel like a person anymore. That was one of the last times I spoke with her. Eventually, I found myself back in San Francisco and planning to see her. My first morning in The City, I awoke to a voicemail from a mutual friend explaining that Nancy had died. I haven’t been back since. One day I know I’ll return to my favorite place, but things will never be the same.

In those good old days, I was fortunate to drink beer with Mike, wine with Ken, and booze with Nancy. Slow downloads weren’t so bad after all.

The Jim Dunbar Show

On Oct. 22, 1969, a man claiming to be the Zodiac killer called a live San Francisco television show. The guest on the show was famed attorney Melvin Belli, and the show’s host was Jim Dunbar. Mr. Dunbar’s operator patched the caller through so the entire Bay Area could hear “Zodiac’s” voice. It was suggested the caller be referred to as “Sam” during the conversation.

Later that day, the only three living people in the world to hear the real Zodiac’s voice — Nancy Slover, David Slaight and Bryan Hartnell — were brought to the television studio to see if they could recognize the caller’s voice. After careful scrutiny, all three concluded the voice was unfamiliar. It was eventually determined the calls were made by a mental patient. Less than two months later, the real Zodiac killer wrote a letter to Belli.

Gaikowski Audio

In 1986, a former friend began to suspect that San Francisco resident Richard Gaikowski (pictured above) was the Zodiac killer. That friend made the recordings featured below. Eventually, Gaikowski’s recorded voice was played to Nancy Slover, who had spoken with the Zodiac in July 1969. Slover’s reaction to Gaikowski’s voice is included below.

Betty and David

Tragedy on the outskirts of town

By Tom Voigt | Founder: Zodiackiller.com | tomvoigt@zodiackiller.com

As far as their parents knew, teenagers David Faraday and Betty Jensen were on their first official date, although the two had been seeing each other in secret whenever their schedules allowed. Students at separate Vallejo high schools, each had a spotless reputation.

The Lake Herman Road victims: Betty Jensen and David Faraday (Zodiac case # V-25564)

On the night of Dec. 20, 1968, David (age 17) and Betty (age 16) were found shot to death outside of their parked vehicle in a gravel turnout along rural Lake Herman Road. There were no witnesses and little evidence. After an exhaustive investigation, detectives could not establish a motive for the attack, ruling out revenge, robbery and sexual molestation. Eventually, the young couple’s elusive killer would write anonymous letters claiming responsibility:

The first writings. Shortly thereafter, the author began calling himself “the Zodiac”

Downtown Vallejo in 1968

Years later, Betty’s best friend, Sharon, revealed to me details about what happened the night of the murders:

“David called me and told me that he was going to ask Betty to go steady with him. Then he asked me if I thought she would accept. Of course I said yes; she liked him an awful lot. He was going to give her a ring. He asked me where they could go to be alone. Everybody used to park at St. Catherine’s Hill and get run off by the police. He didn’t want to go there and asked me where else they could go to be alone. I told him to go to Blue Rock Springs Park. That’s something I never told the cops. I just assumed that’s where they were going to go.”

Instead, the pair ended up at Lake Herman Road, a very secluded location quite familiar to local teens. Said Sharon:

“When we had driver’s ed, that’s one of the roads the teachers used to take us on because there wasn’t much traffic.”

David Faraday was shot once behind the ear as he exited the vehicle

Betty Jensen was shot multiple times in the back as she ran for her life

Eventually, several of David’s classmates sent me messages through Zodiackiller.com.

From Rob:

“On the afternoon of December 20th, 1968, I gave Dave a couple of cigarettes. It was lunch time and I was on the other side of the railroad tracks smoking my Marlboros. You had to smoke down there as it was off school property. Anyway, Dave trotted up from the non-school side and asked for a cigarette. I remember looking at him funny and asking him what he was doing smoking. He didn’t say anything, but held up one of his arms. (I recall that Dave was on the wrestling team.) It had a heavy bandage or a light cast on it. I gave him a couple of cigarettes and he said thanks and trotted off. That’s the last time I saw him and of course he was murdered later that night.  Dave was a very nice young guy. It was a damn shame he bought it that way. I still take out my battered yearbook on rare occasions and look at his picture.”

From Mike:

“I grew up in Vallejo and remember well the morning I saw Dave Faraday’s picture in the paper as a victim of the Zodiac (although no one called him that yet).  I knew him from Boy Scout summer camp where he was a counselor.  He was a couple years older than me and had these way cool moccasin/boots with fringe.  Why couldn’t my parents buy me cool footwear like that?”

From Tommy:

“I lived in Vallejo in 1968 on Sereno Dr. two doors up from the Faraday’s house.  I remember when David was killed we drove by the Faraday’s house and the Rambler was getting towed to their driveway with the window shot out.  I’ll never forget that sight.”

The crime scene along Lake Herman Road

Lake Herman Road has a long history of folklore, probably because of its isolated — and overall spooky — setting. Here are a couple of such stories that were submitted by a visitor to Zodiackiller.com:

“A story I’ve heard about Lake Herman Road was that a long time ago, there was a schoolhouse out there. It caught on fire, and people could see the burning children. Several old timers have told me this same story, but exactly when the fire happened, or any details about the school, nobody knows. Recently, a friend of mine said that when he was driving down Lake Herman Road at night, he saw the ghost of a girl standing on the side of the road; he could see through her, and a wet dog was by her side.”

Located at an isolated spot in the hills over Lake Herman Road was yet another piece of folklore. Called “the Zodiac Shack,” it was rumored by locals to be the old hideout of the Zodiac killer

On the 30th anniversary, I’m pictured at Betty’s final resting place. We later added fresh flowers

Still on the 30th anniversary, I visited the crime scene with retired police officer Steve Baldino (pictured). At the time of the Zodiac crimes, Baldino worked for the Vallejo police

While both families were deeply impacted by the murders of Betty and David, Betty’s mother, Virginia, was particularly devastated. Said Sharon:

“I went to see her mother one time and her mother talked about Betty Lou like she was still alive. I couldn’t deal with that because I was only 16. She’d talk as if Betty Lou were in her room, talked of her in the present tense. I never went to see her again.”

The Old, Buried Bomb

“bus goes bang car

pass es by ok.” —

The Zodiac’s threat from Nov. 9, 1969

By Tom Voigt | Founder: Zodiackiller.com | tomvoigt@zodiackiller.com

In October 1969, the Zodiac killer mailed a letter in which he threatened to shoot out the tire of a full school bus and then kill the children within. In another letter the following month, the Zodiac made a second threat against children when he revealed plans to hide a bomb along an unnamed road. According to the Zodiac, the road bomb was designed to specifically target a school bus. Thankfully, no such attack ever happened. And no such possible bomb was ever found…until Jan. 31st, 2015.

The envelope containing the Zodiac’s bomb threat

The Zodiac’s bomb diagram

Before we get to that old, buried bomb found in 2015, let’s first briefly examine the necessary location requirements for the Zodiac killer’s roadside school bus bomb.

Obviously, the Zodiac would have needed a stretch of road that featured school bus traffic. Easy enough.

It’s important to remember the Zodiac’s threat was to specifically target a school bus. He also claimed the roadside bomb would somehow be activated by a vehicle’s height. Therefore, the location of the bomb would have needed to be somewhere with school bus traffic, but relatively free of traffic from vehicles similar in height to a school bus, such as a regular bus used for public transportation.

The Zodiac would have also needed privacy while installing his roadside bomb. Therefore, a rural setting would have been mandatory.

Finally, a flat area with good visibility in all directions would have been a requirement, allowing the Zodiac to spot potential intruders in advance and conceal what he was doing.

Recap:

To install his roadside school bus bomb, the Zodiac killer would have needed —

*A road with school bus traffic

*A road that lacked vehicles of the same height as a school bus

*A flat stretch of seldom-used road with good visibility in all directions

The Zodiac described his bomb as a “death machine

While we associate the Zodiac killer with San Francisco, at the time of his bomb threats the Zodiac had already committed a crime as far from San Francisco as a nearly two-hour drive. Therefore, I feel it’s likely the Zodiac’s bomb would have been placed at a location somewhere within those two hours.

AND THE PERFECT SPOT FOR A DEATH MACHINE IS…

The city of Santa Rosa, Cal…for a variety of reasons.

Downtown Santa Rosa in 1970

Santa Rosa is located about an hour’s drive north of San Francisco, thus inside the Zodiac’s attack range. Additionally, the city of Santa Rosa had already seen its share of Zodiac-related activity, beginning in October 1969 with threatening phone calls to the local police station, as well as a bomb threat to a local department store…all made by someone claiming to be the Zodiac killer.

Additionally, the Zodiac killer was a suspect in a local series of (still unsolved) murders involving female hitchhikers.

Back then, Santa Rosa had a population of about 50,000. Much of the area was as rural as it gets, with buses transporting the students from their homes in the outlying areas and into the city proper where most of the schools were located. Highway 101 cut right through the city, which was primarily a valley with hills on the eastern outskirts.

The Zodiac’s list of bomb ingredients

When the Zodiac made his bomb threat — a bomb he claimed was already built and being stored in a basement — top suspect Arthur Leigh Allen occupied both his trailer in Santa Rosa, as well as the lower portion of his parents’ home about an hour away at 32 Fresno Street in Vallejo. Around the corner from the Fresno Street address was an Ace Hardware store where Allen would eventually work. The store not only had a basement, but it also sold all the necessary materials required to make the bomb exactly as described by the Zodiac killer. And when Allen’s home on Fresno Street was eventually searched by police, bomb-making materials were found inside.

The entrance to the old Ace Hardware in Vallejo. The store was demolished several years ago

Could the Zodiac killer have left behind an unexploded roadside bomb that wouldn’t be discovered for more than 45 years?

Fast-forward to Jan. 31, 2015, when a resident of Santa Rosa called police to report a suspicious device he had partially unearthed in his yard. The location was the 2500 block of Guerneville Road, about two and a half miles where the first two hitchhiker victims were last seen.

When police arrived at the Guerneville Road residence, they saw what was eventually confirmed to be an improvised explosive device measuring approximately 15 inches by 5 inches. Inside the device, 35 mm film canisters were visible, and wicks were seen sticking out of the top. The device was deteriorated and had been in the ground for so long that roots had grown all around it.

The Sonoma County Sheriff’s Department deployed its explosive ordinance disposal unit, and for safety purposes, the device was destroyed. Unfortunately, nothing more could be learned about the old, buried bomb.

News report, part one

News report, part two

Today, the 2500 block of Guerneville Road is a well-developed suburb. However, if you go back several decades to the Zodiac era, what is now someone’s backyard was open terrain right next to the road.

Amazingly, the bomb location fit perfectly with the necessary requirements that I outlined earlier.

Using an aerial photo from 1968, you can see the bomb location was very rural:

The area of the old, buried bomb as it appeared back in 1968

*Guerneville Road had school bus traffic that brought students from the boonies into the city proper and back again. However, there was obviously no need for public transportation. Therefore, school buses would have been the only vehicles of that height

*Guerneville Road was flat, straight, and oncoming traffic — what little there was — could have been spotted well in advance

*While the area has since been developed, the spot where the bomb was found — right next to Guerneville Road in what is now someone’s yard — was relatively untouched by progress

The bomb that was found in 2015 didn’t really match the bomb description provided by the Zodiac in his November 1969 threat letter. However, that could have been for any number of reasons…including the Zodiac not wanting police to know exactly what to look for.

It might be worth noting that from Arthur Leigh Allen’s trailer at 2963 Santa Rosa Ave., it was only a twelve-minute drive to the bomb site:

It might also be worth noting that one of those hitchhiker victims, Kim Allen, had been living on Guerneville Road at the time of her murder, and her home was just two blocks from where the bomb was found.

Had the Zodiac truly been giving us clues to his real identity, as he once claimed, perhaps the bomb location was another clue: A clue to the name Allen.

1996: My Hunt Begins

In my basement and reviewing several Zodiac suspects, including Arthur Leigh Allen

By Tom Voigt | Founder: Zodiackiller.com | tomvoigt@zodiackiller.com

I began collecting information about Zodiac suspect Arthur Leigh Allen soon after learning to navigate the Internet back in the mid-1990s. The process intensified in 1998 after launching my website, Zodiackiller.com. My research continues to this day.

In 1996, I was working in Portland, Ore. as a radio announcer for CBS. All was normal. Then one day, I got bit by the true-crime bug and became infatuated with the unsolved case of the Zodiac killer. Eventually, that infatuation put me on a path directly into the evidence rooms of three separate police departments, each bringing me inside because they felt I could help with the Zodiac investigation.

I’m not a cop. I don’t have a badge. I never studied criminology. In fact, I have no law enforcement background whatsoever. I was simply a private citizen desperate to learn more about the case of the Zodiac killer; I was certain it could be solved.

I began my Zodiac research by attempting to track down one of the key players in the case, a newspaper reporter named Paul Avery. In the 2007 film called “Zodiac,” directed by David Fincher, Avery was portrayed by actor Robert Downey Jr. Luckily, the real Paul Avery’s home telephone number was listed in a San Francisco phone book. So, I got up my nerve and gave him a call.

Paul Avery

As soon as I mentioned the Zodiac killer, Avery cussed me out and slammed down the phone. And there ended my attempt at investigating the Zodiac case…but only for about a week, at which point I had found enough nerve to call him back. And when I did, it was like night and day — Avery apologized profusely for the previous week’s phone call. He then proceeded to spend the next 30 minutes giving me insider case information, including the names of various Zodiac suspects previously withheld from the public. Avery then taught me about Arthur Leigh Allen.

With my newly acquired knowledge — thanks entirely to Paul Avery — I felt that I needed to share it online. However, most people I knew were like me and had never been on the Internet. Luckily, I managed to find a relative who taught me about computers, and I was off and running. The first search engine I used was called Netscape Navigator. Although social media didn’t exist in 1996, I still managed to make some valuable online connections almost immediately, including with a man named Bill who had a website called REDACTED.

A 1997 screenshot of Bill’s website

It turned out that Bill had contacts within the FBI. He also had a strong interest in the Zodiac case. I e-mailed Bill some of the secret information I had learned from Paul Avery, including the names of various Zodiac suspects. And within 24 hours, thanks to Bill and his FBI contacts, I had acquired a digital mugshot of Arthur Leigh Allen. Allen’s picture had never been published anywhere, and people had long wondered if the top Zodiac suspect looked like the sketch of the Zodiac killer. Even when Allen did some TV interviews in 1991, his face was blurred. So, I knew I had struck gold with his mugshot.

Soon after, I made online contact with Rob, a man whose father had been best friends with Allen and who had pages and pages of Allen’s handwriting. Luckily, Rob agreed to share with me a page of that handwriting, which also happened to be something the public had never seen. More gold.

Making my case against Allen

A very successful Zodiac book had portrayed Arthur Leigh Allen as likely being the Zodiac killer. However, the book hadn’t published Allen’s real name, or his picture, or his handwriting…three things that I had managed to acquire within just days of getting on the Internet for the very first time.

It was obvious to me that I should put Allen’s name, mugshot and handwriting on my own Zodiac website. However, I couldn’t afford to hire someone to build a website for me. And at that time on a computer, I could barely send an e-mail, let alone do anything more complex.

Somewhere along the way, I purchased a book that promised to make the website-building process an easy one. I gave the book a try and it worked! I created Zodiackiller.com all by myself and launched it onto the Internet on March 20, 1998.

How my website appeared in 1998. Originally called Zodiackiller.net, it quickly became Zodiackiller.com

Within six months of that launch, John Walsh mentioned Zodiackiller.com on his highly rated television show “America’s Most Wanted.” As a result, my site quickly became a favorite among true-crime enthusiasts, including a woman named Michelle McNamara, who went on to write an epic serial killer book titled “I’ll Be Gone in the Dark.” Michelle wasn’t shy about e-mailing me words of encouragement. In fact, even though she passed away in 2016, I still remember her old “mishmac” e-mail address and original online crime diary.

So yeah, I’m glad I called back Paul Avery. 

November 2025 Update:

In a very ironic twist, a few weeks ago I was contacted by an individual who had inherited many Zodiac-related materials which had been saved for decades by Paul Avery. Apparently, Avery’s goal was to pursue the many leads he had collected. Unfortunately, life had other ideas and Avery was soon overwhelmed with catastrophic health issues that plagued him for the rest of his life.

I now have access to those Zodiac materials, some of which look to be quite compelling.

Wherever Paul Avery’s information takes me, I will share what I can.

DNA and the Zodiac Killer: NEWS

The latest genetic testing yields mysterious results

By Tom Voigt | Founder | Zodiackiller.com | tomvoigt@zodiackiller.com

To the Vallejo Police Department, the desire to identify California’s still-at-large serial killer, the Zodiac, is as strong now as it was in the late 1960s, when the mysterious offender committed three area murders. Located about a 45-minute drive from San Francisco, modern-day Vallejo does not have an adequate police force, either in terms of budget or manpower. Still, it has been chasing the Zodiac for 57 years, and DNA is the last hope to catch him.

May 2018: In a story that made headlines across the globe, Vallejo police announced plans to genetically test items of evidence in an effort to obtain a DNA profile of the Zodiac killer. Then, in March 2019, Zodiackiller.com received an exclusive update on the testing process when it was announced that a genetic profile had been obtained from the submitted evidence. As a result, “The lab work has turned into more lab work,” the department said. “Vallejo PD is still at it. The hunt continues.”

And now, the latest — and exclusive — DNA update in the case of the Zodiac killer:

According to Vallejo police, the genetic profile that was previously obtained, belonged to an individual who could not have been the Zodiac killer. For privacy reasons, no other information was disclosed, adding to the mystery.

While the killer remains elusive — at least for the time being — “the hunt continues,” according to the Vallejo Police Department.
