Just dowloaded the second version of the translation of the CNN Mignini transcript, which is somewhat clearer in this section:
Mignini: The magistrate, the prosecutor has an obligation, let’s say, in the current legal system, to seek, he is an impartial body, that has the obligation to seek the truth and if new evidence emerges which make [a person] appear to be credible, which make a person appear to be unrelated to a crime, [then the prosecutor] has the obligation to request that all charges be dropped or, if during the trial, [to ask for an] acquittal. I myself have come across many times, during a trial, in light of witnesses, new witnesses, who were produced again in other cases, I asked for an acquittal. Anyone who knows me knows that this has occurred many times.
But in this case I had, let’s say, during the investigation phase and during the trial, I made, we made our requests, we explained them, we justified them, and the court gave, acknowledged the validity of this case. Then there is an instance of appeal. There is the appellate level. Now, I will not discuss this because it is on-going.
49'11'' Mignini: The phone call, for example, another thing that had a considerable influence on the investigation was the phone call that Amanda had with her mother in the middle of the night in Seattle, even before [the body] was discovered. This is another thing that comes to mind, even before the body was found.
19'52’’ There is a call that is made in an hour, now I do not remember, it was I think, I do not remember exactly, I think it was 3 AM in Seattle, I think.
