|Titled "The Confession", the byline was reported followed by 12 or 19 underscores. Printed on a Royal Typewriter, a fingerprint was lifted from the envelope. It is still disputed whether it is the work of the killer.
Possibly a reproduction of the letter
- THE CONFESSION
SHE WAS YOUNG AND BEAUTIFUL BUT NOW SHE IS BATTERED AND DEAD. SHE IS NOT
THE FIRST AND SHE WILL NOT BE THE LAST I LAY AWAKE NIGHTS THINKING ABOUT MY
NEXT VICTIM. MAYBE SHE WILL BE THE BEAUTIFUL BLOND THAT BABYSITS NEAR THE
LITTLE STORE AND WALKS DOWN THE DARK ALLEY EACH EVENING ABOUT SEVEN. OR MAYBE
SHE WILL BE THE SHAPELY BLUE EYED BROWNETT THAT SAID NO WHEN I ASKED HER FOR
A DATE IN HIGH SCHOOL. BUT MAYBE IT WILL NOT BE EITHER. BUT I SHALL CUT
OFF HER FEMALE PARTS AND DEPOSIT THEM FOR THE WHOLE CITY TO SEE. SO DON'T MAKE
IT TO EASY FOR ME. KEEP YOUR SISTERS, DAUGHTERS, AND WIVES OFF THE STREETS
AND ALLEYS. MISS BATES WAS STUPID. SHE WENT TO THE SLAUGHTER LIKE A LAMB. SHE
DID NOT PUT UP A STRUGGLE. BUT I DID. IT WAS A BALL. I FIRST PULLED THE MIDDLE
WIRE FROM THE DISTRIBUTOR. THEN I WAITED FOR HER IN THE LIBRARY AND FOLLOWED
HER OUT AFTER ABOUT TWO MINUTS. THE BATTERY MUST HAVE BEEN ABOUT DEAD BY THEN.
I THEN OFFERED TO HELP. SHE WAS THEN VERY WILLING TO TALK TO ME. I TOLD HER
THAT MY CAR WAS DOWN THE STREET AND THAT I WOULD GIVE HER A LIFT HOME. WHEN WE
WERE AWAY FROM THE LIBRARY WALKING, I SAID IT WAS ABOUT TIME. SHE ASKED ME
"ABOUT TIME FOR WHAT". I SAID IT WAS ABOUT TIME FOR HER TO DIE. I GRABBED HER
AROUND THE NECK WITH MY HAND OVER HER MOUTH AND MY OTHER HAND WITH A SMALL
KNIFE AT HER THROAT. SHE WENT VERY WILLINGLY. HER BREAST FELT VERY WARM AND FIRM
UNDER MY HANDS, BUT ONLY ONE THING WAS ON MY MIND. MAKING HER PAY FOR THE
BRUSH OFFS THAT SHE HAD GIVEN ME DURING THE YEARS PRIOR. SHE DIED HARD. SHE
SQUIRMED AND SHOOK AS I CHOAKED HER, AND HER LIPS TWICHED. SHE LET OUT A SCREAM
ONCE AND I KICKED HER HEAD TO SHUT HER UP. I PLUNGED THE KNIFE INTO HER AND IT
BROKE. I THEN FINISHED THE JOB BY CUTTING HER THROAT. I AM NOT SICK. I AM
INSANE. BUT THAT WILL NOT STOP THE GAME. THIS LETTER SHOULD BE PUBLISHED FOR
ALL TO READ IT. IT JUST MIGHT SAVE THAT GIRL IN THE ALLEY. BUT THAT'S UP TO
YOU. IT WILL BE ON YOUR CONSCIENCE. NOT MINE. YES, I DID MAKE THAT CALL TO YOU
ALSO. IT WAS JUST A WARNING. BEWARE...I AM STALKING YOUR GIRLS NOW.

|Sent to the San Francisco Examiner, the FBI later determined these were written on Woolworth's "Fifth Avenue" brand paper, and contained fingerprints on the latter two pages
- Dear Editor
- This is the Zodiac speaking.
- In answer to your asking for more details about the good times I have had in Vallejo, I shall be very happy to supply even more material. By the way, are the police haveing a good time with the code? If not, tell them to cheer up; when they do crack it they will have me.
- On the 4th of July:
- I did not open the car door, The window was rolled down all ready. The boy was origionaly sitting in the front seat when I began fireing. When I fired the first shot at his head, he leaped backwards at the same time thus spoiling my aim. He ended up on the back seat then the floor in back thashing out very violently with his legs; thats how I shot him in the knee. I did not leave the cene of the killing with squealling tires + raceing engine as described in the Vallejo paper,. I drove away quite slowly so as not to draw attention to my car. The man who told the police that my car was brown was a negro about 40-45 rather shabbly dressed. I was at this phone booth haveing some fun with the Vallejo cops when he was walking by. When I hung the phone up the dam X@ thing began to ring & that drew his attention to me + my car.
- Last Christmass
- In that epasode the police were wondering as to how I could shoot + hit my victoms in the dark. They did not openly state this, but implied this by saying it was a well lit night + I could see the silowets on the horizon. Bullshit that area is srounded by high hills + trees. What I did was tape a small pencel flash light to the barrel of my gun. If you notice, in the center of the beam of light if you aim it at a wall or celling you will see a black or darck spot in the center of the circle of light about 3 to 6 inches across. When taped to a gun barrel, the bullet will strike exactly in the center of the black dot in the light. All I had to do was spray them as if it was a water hose; there was no need to use the gun sights. I was not happy to see that I did not get front page coverage.

|Sent to the San Francisco Chronicle following the killing of cabdriver Paul Stine, the letter included a piece of Stine's bloodstained shirt
This is the Zodiac speaking.
I am the murderer of the taxi driver over by Washington St + Maple St last night, to prove this here is a blood stained piece of his shirt. I am the same man who did in the people in the north bay area.
The S.F. Police could have caught me last night if they had searched the park properly instead of holding road races with their motorcicles seeing who could make the most noise. The car drivers should have just parked their cars and sat there quietly waiting for me to come out of cover.
School children make nice targets, I think I shall wipe out a school bus some morning. Just shoot out the front tire + then pick off the kiddies as they come bouncing out.

|"Death machine" letter sent to the San Francisco Chronicle
- This is the Zodiac speaking up to the end of Oct I have killed 7 people. I have
- grown rather angry with the police for their telling lies about me. So I shall
- change the way the collecting of slaves. I shall no longer announce to anyone.
- When I committ my murders, they shall look like routine robberies, killings of
- anger, + a few fake accidents, etc.
- The police shall never catch me, because I have been too clever for them.
- 1 I look like the description passed out only when I do my thing, the rest of
- the time I look entirle different. I shall not tell you what my descise
- consists of when I kill
- 2 As of yet I have left no fingerprints behind me contrary to what the police
- say in my killings I wear transparent fingertip guards. All it is is 2 coats of
- airplane cement coated on my fingertips -- quite unnoticible + very efective
- 3 my killing tools have been boughten through the mail order outfits before the
- ban went into efect. Except one & it was bought out of the state. So as you can
- see the police don't have much to work on. If you wonder why I was wipeing the
- cab down I was leaving fake clews for the police to run all over town with, as
- one might say, I gave the cops som bussy work to do to keep them happy. I enjoy
- needling the blue pigs. Hey blue pig I was in the park -- you were useing fire
- trucks to mask the sound of your cruzeing prowl cars. The dogs never came with
- in 2 blocks of me + they were to the west + there was only 2 groups of parking
- about 10 min apart then the motor cicles went by about 150 ft away going from
- south to north west
- p.s. 2 cops pulled a goof abot 3 min after I left the cab. I was walking down
- the hill to the park when this cop car pulled up + one of them called me over +
- asked if I saw anyone acting suspicious or strange in the last 5 to 10 min + I
- said yes there was this man who was runnig by waveing a gun & the cops peeled
- rubber + went around the corner as I directed them + I disappeared into the
- park a block + a half away never to be seen again. "must print in paper."
- Hey pig doesnt it rile you up to have your noze rubed in your booboos?
- If you cops think I'm going to take on a bus the way I stated I was, you
- deserve to have holes in your heads. Take one bag of ammonium nitrate
- fertilizer + 1 gal of stove oil & dump a few bags of gravel on top + then set
- the shit off + will positivily ventalate any thing that should be in the way of
- the blast.
- The death machine is all ready made. I would have sent you pictures but you
- would be nasty enough to trace them back to developer + then to me, so I shall
- describe my masterpiece to you. The nice part of it is all the parts can be
- bought on the open market with no questions asked.
- 1 bat. Pow clock -- will run for aprox 1 year
- 1 photoelectric switch
- 2 copper leaf springs
- 2 6V car bat
- 1 flash light bulb + reflector
- 1 mirror
- 2 18" cardboard tubes black with shoe polish inside + oute
- Bombs (1 bag each)
- 6V Bat
- 6V Bat
- bus goes bang car
- pass es by ok.
- the system checks out from one end to the other in my tests. What you do not
- know is whether the death machine is at the sight or whether it is being stored
- in my basement for future use. I think you do not have the manpower to stop
- this one by continually searching the road sides looking for this thing. + it
- wont do to re roat + re schedule the busses because the bomb can be adapted to
- new conditions.
- Have fun!! By the way it could be rather messy if you try to bluff me.
- PS. Be shure to print the part I marked out on page 3 or I shall do my thing.
- To prove that I am the Zodiac, Ask the Vallejo cop about my electric gun sight
- which I used to start my collecting of slaves.

The inside of the Christmas card
- Dear Melvin
- This is the Zodiac speaking I wish you a happy Christmass. The one thing I ask of you is this, please help me. I cannot reach out because of this thing in me won't let me. I am finding it extreamly dificult to keep in check I am afraid I will loose control again and take my nineth & posibly tenth victom. Please help me I am drownding. At the moment the children are safe from the bomb because it is so massive to dig in & the triger mech requires so much work to get it adjusted just right. But if I hold back too long from no nine I will loose
complet all controol of my self & set the bomb up. Please help me I can not remain in control for much longer.
April 20th 1970 
|(claims 10 victims) Sent to the San Francisco Chronicle, it claimed to contain a cipher containing the murderer's name, though it was never solved. (The 'blue meannies' (sic) mentioned in the letter is a reference to the blue meanies, the antagonists from the Beatles' animated theatrical film Yellow Submarine, which was released the year before.)
- This is the Zodiac speaking
- By the way have you cracked the last cipher I sent you?
- My name is --
- I am mildly cerous as to how much money you have on my head now. I hope you do not think that I was the one who wiped out that blue meannie with a bomb at the cop station. Even though I talked about killing school children with one. It just wouldn't doo to move in on someone else's teritory. But there is more glory in killing a cop than a cid because a cop can shoot back. I have killed ten people to date. It would have been a lot more except that my bus bomb was a dud. I was swamped out by the rain we had a while back.
- The new bomb is set up like this
(Text on the diagram)
- Sun light in early morning
- A B
- String of Bombs
- Car Bat
- A + B are photoelectric
- swiches when sun beam
- is broken A closes circut
- " " B opens "
- which makes B the
- cloudy day discon-
- -ect so the bomb
- won't go off by accid.

- I hope you enjoy your selves when I have my Blast.
- P.S. on back
- If you don't want me to have this blast you must do two things. 1 Tell everyone about the bus bomb with all the details. 2 I would like to see some nice Zodiac butons wandering about town. Every one else has these buttons like, , black power, Melvin eats bluber, etc. Well it would cheer me up considerably if I saw a lot of people wearing my buton. Please no nasty ones like Melvin's
June 26th 1970 
- This is the Zodiac speaking.
- I have become very upset with the people of San Fran Bay Area. They have not complied with my wishes for them to wear some nice buttons. I promised to punish them if they did not comply, by anilating a full School Buss. But now school is out for the summer, so I punished them in another way. I shot a man sitting in a parked car with a .38.

- This is the Zodiac speaking
- Being that you will not wear some nice buttons, how about wearing some nasty buttons. Or any type of buttons that you can think up. If you do not wear any type of buttons, I shall (on top of everything else) torture all 13 of my slaves that I have wateing for me in Paradice. Some I shall tie over ant hills and watch them scream + twich and squirm. Others shall have pine splinters driven under their nails + then burned. Others shall be placed in cages + fed salt beef untill they are gorged then I shall listen to their pleass for water and I shall laugh at them. Others will hang by their thumbs + burn in the sun then I will rub them down with deep heat to warm them up. Others I shall skin them alive + let them run around screaming. And all billiard players I shall have them play in a darkened dungen cell with crooked cues + Twisted Shoes. Yes I shall have great fun inflicting the most delicious of pain to my slaves

- As some day it may hapen that a victom must be found. I've got a little list. I've got a little list, of society offenders who might well be underground who would never be missed who would never be missed. There is the pestulentual nucences who whrite for autographs, all people who have flabby hands and irritating laughs. All children who are up in dates and implore you with im platt. All people who are shakeing hands shake hands like that. And all third persons who with unspoiling take thoes who insist. They'd none of them be missed. They'd none of them be missed. There's a banjo seranader and the others of his race and the piano orginast I got him on the list. All people who eat pepermint and phomphit in your face, they would never be missed They would never be missed And the Idiout who phraises with inthusastic tone of centuries but this and every country but his own. And the lady from the provences who dress like a guy who doesn't cry and the singurly abnormily the girl who never kissed. I don't think she would be missed Im shure she wouldn't be missed. And that nice impriest that is rather rife the judicial hummerest I've got him on the list. All funny fellows, commic men and clowns of private life. They'd none of them be missed. They'd none of them be missed. And uncompromising kind such as wachmacallit, thingmebob, and like wise, well - - nevermind, and tut tut tut tut, and whashisname, and you know who, but the task of filling up the blanks I rather leave up to you. But it really doesn't matter whom you place upon the list, for none of them be missed, none of them be missed.

- Like I have allways said, I am crack proof. If the Blue Meannies are evere going to catch me, they had best get off their fat asses + do something. Because the longer they fiddle + fart around, the more slaves I will collect for my after life. I do have to give them credit for stumbling across my riverside activity, but they are only finding the easy ones, there are a hell of a lot more down there. The reason I'm writing to the Times is this, They don't bury me on the back pages like some of the others.
