Very interesting: the conversation in the afternoon of the 5th of November (hours before the interrogation) with Dolly - they talk about suspects:
Dolly: So they don’t have any suspect?
Amanda: Well, yes, they have, but they don’t tell me…
Dolly: But it wouldn’t be the guy you were afraid of, would it?
Amanda: Ehm… the guy that…the only guy I know who is certainly a suspect is one I only met once because… ehm…I decided never to talk to him again because he took me to his home in the middle of the night after telling me he would be taking me to my place, that is to give me a lift home, instead he
didn’t take me home and did so only after about one and a half hour later, after arguing with him, telling him I wanted to go home, “Take me home!”, and he: “Alright”. I didn’t like that and told him so. He was a guy who met up with Meredith and her friends often, when they went out, so he is a suspect, I know. I mean: they don’t tell me who is suspected…
Amanda is talking about Shaky (Hicham Khiri), a black man. Do you have any explanation why she 'fingers Patrik to cover up for Rudy' hours later without any suggestion of the police and although the only suspect she guesses is Shaky?
A 'friendly atmosphere'? Read what Amanda says about the 3rd and 4th Nov police interrogations in tapped phone calls. Keep in mind that these interrogations were before Raff dropped her alibi.
Tapped phone call with Annie Fuller on 5. Nov 18:20 (talking about Nov 4th):
Amanda: Yes, in fact my battery got flat and in any case I spent the whole day at the Police Station.
Annie: Good heavens! How did they treat you?
Amanda: It’s a little frustrating because… that is, they are very stressed and become more impatient with me and then… yesterday it’s been very difficult because when I went to the Police Station they questioned me and when I tried to reply they were telling me: “Are you’re lying? Are you sure you’re not lying? Because if you’re lying you are getting yourself in big trouble”, and I: “I’m not lying, I’m trying to help you”, you know?
Tapped phone call with Doroty on 5. Nov 19:00:
Doroty: You seem much better than yesterday.
Amanda: I am much better than yesterday, yesterday I was going crazy and even though I’m not in perfect form, today I function better, because since tis happened (- - -) they bombarded my mind and today I was able to not think about it, which is very positive
And last but not least, the thing that she had insider knowledge (rape). Read the tapped conversation with Dolly in the afternoon of 5th Nov:
Dolly: Has she been raped?
Amanda: Well, that was the point: They asked me about her sexual life because it seems as if she had sex with someone but they don’t know if it was consensual or if it was a rape situation. They asked me questions about her sexual life, such as: was she having sex with someone… whom she had just met?, if she was doing some things during sex, so I don’t even know what the hell this guy did to her but it seems strange.
...
Amanda: … they only ask me questions, but from the questions they ask me I am in a position to understand who the suspect is, because they go: “ Do you know anyone tall who comes to your house?” And I: “Ok, great, then it has something to do with a tall person”; “Tell me something of Meredith’s sexual life”, and I: “Oh, great, she’s been raped.” Eh, eh, eh!
Amandas statement to police 6. Nov 1:45 AM:
I struggle to remember those moments, but Patrik had sex with Meredith, with whom he was infatuated, but I do not recall whether Meredith had been threatened beforehand.
