I used to believe "brownett" in the ‘Confession’ letter was a misspelling of brunette, and I was wrong. It actually was referring to brownette. According to Google searches this is an antiquated concept, but distinctions used to be made between raven-haired, dark-eyed beauties and their lighter counterparts. Apparently even in its heyday (Max Factor coined brownette in the late twenties) the term was controversial. Brownette is a person of intermediate coloring usually with rather light brown hair, skin fairer than olive, and eyes of blue, gray, or green. The author of the ‘Confession’ letter correctly tied "brownette" with "blue eyed."
"The brownette is one whose natural complexion and coiffure tints actually should be placed in a range definitely in between the blonde and brunette degrees of coloring—and statistics prove that forty-eight per cent of the world’s women come under this brownette classification." https://www.theparisreview.org/blog/201 … p-forever/
If the ‘Confession’ letter was authored by the killer, as he led us to believe, and was relatively young, either Cheri’s age or in their early 20’s, would he be aware of distinctions such as brunette or brownette, and be able to tie in eye color. It’s certainly something I was unaware of until today. This coupled with references such as "little store" and "babysitting" makes me question the identity of this author more than ever. Was brownette something that was in common usage in 1960’s America by relatively young males.
Toy dolls were sold with such distinctions.
We have a killer who plays with toy dolls Druzer- This guy is a real sicko.
The guy was into barbies, no question. The only places I can think of where brownette would be in common usage are toy stores, hair salons, and newspaper columns about makeup. Oh yeah, we are definitely closing in here.
We talked about this a little bit here: viewtopic.php?f=79&t=71&p=33943&hilit=brownette#p33943
We know the reproduction used "brownett", but the original (as typed by the DOJ–which I’m not fond of that report as missed some words in that letter as well) used "brunette". The word itself (while it’s hard to see the actual word) doesn’t appear to end in an "e" though…more reason not to trust the DOJ. 
“…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
Thanks for the link Tahoe. I have never heard anyone utter this word in my life. I found it unusual to be used by a supposed male killer, during a ‘murder confession’.
I, too, have never heard the term, "brownett". Perhaps the CONFESSION author meant brunette, but was unsure of the spelling and opted for a simpler version. Today, I think "brunette" refers to brown-haired fems and "black-haired" to the black-haired. Much ado about little, eh?
Google Books shows how the popularity of the term "brownette" has changed over time within their scans of many thousands of books:
They don’t have data for "brownett" because it did not appear in enough samples.
In other words Dave it’s beyond rare. It’s almost never used. 
To give an idea of the relative rarity of the word, here is the raw data from their plot. First column is the word, second column is the year, third column is the number of appearances of that word in the scanned books, and the fourth column is the number of different books the word appeared in:

I believe this comes from about 5 million books that Google scanned up to the year 2008.
Example words that were about as rare as "brownette" are "bodacious", "brainlessly", "bibbling", and "buckeroo":
The idea that a male of relatively young age would use this word is therefore almost unheard of. He certainly wasn’t attempting to write brunette. Getting the respective eye color correct, as mentioned above, combined with phrases used in the Confession letter, what odds on the author being a woman. I don’t subscribe to this, but neither rule it totally out.
Elements of the letter have a style of femininity. A letter, not unlike the JonBenet Ramsey case, where the author uses words and sentences I personally wouldn’t attribute to a male, including ‘brownette’ and ‘little store’. It is almost over descriptive.
