It seems as though she took in a lot of money (hundreds of thousands) and samples. It is very likely that she ran at least a few samples by screening tests that her lab could perform, and that she had at least a few tests (that her lab could not do) run by other labs. The exact makeup of the testing is unclear although it involved sequencing of mtDNA for some samples and some nuclear DNA genes for some samples.
"Interesting" can mean many different things. Firstly, known non-human animal DNA is not very interesting so lets dispense with those samples. Let's just discuss the "primate" DNA.
Every human being (except identical siblings) has unique DNA. Very few, relatively, are in GenBank. Does that make DNA results of most every human being "interesting" ? Well, yes, if it is your own DNA; but specifically in the "bigfoot" sense, no.
It is apparent that the late Richard Stubstad convinced her that at least a few of these mtDNA results were "interesting," in the bigfoot sense, in large part because they were not identical to any sequences in GenBank. There was a lot of balderdash about "Eves" and Iberian glacial refuges and SNP's in nuclear genes etc, but it seems that these were just a lot of shiny objects. She has never shown anything that isn't human and never said she has anything that isn't human, and specifically ruled out a hybrid from her results as of 2010. Furthermore, she has not described any consistent DNA findings from one specimen to the next that would indicate a close relationship between individuals. While she may have found all this to be "interesting" in the bigfoot sense, I don't think that any journal would find it interesting, unless it were written as a "negative for the supposed bigfoot" paper. She has not indicated that she was writing a negative paper.
What results obtained after 2010 she might have, we just don't know. She has supposedly (see below) written that the 2010 summary of her data has been withdrawn.
As far as we know, she has no legal constraints on publishing whatever she has found.
There is no proof that she has ever submitted an article for publication, let alone that it has been accepted. As far as I know, there is no proof that she has never claimed that it was submitted. Matt Moneymaker has claimed that she submitted a paper, and it was "handed back" ie rejected. MM may have access to the person who was funding Ketchum's work, so his statement has to be considered as possibly true.
We actually know very little else; a lot of stuff was posted on Facebook, but my impression is that at least one other person had the ability to post there. I have a suspicion that this other person may not have always identified herself when posting, thus making her posts appear to have been written by Ketchum. Some people claim to have communications from Ketchum but there is no significant documentation that has been made public, that I am aware of.
