The knife has very low amounts of LCN DNA which Stefanoni kept over-riding the machine limits of too low too low. This was a very minute amount of DNA on this knife
The bra was collected 47 days after and here is an interview with an expert regarding both of these. I hope it helps you
Italy is the one of the only European countries that has not signed on to the Prum Convention, which establishes protocols and certification standards for DNA testing. Italy has no labs that meet the certification requirements applied throughout the rest of western europe
Italy's inability to meet certification requirements and continuing refusal to sign on to the convention have been topics of discussion within the EU for some time
These are only 9 of noted errors specific only to the LCN DNA
nine distinct ways Stefanoni's improv LCN DNA profiling was even worse than unproven and inadmissible LCN DNA profiling tests.
1. The DNA wasn't amplified enough; the very weak fluorescence was simply blown up.
2. The test site was not remote from other DNA tests to avoid contamination.
3. Specialized LCN-quality entry procedures to avoid contamination were not used.
4. A positive pressure environment was not maintained to exclude contamination.
5. Special LCN sterilization procedures to destroy errant DNA were not used.
6. The entire sample was consumed in a single test; no comparison of tests was possible.
7. No sample was retained for future reference. The test can never be reproduced.
8. No negative control tests were run to check for contamination.
9. No control tests to check for field contamination were performed
