The failure to produce the EDFs is bad, but in my opinion, there is another issue that is even worse.
Stefanoni has selectively produced amplification and egram records. We can tell from the gaps in the records, that from within these two categories of records, she has produced the records that make her look good and has withheld the records that could cast question upon the validity of her results.
We have amplification records for run nos. 543-544, and then a gap until 549. The gap records, 545 to 548, correspond to the period 11/12 to about 11/25, during which time the LCN work was done and the kitchen knife samples were identifed. In other words, these are the most important amplification records in the case.
Similarly, although we have a bates-stamped collection of egram records, we can see very clearly that there are missing records from within the egram collection produced by Stefanoni. Notably, the particular run in which 36b was analyzed has the highest number of "missing" egrams. The circumstances of the missing egrams suggest to me that they likely show indeterminite mixtures of DNA, which likely would support a contamination argument, but this argument can't be made because the records have been withheld.
The two examples above are not as simple as Stefanoni not producing the EDFs because she "had no idea" that the defendants needed them; rather, this is a kind of selective production and withholding of exculpatory information. In other words, it's deceit, aka prosecutorial misconduct.
