Continuation - Discussion of the Amanda Knox case

Status
Not open for further replies.
Did her family say this before, or after they were trying to get her off a murder charge?

Do you suppose they made it up so far in advance because they knew Treehorn (or anyone) would be trying to make the case she couldn't be bullied into an internalized false 'confession?'

Besides, we already know it was a false 'confession.' Doesn't that kinda corroborate their statement to a certain extent? :)
 
Aren't lie detector tests more than a little pseudo-scientific? If Amanda had failed one, would we be hearing how she was tired, she was stressed, she didn't understand the question etc. etc. etc.....? What would one prove?

I think they need to be 'interviewed' by honest cops.

I nominate Steve Moore and John Douglas.
 
Presumably at trillioniths of a gram, or pico grams, it isn't much of a mixture. It may not even be a complete cell.
Quite. If, say, one is selecting 3 cells out of a total of 10 to do a blood test on, and there are an equal number of flesh and red blood cells in the sample picked with equal probability, then the odds of chosing all flesh cells for your blood test are, I think, a little under 10%.

No, but they are hardly going to go around saying to people "Please believe us that Amanda is innocent, but we should point out that we always worried that she'd get involved in something like this, such a reckless, selfish creature!", now are they?

No.

Anybody know what the estimated weight of the material was? I've heard that the original estimate of 100 trillionths of a gram (100 pico grams) was an exaggeration of the weight of the material. I've also seen that the weight of a human DNA molecule was calculated at 6 pico grams or 6 trillionths of a gram.

Expanding on my earlier post.

From http://encyclopedia.thefreedictionary.com/White+blood+cell

There are 10g of white blood cells per liter of blood. One liter of water weighs 1000 g and we float, so I'm estimating that one liter of blood also weighs about 1000g. 1% of that weight is the weight of the white cells - 10g.

There are ten billion white blood cells per liter (ten to the tenth). Consequently, the average white blood cell weighs a billionth of a gram or 1000 pico grams. The weight of one DNA molecule is 6 pico grams.

This reminds me that I saw on PMF during my recent visit to the wall of beautiful cats, that they mentioned an article that Rocco has requested that Amanda's picture be removed from that wall of shame.

Halfway there! :D

I can just imagine what they had to say about Rocco...
 
Except of course they found it before they arrested him, and for that matter before they knew who he was, not long afterward.
Come now! Again, everybody elses imaginations seem to suddenly fail them. Swap a sample here, open an evidence bag there.... how hard would it have been? In any case, they knew Rudy was a local with a history of burglary. Perhaps they just figured they'd frame him and get him out of their hair as well. Amanda blaming Patrick wasn't part of the plan.

We know from Frank that Rudy was responsible for all the burglaries in Perugia above the ground floor, so many the police were sick of him?

No.

Why not? What do you think happened in that police station that night? What do you think it means now?

She could have made a false confession/accusation for all sorts of reasons. She could be the sort of person who lies to try to get themselves out trouble, for example. Her family are hardly going to be telling people about that, are they? "Oh, Amanda! The stories we could tell about all the lies she's told to try and avoid getting the blame for things. Why, one time she took my purse and blamed it on our neighbours son. I was on the point of going next door to complain when I thought to check her room. Now where was I..... oh yes, how the police forced a false confession out of a poor honours student."

Did Amanda 'borrow' a knife from Meredith's apartment to bring to Raffaele's when she needed to cook for him? Maybe Amands's only crime was to steal a knife before the murder. She wouldn't admit to even that, though.

A few controls were needed. How much DNA did the lab find on other eating instruments in the drawer? How many DNA molecules were found? Way too many variables and unknowns!

To make a long story short, the preponderence of evidence rules against the knife being the murder weapon. The knife was only one of a chain of suppositions that need to be proved to conclude that Amanda & Raf are guilty. The scientific community would NEVER conclude that Amanda & Raf are guilty.

They were looking for Rudy because they found all that evidence of him at the scene.


Police are looking for a fourth person in addition to Knox, Sollecito and Diya "Patrick" Lumumba, a Congolese bar owner and musician. The fourth person is believed to be a North African man.

If that were the case I imagine they would have just arrested him when he was caught red-handed a couple times previous to the murder.

Had they done so, Meredith would still be alive. I doubt they'd want to frame the man they had let go, making them in some sense partially culpable in the death of Meredith Kercher. Even if it was actually physically possible, with him having left the country and all.

Do you suppose they made a cast of his finger to make the bloody fingerprint? :)
 
Amanda reported that her two Italian roommates "smoke like chimneys," meaning they smoke cigarettes. It's doubtful Amanda was going to write about smoking pot on her Myspace page.

If you want Meredith's DNA to be on Amanda's fingers and then on Raffaele's knife, you are going to have to have Amanda not touching anything else between the time she shares the joint with Meredith and the time she gets to Raffaele's to cook. You are also going to have to have her rubbing her finger into just the right section of the knife in order to embed Meredith's DNA in the minuscule crevice. And of course, you are going to have to eliminate the washing with bleach.
___________________________

Umm, Mary, smoking cigarettes "like chimneys" makes no sense at all. Amanda was citing the multiple attractive features of her new found residence. As a non-smoker Amanda would not have found her flatmates smoking tobacco "like chimneys" appealing at all. Instead, disgusting.

And she could have touched multiple items before touching the knife, and still have had Meredith's DNA on her fingers.

If that were the case, why did she 'lie' herself into getting arrested? That doesn't make any sense, her sinister plot was to put herself in a cage?

It's a pity for her that she didn't. There might afterall have been some hope that the other housemates would confirm that the knife had come from the appartment where the murder took place.

A few controls were needed. How much DNA did the lab find on other eating instruments in the drawer? How many DNA molecules were found? Way too many variables and unknowns!
I can't see a scenario where there is Meredith's DNA on the teaspoons and so on on the drawer. We keep talking about this, and I'm not sure that anyone has ever shown that it is standard procedure to take random objects along with whatever item of interest is taken into custody.

To make a long story short, the preponderence of evidence rules against the knife being the murder weapon. The knife was only one of a chain of suppositions that need to be proved to conclude that Amanda & Raf are guilty. The scientific community would NEVER conclude that Amanda & Raf are guilty.
No, the knife is not necessary for them to be guilty. This is also not a question of the scientific community concluding things. Science generally occurres in controlled environments, or experiments are repeated in order to control for the varguaries of environment. One does not necessarily have that luxory in real world situations.

Ms. Nadeau made this point some time ago

The forensics as regarding RG were, nevertheless, never disputed on this site.

On the other hand, those pertaining to the lovebirds are still being disputed; in the minds of many posters on this site, they have already been discarded.

loverofzion,

This talking point has been rebutted on this and the previous thread several times already. One, I accept the DNA evidence against Guede provisionally, not having ever seen it. If it is as poor in quality as the DNA evidence against Knox and Sollecito, then Guede’s lawyers did him no favors in failing to contest it. Two, the strongest evidence against Guede is the bloody fingerprint, followed by the bloody shoeprints. There is no evidence against Knox and Sollecito that is as correspondingly strong. Three, the forensic evidence made Guede a suspect, but the forensic evidence against Knox and Sollecito was collected after they were in custody. Therefore, investigator bias is more likely in the latter case, and I have given an example of this some time ago. Four, there is no guarantee that all evidence collected and analyzed by a given lab is necessarily of the same quality. One technician may be better than another, for example.
 
Presumably most burglars don't end up being rapist/killers either.

But I don't think anyone was ever suggesting that Guede having (alleged) prior form as a burglar was what made him more likely to be the killer. Whereas some people are suggesting that exposure to cannabis (together with totally unsubstantiated references to use of harder drugs), coupled with a so-called knife fetish, were causal and contributory factors to Knox and Sollecito becoming the ruthless, sadistic killers of Meredith that they have to have been in order to fit the prosecution's narrative.

With Guede, things are different. His having an (alleged) history of B&E and burglary mean that he has a potential means and motive for being inside the cottage unlawfully that night. And from then on, if he were interrupted by the arrival home of Meredith, it's not a huge leap to reason that things quickly escalated into something that for Guede was new and deadly territory.
 
If that were the case, why did she 'lie' herself into getting arrested? That doesn't make any sense, her sinister plot was to put herself in a cage?
I would suggest that that was not her intention. Lies that get you off the hook with your mother, or with your teacher may not work so good with the police.
 
DNA profile culled from the knife

LondonJohn,

I am well aware of the properties of blood cells you quote. We presumably can't say with any certainty that the material isn't a mixture of blood and flesh?

shuttlt,

I know of no substance that will differentially clean blood cells and leave flesh cells behind. In addition, if this knife were the murder weapon, it is difficult to imagine that some blood would not also be on the handle, and this blood would have to be cleaned. Yet, Ms. Knox's DNA was found on the handle. How did it remain?

I do not recall that you have ever replied to the pro-innocence arguments concerning contamination outside of the lab and concerning the inappropriateness of Stefanoni's DIY low template number DNA analysis.

So, Guede is no more intrinsically given to rape/murder than anyone else, based on his history? I had thought I was countering the claim that Amanda and Raffaele were intrinsically not given to murder because they were "honours students".

With Guede, things are different. His having an (alleged) history of B&E and burglary mean that he has a potential means and motive for being inside the cottage unlawfully that night. And from then on, if he were interrupted by the arrival home of Meredith, it's not a huge leap to reason that things quickly escalated into something that for Guede was new and deadly territory.
But, if Amanda and Raffaele had been in an escalating situation? Might they not have done things that were new to them also?
 
Interesting that the doubts about the "theories and forensics" apply only sofar as amanda and raf are concerned.
Never are any doubts expressed about the forensics when they pertain to Rudy Guede.

Guede's handprint was found in Meredith's blood in Meredith's room. It was found before the police even suspected Guede, let alone had any discussions with him. This evidence is 100% cast-iron solid evidence that Guede was in Meredith's room at or after the time of her death. Handprints can't appear by contamination, and the only other possibility would be a hugely complicated police framing job - in which the police either pulled Guede's prints off their records or broke into his apartment and found some latent prints there, then constructed a 3-dimensional facsimile of Guede's hand, put some of Meredith's blood on it, and made a fake Guede handprint with it.

Quite obviously, this possibility is ludicrous. Therefore the handprint in and of itself proves that Guede was there at or shortly after the murder. Guede knows this; his lawyer knows this. And this is why he's had to come up with this cockamamie story along the lines of "oh yeah, I WAS there, sure, but I had nothing to do with the murder, honest, yeah, I just stumbled upon things, and tried to help poor Meredith after the real murderers had fled the scene etc etc etc".

Oh, and his haplotype DNA evidence found inside Meredith's genital area is....erm....a bit of a problem for him also. It too was found long before his arrest. It led to him making the ridiculous and offensive claim that he and Meredith had consensual sexual relations earlier that evening - something which Meredith's English friends testified would be completely out of character and virtually impossible to believe.

I have no idea about the quality if the other forensic evidence against Guede. I suspect that some of the evidence gathered in the December "sweep" of the house could be rigorously contested if need be. But I'm afraid that the handprint evidence, coupled with the DNA inside Meredith - together with Guede's half-cocked attempted explanations for both those pieces of evidence - would almost certainly be enough to convict him of murder all by themselves.

Oh, did I also mention that he was out dancing and partying a few hours after the murder? Or that he fled town and went to Germany within 48 hours of the murder?

It's my understanding that Michael on PMF has been banned from here, so posting his words from elsewhere may well be a breach of the rules, LJ.

Well, Fulcanelli's been banned from here. But Michael from PMF continues to insist that he is not Fulcanelli from JREF. Are you accusing him of a charade?

She did find it disgusting, not appealing. She was being funny/ironic:

"im in love. i meet her roommate molly. the house has a kitchen, 2 bathrooms, and four bathrooms. not to mention a washing maschine, and internet access. not to mention, she owns two guitars and wants to play with me. not to mention the view is amazing. not to mention i have a terrace that looks over the perugian city/countryside. not to mention she wants me to teach erh yoga. not to mention they both smoke like chimneys."

It's a joke; that's why it's written the way it is.

P.S. To smoke like a chimney means to smoke constantly, one cigarette after another.

Could be. I don't know. She could be an innocent nut as well. I'm sure there are other possibilities.

Yeah, you'd think someone would have mentioned this by now, especially poor Raffaele who would know for sure!

They're called something to the effect of 'control samples.'

It is. Only it is not just random objects that are collected -- it's everything from the scene. Yes, it would have been ridiculous to take Raffaele's whole kitchen, but that's because there was no evidence Raffaele's kitchen was involved in the murder.
 
They're called something to the effect of 'control samples.'
That may very well be what they are called, but are they collected as a matter of routine? If the police pick up a knife from under a park bench, say... do they pick up some random beer cans, or any other litter they can find to act as a control?

This is an American idiom, as I recall you're from the UK and may not be familiar with it.

But it isn't really gathering control samples if you only take things that you expect to find something on, is it? If you want to use control samples to rule out contamination you would take things that you don't expect to find anything on, and in the event that you find something you can conclude contamination of some sort.
 
suspicious

It was all planted by the cops. It's already been shown that they are corrupt evidence planters. Reasonable doubt?

shuttlt,

The police withheld data from the defense. RoseMontague and others have recently pointed out that they misrepresented the amount of DNA on the knife and the fact that the TMB test came back negative for some of the luminol-positive evidence samples. They made a big show of collecting the clasp, passing it around like a joint at a Pink Floyd concert (thanks to another commenter for that image), before they knew the results of the test. DNA testing on sample 164, blood on Meredith’s wall, was discontinued after a negative preliminary quantification result. The knife tested negative for blood and gave reading of “too low” in its quantification result, yet Dr. Stefanoni continued the DNA test. Why was the knife treated differently from sample 164?

All of these issues sound suspicious to me, raising questions of bias and fairness, at the very least. Moreover, it is easy to add to the list (the Stardust file and the damaged drives, for example). However, you have not commented in depth on the majority of these matters. Why not?

It's a good thing that what a person could be or could do is not as important as the evidence against him or her. If you raise an objection every time someone says the evidence shows that Amanda is innocent, you are showing bias toward guilt.

You take everything that is in the environment of the crime. If you want to frame someone with a knife, though, you should at least take the objects that are in the environment of the knife.
 
People seem quite happy to believe in conspiracies involving the police, the prosecutor and the lab against Amanda and Raffaele. The police supposedly collected the bra clasp and the knife because they needed the evidence and knowing what would be on it afterall.

'Never ascribe to conspiracy that which can be explained by sheer incompetence.'

Stonewalling, CYA and scapegoating aren't conspiracy, they're what happens when institutions screw up bigtime but think they can still lie their way out of it with perhaps a little slight of hand.

But again, if the police had always intended to frame Guede... perhaps that was there plan, but Mignini wanted to frame Amanda and hence where we now find ourselves.

Nah, no real frame-up, in fact I think Mignini actually believes Amanda was guilty. Most of the cops probably do too, even the ones who might have played with the evidence a little, so as not to 'confuse' the jury.

Some people also believe in conspiracies about the JFK assassination, the Moon landings and 9/11. I don't. And I don't believe there was a conspiracy here either. I believe that mistakes were made as a result of confirmation bias and generalised incompetence.

I don't think there was an effort to "frame" Knox or Sollecito. I do, however, believe that the police and prosecutors felt under enormous pressure to justify their early triumphalism at having "solved the crime" on 6th November, and that this led them to assess the evidence in a biased and leading manner. Just one indication of this was the way the knife was tested - Stefanoni was told whose DNA profile to look for (which goes against all the tenets of good, independent laboratory testing procedures), and she kept going until she found it.

Here's a question: how do you think that the police came to have Guede's handprint in Meredith's blood, in Meredith's room, by around 15th November 2007?

I comment on what interests me, and what strikes me as most wrong interests me most, on the whole. I think your posts, particularly where they are purely factual, are amongst the best on the forum, hence I don't comment often. Probably for that reason I haven't built up enough knowledge on this stuff to give you a run for your money.

In so far as the information available on the internet goes, I think your case about the DNA is pretty well argued. I'm genuinely curious to see how it plays in court. Perhaps there is stuff we don't know, or stuff that we are misinformed about that will make a difference.

Having said that, if you mean to argue that the police, Mignini, the lab did these things deliberately, then I don't see how we can rule out them having done the same, or worse to Guede.

No - people in the UK "smoke like chimneys" too! Although thankfully not nearly as much as they used to :)
 
Knox and Sollecito are "dangerous monsters" now, according to Harry Rag! I do hope he gains a sense of peace and perspective in the New Year. He certainly needs to.
