I expect the forensic team reasoned it had to make a decision where best to deploy its expertise. Outside in the hallway where Knox and Sollecito had deliberately let all and sundry trample about before the door was broken down would not have yielded any useful information for the purposes of hard evidence. Now the murder room itself had had just Batistelli, the police officer who was confronted with the scene and the medical/forensic/detective staff.
Raff was not in the room to place his DNA on the bra clasp when the body was discovered, as Knox and he knew it would be.
So here is an actual review of the literature on DNA transfer by actual professional scientists:
https://www.sciencedirect.com/science/article/abs/pii/S1872497318303958
They refer to how DNA transfer is like ketchup, so rather than testing actual DNA transfer they just throw ketchup on everything and roll around in it like a bunch of idiots.
Just kidding, they don't actually do that. Sorry Vixen. Thought you may have had a point there for a second.
This story was published five years ago but it's completely relevant to this discussion; https://www.mercurynews.com/2014/06/28/monte-sereno-murder-case-casts-doubts-on-dna-evidence/
So ignorant. There were DNA fragments that are found in dust (aka background contamination) and are not legally recognised as authentic. For DNA to be recognised in a court of law it needs to be a very strong 10-alleles at the minimum. Raff's DNA on the bra clasp where someone had forced it out of shape is a full house of 17 alleles.
This is as clear a piece of hard evidence as is a fingerprint on a gun.
NO ONE is claiming it was not Raffaele's DNA so stop harping on that as if you're making some relevant point. You're not. It's HOW it got there that was in dispute. Why is that so difficult for you to comprehend?
So ignorant. Even Peter Gill states that secondary transfer is unlikely to happen after 24 hours. Why? because the organic material that contains the DNA (greasy sweat, blood, saliva) has an unfortunate tendency to completely dry up within an hour or less.
You are ignorantly claiming that a casual imprint of Sollecito's hand on the door some six weeks ago (and the delay was deliberately engineered by the defence) has been transferred by tertiary transfer .
Your lack of education in fundamental biology is beyond amusing. Fancy believing a new latex glove from a new box will cultivate Raff's 100% solid DNA and transfer it self to a metal bra clasp. Stefanoni never even touched the door.
The onus is on you to demonstrate that DNA jumps around like a flea on dog's backside.
Video evidence demonstrated that the officers did not follow proper procedures with respect to the handling of this item, e.g., they used non-sterile gloves, did not change gloves after touching a surface or item, passed the clasp around, and dropped it on the floor. The failure to adopt these measures was significant because Sollecito had frequented the apartment and had attempted to open the door to Kercher’s bedroom prior to the discovery of her body on November 2nd, 2007. This could have been a source of contamination. There was no attempt made to take samples from the outer door handle. Gloves have been shown to be excellent intermediary substrates to transfer low levels of DNA from one object to another
The method of collecting, handling, transporting, and analyzing the bra clasp did not conform with basic protocols to minimize risks of cross-contamination. There were numerous opportunities in this process for cross-transfer and contamination of the clasp.
https://www.fsigenetics.com/article/S1872-4973(16)30033-3/fulltext#sec0080In light of the 46-day delay in collecting the clasp, the presence of profiles of other individuals in the sample (as discussed in the next section), and the failure to follow basic standard protocols for the collection and storage of the clasp, the evidence was irreversibly compromised. Consequently, the most likely explanation for the presence of Sollecito’s DNA is that it resulted from a contamination event, although the specific route cannot be discovered.
Your need to resort to childish hyperbole and false accusations as seen in the last two paragraphs does not make your argument stronger. It merely reveals your own ignorance and desperation.
Let's take a look at what Prof. Gill actually said regarding the DNA on the clasp:
https://www.fsigenetics.com/article/S1872-4973(16)30033-3/fulltext#sec0080
Vixen, you appear to consider yourself to be more knowledgeable about DNA and contamination than Prof. Gill. On what exactly do you base that? Is it your years of academic training in forensics? Is it your years of actual hands on experience? Is it your various peer-reviewed articles?
Vixen is just strawmanning here and has been for 12 years. She can't address the actual argument (it was transferred indirectly due to poor evidence collection procedures; proven by actual video evidence), so she makes up an entirely different argument that no one is saying and spends 10+ turbo posts spouting nonsense. But it's Vixen so hey
She's an expert in the physics of ketchup transfer?
The link is behind a pay wall. Can you please quote relevant parts or summarize for us?
Yes. She has a doctorate in Ketchup Management from Heinz University.

There is zero evidence the glove is dirty. That speck on the video could be a trick of light, a pixel, a crease, a shadow, graininess of the film. It is absolute bollocks to claim it contains Raff's DNA when he had never even been in the room (or so he claims).

The clasp was perhaps trodden on or, in any case, moved (such that it was found on the floor in a different position from where it had initially been noticed). Not only this, but the photographic documentation produced by Sollecito’s defence demonstrates that, at the time of the collection, the clasp was passed from hand to hand by the agents, who in addition were wearing dirty latex gloves.”
Gill never saw the evidence first hand. He is merely riding on the back of the crooked Conti & Vecchiotti, who didn't even have a fridge thermometer in their labs, bodies piled high in the corridors and Veccchiotti fined €150K for refusing to test the DNA of a murderer for nine years.
From the article...
"In the pivotal case, Anderson was arrested on murder charges after his DNA was found under the fingernail of Silicon Valley millionaire Ravi Kumra, who suffocated after thieves bound him during a 2012 home-invasion robbery at his gated Monte Sereno estate.
Despite the DNA, nagging concerns about the case persisted. The prosecution saw connections to support the DNA link — that Anderson had a residential burglary conviction on a criminal rap sheet composed otherwise of nonviolent minor crimes such as being drunk in public, and he had spent time in the same jail dorm with a member of one of the gangs tied to the Kumra killing. But that gang member wasn’t implicated in the murder. And while the others accused in the homicide belong to some of Oakland’s most violent home-invasion gangs, Anderson didn’t seem mentally capable of organized crime. He suffered a brain injury from being hit by a truck and could not even recall his whereabouts that November night.
Kulick pursued every avenue to prove Anderson had nothing to do with the crime, eventually discovering medical records that show on the night Kumra died, Anderson was at Santa Clara Valley Medical Center, where he had been taken by ambulance after passing out drunk in downtown San Jose.
His DNA turned up at the murder scene only because paramedics inadvertently transferred it there, via a simple oxygen-monitoring probe they’d clipped first onto his finger and then onto the dead man’s. Prosecutors dropped the charges after examining a dossier Kulick put together, interviewing the paramedics and hospital personnel, and reviewing videotape of the crime scene to make sure the paramedics had really treated both men. Anderson walked out of jail five months later."
