This just seems to be a really simple case complicated beyond all reason. And the result of these complications is that two completely innocent bystanders have lost four years of their young lives and been irrevocably altered by the experience.
Rudy Guede, a habitual cat-burglar, decided to rob the flat where Meredith lived. He knew there were a couple of foreign students there, and may have anticipated good pickings. While he was in the flat, Meredith returned home. Some sort of confrontation ensued, which escalated to sexual assault and murder. Not necessarily in that order. Rudy fled with some small, easily-portable items and cash, but when one of the mobile phones started to ring he realised this might not have been such a good idea. He accidentally initiated calls to stored numbers (the first on the list being "Abbey") while trying to turn the phone off. Panicking, he ditched them. High as a kite, he went dancing after he'd cleaned up, possibly thinking he might establish an alibi. He later fled the country.
Amanda spent the night with Raffaele, in his flat, doing whatever new lovers with some cannabis do in that situation. Amanda got a message saying she didn't have to go to work, and she turned her phone off to prevent any message reversing that decision from getting through. The next morning she returned home to shower and collect some things she wanted for the planned trip, and began to realise all was not well. In a foreign country, and not speaking the language very well, she returned to seek Raffaele's advice. He was unsure what to do for the best, and hesitated to apply serious force to Meredith's door. He called his sister, who told him to call 112.
And the rest is just a bunch of incompetent and arrogant cops jumping to wildly premature conclusions, then digging themselves even deeper as evidence emerged to contradict these conclusions, in a CYA scenario of escalating dishonesty and lies.
The Norfolk Four case is an extremely close parallel. Why do some people find this so hard to understand?
Rolfe.

Well said.
