The police chief's boasting is irrelevant. Even Miginini called it "stupidity" in the Graham interview.
Actually that's how they
really do it, they corroborate information from suspects and do their investigation before they do their arrests. That's what they produced before Mattenini on the Eighth, the 'evidence' they thought would help prove Amanda, Raffaele and Patrick were involved in a bizarre murder. The 'buckling' comment strongly suggests they were suspicious of Patrick before the arrest, being overly concerned with Amanda's mistaken text in
all versions of the interrogation, including their own, but also Amanda's and also what we know of Patrick's also indicates the police thought that an important 'admission.'
So when Amanda tried to tell them later in the day she wasn't sure of all this, that it seemed like a dream, a result of all the hitting, yelling and threats, and them telling her they had 'hard evidence' she was at the scene and her being deprived of sleep, what did they do? Called her a 'compulsive liar' and said she 'changed her story three times' which is a bizarre way to interpret those three statements.
It also suggests they must have had other reasons to be suspicious of Patrick, another thing proven by the 'evidence' against Patrick produced before Matteini. Otherwise, if all they had was what they had from Amanda, how could they 'know' she was lying about the night of the murder? What gave them such confidence they refused to reconsider their arrest of Patrick? Do you suppose they thought cherry picking lines completely out of context actually solves this conundrum?
By no means was it coincidence.
She fabricated it beacuse she did not know what Raffaele had told them and they were asking her about Lumumba's SMS.
Why weren't the cops talking to Raffaele about the murder? Isn't that extraordinarily odd? They're going to arrest him anyway for the murder, but once they get that signed statement from him about he and Amanda splitting up at the town square and that strange 'admission' that he called the
Carabinieri after the Postal Police arrived, he just
sits there while the police go after Amanda about
someone else. How do you explain why the cops didn't automatically think the new boyfriend of the girl they're suspicious of was her accomplice, and instead spend hours putting the screws to her about
someone else while he'd broken down and given them everything they wanted already?
As I read it I have the feeling that it is a damage control.
She would like to retract it without definitely retracting it because in that case she could not answer a lot of questions.
The first one: Why did she accuse Lumumba?
Better question is, why did the
cops think she'd accused Patrick? Why did they think that gibberish was credible, and didn't probe her for more details, as in
anything outside the fact that Patrick was there, and she 'vaguely' remembered him killing her, or she 'confusedly didn't actually remember him killing her' and nothing about the break in, how the murder occurred, (he had a weapon on him?) or could have, (did he normally carry a knife?) whether he actually did it, as in, she's standing in this timeless void about to be teleported back to Raffaele's bed, yet the murderer never emerged from the bedroom?
If the cops version of the story is true, and she was acting strangely and all of a sudden blurted out that Patrick did it, (ever wonder why
that line didn't make it into either statement?) why did they accept these two 'vague and confused' statements as fact, rush out and arrest Patrick ostentatiously without bothering to investigate at all, then refuse to accord her note any significance except of her 'lying'--yet claim that her account corroborated the facts of the crime as they knew them?
It is no wonder that she broke down before Mignini on Dec 17.
She fully knew that in the 5:45AM questioning and confession there were no beating, yelling, etc. And she did not have the courage to tell into the Mignini's face that he had coerced her. Because he did not and Amanda knew that. So she again availed herself of the option of not responding.
Or maybe talking to Mignini sometimes isn't a pleasant experience?
