The mistake is assuming that every spot in the cottage was tested for DNA. But in fact, only a limited number of spots were tested. We know Raffaele's DNA would likely be found on the doorknob to Meredith's room, but that spot was never swabbed for DNA.

Same goes for Knox's DNA not being found in the murder room. Right? Why would Sollecito leave DNA on the door or doorknob? These are smooth surfaces. That is not so likely at all.

why would he leave dna on the doorknob? raffaele tried to open/break down the door! and, yes, quite likely:

Police said they also found Durdek’s DNA on a doorknob to the main door of the building.

Skinner's DNA was also found on door knobs – both inside and outside the house – and on the back door of the house.

Lab tests showed that the boy's father -- Biela -- was almost certainly a match for the DNA found on the doorknob and at the crime scene, police said.

The turning point came when investigators submitted DNA found on a beer can and doorknob for comparison with DNA samples logged in the FBI's Combined DNA Index System.

Assistant District Attorney Stacey Okun-Weise's case relied on DNA found on Redding, her cellphone, the doorknob, and on a knob on the stove.

BBM. Because he says so? Or is a fingerprint now proof of 'breaking the door down'. The links have no meaning as it is not about the possibility of leaving DNA on a door knob. It is about the probability.

Who was the last person to touch the door handle? Was it Filomina's friend? Was it one of the Postal Police?

If you are vigorously pulling and/or pushing on the door handle trying to open a locked door I could easily see where you would deposit finger prints and DNA on even a smooth handle (by the way, are you sure the handle to Meredith's room is smooth (I honestly don't know)).

Surely the people that pushed and pulled on the door handle, after Sollecito touched the handle, were successful in wiping all DNA off the door handle.

A more likely result is contributing some of their own DNA. Which may be the reason why DNA from at least three other unknown males was found on the bra clasp.

Maybe so, but it is an assumption that he even did that. I just thought it is a bit easy to imply that whenever you touch a door you leave DNA. Besides you still need a tertiary DNA transfer theory to transport his DNA to the bra clasp. Tertiary DNA transfer has a probability of about 0%.

There were only 2 major contributors to the mixed DNA sample on the bra clasp.

A bra clasp that was handled badly and kicked all over the floor before it was found some time later...

 

[sherlockh]

If the theory is that it was contaminated with DNA from the door then the 'moving of the bra clasp' and 'left for 43 days' are irrelevant.

i gave FIVE examples (using only the first two pages of bing search for "dna found doorknob") that it is easy to leave dna just by touching a door, which disputes at least one assertion in your link. as for "tertiary dna transfer has a probability of about 0%":

Sufficient quantities of DNA were obtained via secondary and tertiary transfer. DNA profiles could be observed from an individual to an object even though that individual did not directly touch the object.

Someone leaving his DNA on a doorknob is not tertiary DNA transfer. Sorry, but again the link does not have anything to do with the issue here which is about probability. I don't recall this theory being part of the Nencini appeal.

 

[otto]

The doorknob contamination theory seems like a funny theory. Perhaps I'm misunderstanding, but this is what I understand:

Meredith touched the doorknob for her bedroom.
Knox touched the doorknob for Meredith's bedroom.
Sollecito touched the doorknob for Meredith's bedroom.
Filomina's friends touched the same doorknob after Sollecito.
Postal police touched the same doorknob after Sollecito.
No prints or DNA could be obtained from the doorknob, or none were taken.

Sollecito's DNA may have remained on the door knob.
Investigators may have put on gloves while the door was closed and may have touched the doorknob.
At some point, investigators that touched the doorknob may have touched the bra, allowing only Sollecito's DNA to attach to the bra.

Did I miss anything?

 

[Amber29]

All this talk of transferring DNA from a doorknob to a key piece of evidence has me wondering how many other convicted criminals could use this excuse. Although I guess many do use "contamination" as it is, however unbelievable as it may be.

News of the prosecutions flawed and supressed evidence is spreading.

Experts: Flawed DNA evidence used against Amanda Knox

http://www.komonews.com/news/local/...t-Amanda-Knox-seriously-flawed-261708911.html

The presentation by experts Greg Hampikian and Tom Zupancic focused on errors made in collecting DNA at the crime scene that compromised the investigation and may have caused police to reach erroneous conclusions or allowed the evidence to be manipulated.

snip

American attorneys ... were stunned to hear how the Italian forensic analysts and prosecutors connected to the Knox-Sollecito case manipulated and withheld evidence in this case," he said. "Such behavior would never have been tolerated in the American system. It shows an inherent contempt for fairness, the concept of justice and is a serious breach of acceptable judicial practices.”

 

[MichaelSmith]

The only evidence collected from the cottage containing a sample of his DNA (mixed with Knox's)was found on a cigarette butt in the kitchen (i may be mistaken but from what I can see this was taken into evidence sometime 2-4th) The bra clasp was found 43 days after the murder happened, in a sealed crime scene.

I don't think it could happen how you said above, because they were collected at different times. Although I am still trying to learn about this so correct me if I am wrong.

What are the ways that the DNA can be transferred from the cigarette butt, that was collected over 40 days earlier onto the bra clasp?

You mention dirty gloves, so does this mean that someone would have to have handled the cig, took the gloves off, saved them and put them back on to handle the bra clasp.

Is another possiblity is someone could have touched the bra clasp on the day the cig was found, then pretended that it wasn't there and none of the technicians had seen it?

Also at this point, I am assuming they had no idea that the DNA on the cig belonged to him, so the above theory makes no sense. What are the other possibilities?

Also the DNA was mixed with Amandas so would hers not show up to?

http://themurderofmeredithkercher.com/The_Bra_Clasp#Tertiary_Transfer

There was no DNA mapping done. It's not like they tested every inch of the entire cottage.

What they tested and when is listed here. http://www.injusticeinperugia.org/test_results_index_translated.doc

I don't believe I recognize either of those names as people that were qualified as experts in this murder trial.

 

[Footwarrior]

Isn't Steve Moore the man that started rumors about Guede being an undercover agent that was released by police in Milan only because police in Perugia told them to release him? Has he presented any factual evidence to support this opinion? If not, I think the logical flaws could be as far fetched as his beliefs about Guede.

A classic example of the logical fallacy known as "poisoning the well".

Who poisoned the well? Was it the lies of Amanda Knox, or the interpretation of the broken window evidence as a staged break-in? Even though the staged break-in could be an error in judgement, why did Amanda Knox lie about everything from her timeline to who was with her at the time of the murder.
