Just dowloaded the second version of the translation of the CNN Mignini transcript, which is somewhat clearer in this section:
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.
It's funny how a phone call like that can be construed to be ambiguous and suspicious by saying it was made before the body was discovered and that it was 3 in the morning for her mother. The phone call was made at 12:47, just three minutes before Rafaelle would call his sister asking her for advice and she then told him to call the police. So basically Amanda had returned to the cottage with Rafaelle, seen the broken window and blood, called their relatives and then immediately called the police. But of course, we can make this suspicious by simply reducing it to "nothing had happened yet" as if there was no reason to call her mom, but as usual we then have to ignore the context of the other calls immediately afterward.
