it looks to me at least circumstantially she could be involved and is at the least a wild woman.
the Italian guy looks even worse
the African guy maybe even more so..
the other black guy...who knows?
is the prosecutor a questionable fellow?...indeed
but my hunch is she is not innocent, though she may not be guilty directly or she may have helped facilitate or cover up...
1. The black drug-dealer from the Ivory Coast, no question, DNA evidence in the room, etc. He was convicted and even he hasn't continued screaming, "I'm innocent."
2.The club owner, born with a guilty face, so it's hard to tell.
3. The Italian boyfriend of one week, don't think that he did it or had any part in it except to cover up.
4. Amanda, don't think that she did it, but I think that she knows more than she is saying.
Here's a hypothetical scenario:
Amanda and her boyfriend get really high on drugs in the apartment -- maybe even the Ivoirian drug dealer is there, because they know him & invited him in. After getting high, Amanda and her boyfriend retire to have wild sex or fall asleep. Maybe they hear something going on in the other girl's room, but they either write it off to rough voluntary sex or rape, but they are so high that they don't care. Never crosses their mind that the Ivoirian guy is actually killing her roommate.
Amanda wakes up in the morning and still hungover from the night before goes in to take a shower. She sees blood but doesn't trust what she's seeing or what it might mean until the shower fully wakes her up & brings her back to reality. She gets out of the shower, checks the other girl's room and finds her dead. She wakes up the boyfriend and tells him. They both panic. Because they let the drug dealer in and got high with him, they figure that they are going to get implicated. So in a state of panic, they try to cover up what happened. They break the back window of the girls room, lock the bedroom door, and leave the apartment to go think out what to do next and to get their mutual stories straight. They then come back to the apartment, pretending like they just arrived and the police show up. They tell the police their stupid, unverifiable story and the whole sorry police/court show takes off from there.
This hypothetical would explain, the footprint in blood, the rest of the circumstantial evidence, and the bizarre behavior by Amanda and the boyfriend afterward.
This is just a hypothetical, but once you lie to the police about something like this -- especially in Italy-- no one including the jury is ever going to believe the truth if you tell it later so you don't bother telling it.
But I do think that something resembling this hypothetical is what really happened.
