yeah, that case can be a black hole if you let it
Yes, I haven't followed this case closely in quite a while but where was following it was at the 2+2 site mentioned earlier and there has been exhaustive back and forth to the point where its exhausting to keep up with and understand. One of the posters argued that one of those 5 prints (IIRC it was 5), the partial print was consistent with Amanda's show size.
Yeah, but it doesn't look anything like shoes she had and did look like a partial print of Rudy's. It was the
size that was similar, nothing else was.
I think I follow you but it still gives me pause that Rafs DNA was on a bra strap it had no business being on. If you're saying that one in every four males have the same Y-haplotypes, then I don't think it would be accurate to say its Raf's DNA.
Not quite, autosomal STR is what most think of when DNA analysis is mentioned in court cases, it's the test that can (sometimes) determine who the contributor is with a confidence that it was them or their identical twin. This test for the bra clasp test was based on partial data and as such could have matched one in four people in the courtroom as Conti or Vechiotti said at the appeal. Worthless, too many contributors, too small a sample, too much (almost certainly) masked.
It wasn't accepted at the Massei court either, he relied in the Y-haplotype which is not something that can identify to that degree, more like a blood test. Just how rare Raffaele's Y-haplotype is was unknown in 2011 (there's a database we checked but its incomplete) but there's enough of them that odds are that Y-haplotype suggests it was Raffaele's DNA. That doesn't mean that DNA
means anything though, this is
not the sort of DNA testing that is used in American and British courts.
Seems that would be like saying because they found blood that was type O and Raf is type O, then its definitely Rafs blood. At best all they could claim is that it was Raf's blood type.
Yes, kind of,though there are many more Y-haplotypes than blood types. However keep in mind even if it was one of a thousand that in Perugia there's a hundred thousand people, thus a hundred people could have also have contributed that Y-haplotype. When you consider all the people we
know were in that cottage just after the murder, all the Police, technicians, the boys who were at the discovery, the prosecution, the photographers etc each and every one of them increases the chance that one might have the same Y-haplotype. It's kind of like the fact that of a class of thirty people, odds are someone will share your birthday, it's not like it becomes 30 of 365 when calculating the probability.
My
guess is the odds would indicate that Y-haplotype suggests it was Raffaele's DNA, but that's off incomplete information. It's certainly neither definite or anywhere close to that, just a balance of probabilities shooting in the dark.
While this may be a technical grounds for dismissing the case, in my limited understanding, it would still make me scratch my head as to why its Raf's DNA. Time and contamination doesn't automatically end up leaving Raf's DNA. I'm not trying to dismiss what you said here, I'm merely letting you know that his DNA, if in fact thats what it was, on the bra strap shouldn't be there regardless an I'm left wondering how it got there or forced to try and make the argument that the police deliberately planted it which I have no evidence to claim.
The obvious one is contamination, it laid in a pile of dust and trash for weeks on end with stuff blowing around, that's (very probably) why there's a total of four males in the clasp. For that trace amount of Raffaele's Y-haplotype to
mean anything it has to suggest he was actually the one who put it there, meaning he touched the bra clasp. That's why C&V found it unreliable, there's no reason to think Raffaele (and three other men) touched that tiny bra clasp, but under the edge of a dirty rug is an excellent place to find the sorts of things that might transmit trace and partial DNA.
Also Stefanoni's lab wasn't equipped to handle LCN/LT DNA, trace DNA transfers (and thus contaminates)
much easier It's the difference between something that might adhere from me to you when the wind is blowing and me having to hock a lugie in your face to get a decent transfer. HUGE difference. Contamination with LT/LCN is not a rare occurrence, it's something that special (beyond sterile) conditions must be employed to try to prevent. C&V go into that
here.
No need to go find the cite, but I'm all for cites whenever possible
Massei PMF p. 214 said:
she was asked to specify which elements needed to be present in order to preclude the possibility of identification of a collected biological specimen, Dr Stefanoni indicated an incorrect storage of the specimen in an environment which was not ideal, such as in warmth, or enclosed in a plastic bag where water might be present and, not being able to evaporate, it facilitates the proliferation of micro-organisms. She stressed that the consequence of a conservation carried out in an incorrect way was the deterioration of the specimen so that, when analysing it, very probably ‚no genetic result would be able to be obtained‛. She added that the circumstance for which it had been possible to attribute the specimens gathered meant that the conservation had been correct.
Lo and behold when the independent experts went to re-test the bra clasp and reproduce her results they found:
C&V said:
The item to be examined was observed by us to be locked inside a transparent tube with a red top, contained in turn in small sealed bag [bustina sigillata], of transparent plastic, of the State Police.
We emphasize, moreover, that — as shown photographically — multiple components of dark-red color were present, scattered throughout the inside of the tube, both at the bottom and near the closing top.
There were two clasps, both lacking grommets [senza l'occhiello di tenuta della controparte], with extended parts of red-brownish color, others of reddish color; whiteish elements were also partially in evidence.
One of the clasps was recognizable in its original form, with the characteristic square upon which the corresponding round-edged hook is sewn; the other no longer had any kind of shape, as it was so completely deformed as to have been inserted into the first [clasp], with which it was partially fused due to the presence of rust; separation of the two elements would involve the fragmentation of certain rusted components.
One rule of scientific work is reproducibility. When
real scientists do tests like this there's samples left that can be retested years--or decades--later, you've probably heard of re-tests exonerating people. Neither of these pieces of evidence, hailed as the best evidence against them, could ever be re-tested,and one decayed in storage under the auspices of the one who presented such dubious work in court, and there's definite reason (like she
testified to it in court!) to think she knew better.
I still find that to be a weird thing to write if its true that she never went to his apartment. Its one of the things in this case that brings suspicion on himself.
Note that he's trying to figure out if
Amanda had taken it, he's not trying to say it's any excuse for
himself, nor does he have any reason to think anyone else will see it outside possibly his sister and father if he so chooses. At this juncture he's been writing about how he's hearing reports of Amanda hanging out with Argentianians at the laundry, and of course he can't be
sure she didn't get up and murder anyone while he was sleeping. He hears about the knife in the previous entry and wonders if Amanda actually did kill Meredith, or give his knife to someone who did, and his lawyer tells him it's nothing to worry about and perhaps Amanda took the knife to the cottage as she needed it for cooking. This is a cheap common kitchen knife, 5.95 at the Italian Wal-mart, it didn't even belong to Raffaele, it came with the furnished apartment, he may never have used it, might not even been sure what it looked like. Here's the previous diary entry which I was going to post but decided not as I feared one more cite might be fatal:

Raffaele's Diary 11/16/07 said:
Nov 16 2007
Last night I saw on television that the knife that I had at home (the
one from the kitchen) has traces of Meredith and Amanda (latent) ...
my heart jumped in my throat and I was in total panic because I thought that Amanda had killed Meredith or had helped someone in the
enterprise. But today I saw Tiziano who calmed me down: he told me
that the knife could not have been the murder weapon, according to the
legal doctor, and has nothing to do with anything as Amanda could take
it and and carry it from my house to her house because the girls
didn't have knife so, they are making a smokescreen for nothing ... I
live in a reality show nightmare, the 'nightmare reality show'.
Unbelievable!
I am starting to have perpetual panic attacks and palpitations due to
...in the anticipation of these scientific tests that fire shots
unsettling of this sort... Oh God, it is not their fault but of the...
who take everything that they can involve in this story.
I want to think about other things, think of my friends who are close
to me and think of fathers in these moments that will stay very badly
and will be worried and I am very sorry. I do not know what to do.
Please Jesus give me the strength and reason to deal with this
situation and I pray to support also dad who is sustaining an absurd
situation.
So he takes Tizano's assumption that Amanda could have borrowed the knife for innocent purposes and recalls a moment when he was cooking at the cottage and brushed Meredith and figures that must be the answer to why there's that DNA on the knife. He must have brushed her with that knife and if Amanda told him she borrowed it he forgot, perhaps because he was 'smoked' and it didn't register. If you go back to the last entry you'll see that's when he finally comes to the conclusion Amanda couldn't have been involved, and what he thinks is a perfectly reasonable answer to how that DNA got on the knife is what finally causes him to write:
Raffaele's Diary 11/18/07 said:
I am convinced that she could not have killed Meredith and then return. The fact that there is Meredith's DNA on the kitchen is because once while cooking together, I shifted myself in the house handling the knife, I had the point on her hand, and immediately after I apologized but she had nothing done to her. So the only real explanation of the kitchen knife is this.
It's about
Amanda and to satisfy his own worries in his own diary that there's no reason for him to think anyone else can see. If he thought the cops would seize it he probably wouldn't have talked about them so badly, nor included that bit about how he was scoping out the (police) babes in prison despite the fact he's fully self aware how that might look being in jail accused of rape-murder!
He didn't
lie to anyone, he thought he came up with a reasonable explanation that satisfied him how that DNA got there and that Amanda hadn't snuck out of the house when he was sleeping to kill Meredith, just after his lawyer had told him that Amanda might have borrowed the knife anyway. Probably made sense at the time, but it turned out that knife never left his apartment.
This is another one of those issues that was argued relentlessly on the other forum and just left me confused as to what the actual truth was. I came away thinking this issue was like watching a slow motion replay of a shot in a basketball game that went in as the buzzer was going off so it had to be rewound multiple times to try and see if the shot counted but the toe was so close to the line, each fan argued for or against based on his rooting interest. I still dont know what happened here and admit my mind is probably mush from all I read in the other thread.
The reversal of the polarity makes it confusing, I know what you mean! Go through it three times slowly, it is hard evidence and it should convince you. Look at it this way, you
know that Amanda and Raffaele were calling all over getting advice on what to do about the murder, they called Amanda's Mom, Filomena, Meredith and Vanessa, the latter of whom told them to call the
carabinieri. When the postal police arrive Amanda and Raffaele insist they come in
anyway despite the fact they are there just to return the phones.
So why on earth would Raffaele have lied about having called the
caribinieri a few minutes before or after the postal police got there? They've already raised the alarm, they greet the postal police and insist they come in, just how stupid is the idea that for some reason he decides not to take his sister's advice until
after the postal police get there, whom they greet and take inside. If they're guilty of something why would they want
more police at the scene? Why lie about any of this? This is a relic of from before there was evidence of all the people both of them had called and the idea they were trying to delay the discovery of the scene became conclusively discredited.
I didn't realize anyone (outside Mignini) was demented enough to still push that contention, it sounds like that thread is stuck in 2008!
makes sense, but I would like to have seen DNA from the other flatmates as you would expect their DNA to be there as well. Why is it only Knox's?
Why would you expect that there'd be much information of that nature about anyone else not on trial?
good point but I still don't understand why she would do this plus when I look at the picture it appears to me to show the faint impression of the heel part of whomever's foot print that was which would indicate the bathmatt wasn't moved and if it wasn't moved then she is lying about the bathmatt boogie? Why lie about this?
I never heard that one! Which picture do you mean regarding the heel impression?
