KE: Do you believe the investigators made mistakes that subsequently diverted the course of the investigation?
JD: Well, that’s the entire story, isn’t it? First, there were too many people in those rooms. They should have removed Amanda, Raffaele and anyone who was not part of the investigation team, and roped it off.
From the video taken from the crime scene, there were numerous mistakes. The investigators can be seen passing evidence, dropping it on the ground, using the same tweezers, not changing gloves, no protective caps to cover hair. Any insider can recognize these errors. What the investigators have done may seem right on the "outside", they had their protective clothing, boots, but cross- contamination of the evidence was more than evident.
KE: What is cross-contamination, exactly?
JD: It means simply that evidence from anyone, anyone who came and went in those rooms have the potential to leave their DNA, prints, etc. and run the risk of being transferred microscopically.
