Not directly, but indirectly they admitted even at trial that bones were moved. Their theory at the time was that they were moved by Avery FROM his burn pit TO his sister's burn barrel. From Kratz's closing argument:
http://www.stevenaverycase.org/wp-c...Trial-Transcript-Day-24-2007Mar15.pdf#page=54
"Bones were moved in this case. There's
no question of that. Who moved the bones, to the
State, or for the theory of the prosecution is
easy. Mr. Avery moved the bones. He moved the
big bones. He moved the big bones, the ones he
could identify as human bones, from his burn pit,
over to his sister's burn barrel. All right.
That's a couple hundred feet away."
And later about the quarry bones:
"17 The bones were moved, but they were
18 moved by Mr. Avery. These bones in the quarry,
19 I'm going to take about 20 seconds to talk about,
20 because the best anybody can say is that they are
21 possible human. What does possible human mean?
22 Well, it means we don't know what it is. "
So at trial the State was trying to argue the bones in the quarry should not even be considered evidence as he goes on after this to say "whether they are human or not, could not, even by the FBI, be determined. "
However, in Zellner's latest brief she correctly IMO argues that the State implies those bones were not only human but also Theresa Halbach's by giving them to her family. I already posted this and it can be easily read in her latest brief so I'm not going to post a link to it again.
This would make it harder for the State to try and argue that the burn pit was the only burn site, so I highly doubt they will do that if in fact there is a new trial or even evidentiary hearing. Doesn't mean they won't though.
My issue with Samson's post though is the creation of a strawman, actually two, in order to make it easier to refute the case against Avery.
