\link{http://groundreport.com/meredith-kercher-crime-scene-instigation/\this is fascinating} - a detailed account of what happened when on the day Meredith's body was discovered. It explains a lot about the mixed DNA, bloodstains, translation confusion, timings.
The writer is 'a member of Amanda Knox’s Greater Seattle Area community' - according to one of her comments below the piece, she has access to information not publicly available.
Also:
'Just after Luca breaks down the door, Paola screams, “Blood!” and Filomena begins screaming “A foot! A foot!”
'Filomena is screaming and hysterical, Amanda thinks that they have just found a severed foot and tells her terrified mother that she needs to get off the phone to give the police her full attention.
'She hears someone say “armoire” and thinks a foot was found in the armoire in Meredith’s room, then she thinks that Meredith has been stuffed into her armoire. Raffaele finally helps her understand that Meredith is lying on her floor, in front of her armoire, with her foot was sticking out from under her bedspread.
'Luca, Filomena, Paola, Marco and the police are the only ones to see inside the bedroom, but no one yet realizes that Meredith has been stabbed in the throat.
'Luca sees Battistelli lift the blood-soaked bedspread covering Meredith’s body so that he can confirm she is dead. Battistelli has now contaminated the murder scene but would later deny entering the room until Luca confirmed it.'

Italian policeman lies. Who'd have thought it 
(& there is the body in the cupboard idea)
also:
'All six young adults were sent to the police station to answer more questions, Amanda and Raffaele would ride with Marco and Luca. It’s then that she finds out from Luca that Meredith’s throat was cut ; Amanda breaks down and cries all the way to the police station, Raffaele comforts her as best he can.'
'After the arrival of the medical emergency team, a paramedic tells Luca that Meredith’s throat was “slashed” and she “suffocated” on her own blood.
'Luca provides this detail to everyone in the car when they are on their way to the Questra more than two hours after the discovery of Meredith’s body.
'Amanda later repeats the detail to Meredith’s British girlfriends, about four hours after Meredith is discovered, a few days later the police spin the story that “Amanda only knew details a killer would know” fueling the smear campaign.
'In reality, the court record demonstrates that all of the young adults present were clearly sharing information amongst themselves and at that point in time, due to the language barrier, Amanda knew far less than the five young Italians.'
