You've put your finger on precisely the main points the police are suspicious about. Although he keeps insisting he did everything alone, the police ask why the sister and mother in the house didn't hear anything, especially since they were expecting Sara to show up and had an ear open, so to speak.
Also, during the initial confession, the uncle said "I put her body in the car and then WE parked the car, that is, I parked the car". They say this lapsus betrays what his confession. I'm not sure if he says he used his tractor or the car, but yes it wouldn't be easy, although physically he is quite strong from the agricultural work he has always done.
Contrary to previous news which confirmed that Sara had in fact been raped, they now say that after 40 or so days in water the DNA results don't give this information. They are trying again. So this is still up in the air.
She was at the bottom of a well in the field of the olive grove, covered by rocks and debris. Had he not confessed it would have been just about impossible to find the body there.
When Sara didn't show up, at 2:48pm the cousin called her on her cell phone, didn't have an answer, then tried again and the phone didn't ring anymore on further tries. If in fact the cell phone was in the garage with Sara, why didn't they hear it ring from the house?
Also if, as the uncle claims, he had twice before tried to molest Sara, why on earth would she go into the garage where he was alone to greet him, instead of going into the house or just ringing the bell at the gate for her cousin?
The defense lawyer looks like he is trying for mentally unfit status for the uncle. If that happens, he can be found guilty but mentally disturbed and therefore would go to an institute rather than a jail. He is currently in prison, in isolation.
Yes, in Italy there are trials but not by jury. The judge or judges decide based on the evidence.
The justice system here doesn't work well at all. There are lawyers and judges who work well of course, but many are politically oriented and go after their adversaries on that basis. Also, their orientation is for clemency, and here even if you kill someone, they bend over backwards to not convict. A recent example. On the main highway this summer a Rumanian (who are now free to circulate in Europe since they became part of the European Community), was driving a truck and bumped the car in front of him, but didn't stop. The car (driven by an Italian) followed him and when the truck stopped at the exit to pay the toll, he went to the driver's window telling him to pull over and stop, the driver was arrogant and told him off.
So, the Italian laid down on the road in front of the truck to stop him from leaving until the police showed up.
The driver ran right over him, obviously killing him. The police stopped and arrested the driver. Brought to trial before the judge, it was determined that he hadn't realized that by driving over the man he could have killed him, so he was let out.
You really have to bend your antennas to come up with something like that, and the people here are sick of it, it is an everyday story. Because he was a Rumanian it was a politically sensitive situation and the judges are on their side. Another time, a drunken Rumanian ran his stolen car into a bus stop filled with commuters, he also got off with a warning. And of course, knowing this, any delinquents etc take advantage and get away with murder, also literally. That's how the system works here at the moment, and there is hugh and heavy resistance to change it, although the government is trying to make changes. Which is why they are under attack.
Back to Sara, since the uncle is Italian and there is a lot of serious public sentiment about the case, he will not be dismissed but could land up in an institute.
