You mean the memo that only clearly references secondary transfer when it states:
With respect to secondary transfer, peaks above background (15-20 RFU) from the second individual were not detected for most STR amplifications. On occasions minor peaks (below 75 RFU from the second individual were observed.
However in these instances, allelic dropout was routine. The complete secondary profile was never detected, even if the data were analyzed in the 50/75 RFU range.
Interestingly...the memo includes a study involving the testing of single cells where it was found:
We amplified DNA in 91% cells, containing a full DNA profile in 50% and an acceptable profile (four or more STRs) in (64% of these cells).
These results show great promise and could be applied, for example, to smudged fingerprints, single flakes of dandruff, single sperm in multiple rape cases, and small samples left on weapons or vehicles.
So, Charlie, I think this memo does not state what I think you think it does. This memo actually rather proves that Raffaele needed direct transfer to the clasp for his DNA profile to have been found in the strength it was found. The memo also includes reference to a study showing the viability of DNA profiles from single cells.
In other words: Charlie, this memo shows you're wrong about secondary transfer of Raffaele's DNA to the clasp. This memo also shows Halides1 is very probably wrong when he claims that the knife DNA doesn't match Meredith's DNA (or that there wasn't enough DNA material for a match...or that the results aren't a match...I'm not quite sure what he's claiming this week).
