I think they became suspects because the police couldn't find any leads, and then started looking for anything they could find, like this. If you want to find suspicion anywhere, you can find it. It's almost impossible for two people to give the exact same story, memories differ, people concentrate on different things.
Look at it this way, you're asking questions right now and getting different answers from the people currently posting. Some know more, I know less, and they all vary. You'd have to hardwire people together to get the same exact accounts.
I like Raffaele, he's got a great sense of humor, read his diary sometime! He also
went to the police station stoned on hash! I find that hilarious, but I have a wretched sense of humor sometimes. It also is a pretty good indication he didn't think he had anything to hide, he even forgot to take his knife off before entering the police station. I love his line in the diary about that.
However I cannot read Italian, the vast majority of people posting here can't, so it's tough to find out much about him, and frankly he's kind of peripheral to the one they wanted: Amanda. He wasn't part of their theory, which originally included only Amanda and Patrick, he just got roped in because he reverted to giving Amanda an alibi after they 'psychologically tortured' him as he puts it in his diary.
I was reading from an Italian poster at the forum of the site I linked that in Italy Raffaele is the one they care about, Amanda is kinda forgotten. I suppose that figures if you think on it.
Personally I think Raffaele smoked a little too much hash. Amanda got mindspanked by an aggressive interrogation in which they tried to convince her of things that were not true in place of what she thought she remembered in my opinion. So what is she supposed to think, what the police told her she did or her hash-addled memories that she was told didn't happen?
Perhaps we should consider this a case study in the short term memory effects of hashish and angry policemen.
As far as I know nothing is known of Raffaele's interrogation outside the entry in his diary where he states he was 'psychologically tortured.' There is of course no tape available, which is kind of curious being as they set them up with a 12 man crew and wanted to place Amanda at a crime scene and sign a 'confession' without a lawyer. They apparently taped all but a couple of the other girl's witness statements, but not their crown jewel, Raffaele and Amanda--the ones they charged with murder.
I think they're lying.
Because he remembered something Amanda didn't. It looks all sinister in the paper doesn't it? The papers and/or prosecutor made them look ultra guilty from the start, the police even said they had Amanda on camera going into her home right before 9 PM, it turned out that was Meredith. The press convicted them quickly and none of it turned out to be true, but most still thought it was I bet. Wait until you get to the one where the police released a picture of the bathroom treated with a chemical to make everything look blood red: to imply the bathroom was totally bloodsoaked when Amanda took her shower. It wasn't true.
