FBI files (No1 page 53):
"Inspector Toschi advised that investigation is currently being conducted by Napa, Vallejo and San Francisco Police Departments concerning captioned matter and that he believes UNSUB may have military background in as much UNSUB used bayonet and two separate 9mm weapons and one of surviving victims observed UNSUB to be wearing military type boots. Further Inspector Toschi related that the enclosed letter from UNSUB (Oct 13th letter), identifying himself as Zodiac and stating he was responsible for the killing of cab driver, enclosed a blood stained piece of material alleged to have been taken from victim’s shirt. Toschi stated he had definitely established that material did in fact come from victim’s shirt and laboratory examination indicated handwriting IS SAME AS THAT IN PRIOR LETTERS WRITTEN IN NAPA COUNTY ON 9/27/69."
"The enclosed letter (Oct 13th letter) and envelope are being furnished to the laboratory for examination and comparison with material previously submitted by Sacramento division in this matter.
Copies of the letter and envelope and wanted flyers are being furnished to Sacramento Division for information and any action deemed advisable."
Either this is correct or two mistakes are present; ie they never meant Napa County and they never meant 9/27/69, which seems highly unlikely. But my translation of this report is "and laboratory examination of the handwriting of the October 13th Stine letter, is that it matches handwriting from the Napa County letters of September 27th 1969." If they withheld "by knife", it is equally believable they withheld letters sent by Zodiac to validate this crime. They even withheld the Little List letter for over 2 months. Maybe after Zodiac committed the taxicab murder on October 11th 1969, the will or need to release these letters diminished.
It’s certainly possible that there are genuine Z letters out there we don’t know about for one reason or another. The famous DMV letter springs to mind. But the latter is, well, famous: I can’t help but think that if there was a post-LB letter out there, we’d at least have plenty of rumors about its existence.
Morrill confirmed that the car door writing was done by Z. That could be what this refers to. "Letter" is in fact the car door.
They may have inadvertently wrote letters instead of car door,where they could have simply stated the writing is the same in both cases

Yah, maybe like "letters" on the car door…like, alphabetical letters.
“…they may be dealing with one or more ersatz Zodiacs–other psychotics eager to get into the act, or perhaps even other murderers eager to lay their crimes at the real Zodiac’s doorstep.“ L.A. Times, 1969
