Sorry you believe the idiot prosecutor. His version of events was a psychotic fantasy that was completely fabricated.
Then entire Italian system of ‘justice’ is as convoluted as it can possibly be.
There was the matter of her DNA on the knife that ended her roommate’s life and Amanda’s association with the scum that surrounded the victim as she died of multiple knife wounds.
What was Amanda doing at the scene? Paring her toe nails?
This was a sick, needless crimes (most are, of course) but this involved sex, drugs and animosity toward the roommate.
Now that's a problem.
