Machiavelli,
”halides1” said:
It is a better description of the situation to say that one wound is incompatible with the larger knife, and the second wound is disputed
.
No, moment.
Chris said two wounds were incompatible. Chris was wrong. Only one wound is incompatible.
And it is not a good description to say the other wound instead is “disputed”. The other wound is not disputed, whereas the meaning of disputed would be there is at least one expert who says “it is incompatible”.
But there no expert is saying such thing.
Walter Patumi and Carlo Torre indeed bring arguments against the kitchen knife, but while those arguments are logical, they never state the knife is
incompatible with the wound. And also they never dismiss the Lalli’s general principle by which virtually
any knife could have produced the wounds on the left side.
Walter Patumi and Carlo Torre - in the cited chapters - bring arguments that are logical inferences, of dynamic and psycho-dynamic nature, against the possibility that the 17,5 cm bladed knife produced the wound.
Before considering all those arguments, concerning the dynamic and psycho-dynamic logical levels, the assessments expressed on sheer size of the wounds dos not differ from Lalli's and does not define them as “incompatible” with the kitchen knife.
They do not belive the kitchen knife was used. The larger wound is anyway physically compatible with the kitchen knife.
You state that the court rejected Torre's and Patumi's expert opinion; therefore, the matter is closed.
I didn’t put “therefore” in that sentence. Personally I think the matter is closed because I found Torre and Patumi’s arguments not convincing, and because I found the court’s opposing arguments convincing.
The first non convincing defensive argument is that the blows were all intended to kill and “very violent” , and that a killer would have used his whole strength and plunged the whole length of the blade.
This argument is in plain contradiction with the evidence, and with the other defensive claims. The physical data of these wounds show exactly the opposite: it is proven that the killer
did not use his/her whole strength and
did not use the whole blade lenght. This is obvious since the alleged weapon is claimed to be 8,5 long, while there is one wound only 4 cm deep, and another on the other side only 1,5 cm deep. It is obvious that the killer did not intend to assoult with full might and full violence on all these blows, and that the blade did not penetrate entirely in the victim’s body. So the logic assumption of this psycho-dynamic argument – that the blade would be plunging to its full depth - is contradicted by facts. A knife was used multiple times with its blade plunging only partially and not with full force. Moreover (a secondary observation) the blows show an uncertain intent to kill also in their orientation, they are not using the cutting edge of the blade and are not directioned to slash the throught, they are also disomogeneous and on two different sides.
The second unconvincing point is due to another grave contradiction of the defense theory. It is Introna’s and Torre explanation of how the large wound was produced by plunging a 8,5 long blade three times going back and forth. Which means, a 8,5 cm long blade should have been used with a motion back and forth three times and with full force. This dynamic is contradicted by the analysis of the internal section of the wound, the tri-dimensional path of the wound through tissues: there is only one point of arrival of the blade, whereas there are no “second” and “third” paths for a second or third penetration of the blade from a different angle. This back and forth movement of the blade to produce the cut is therefore impossible.
However, I still see no reason to discard the hypothesis that one knife was used to make all three of the wounds, whereas the hypothesis that the kitchen knife was used demands a second knife even in your scenario.
However, I see one reason more. On the bed sheet there is a print left by a knife showing a blade about 12-13 cm long. This print shows a blade not entirely compatible with the right wound (1,8 mm at 4 centmetres) and anyway too long to fit with Torre and Patumi’s theories of an 8,5 cm blade.
