He never confessed to killing her but admitted being in the cottage and in the murder room and told his best friend she wasn't involved and some mystery Italian dude knocked on the door while he sat on the toilet and did it. As time went on his story started changing to include them. He said he saw her silhouette while he leaned out the window which happened to be the broken one in Filomena's room. At one point his lawyers were saying a guy seen at the fountain the morning after the murder might be the killer. The only time he ever faced questioning from the defence lawyers was at the last appeal and he handed a letter he couldn't read to Mignini who read it for him saying they killed her. The prosecution and Kercher family lawyer objected to the defence questioning him about the murder.
Yes, that's actually what I meant by his confession; sorry my question was poorly worded. Thank you for the explanation. The tenuous (at BEST) relationship between the three of them has been one of the sticking points with me in favor of their innocence. It just seems so impossible to me that the three of them joined forces and RS and AK held MK down so RG could murder and rape her that night. All without leaving any DNA behind. I know, I know, the metal bra clasp. I think Bill said it best in regards to that. Is there any proof that they ever spent any time together or knew one another? I thought he only knew of them because he spent a bit of time with the neighbors.
Also, the fact that some think AK and RS were drug-addled the night of the murder, but not so much that they could clean up their own DNA from the murder scene, while strategically leaving all of RG's DNA behind. But then as careful as they were to clean up all of their DNA from the murder room, left RS's footprint on the bathmat. (I don't think it is RS's footprint on the bathmat, BTW)
Hope this makes sense, sometimes the coherent and persuasive thoughts in my head don't come out as smoothly in the written word.
