After reading the wiki article on this case, it would appear the prosecutions case was ridiculously weak sauce, i am amazed she got convicted the first time.
The guy thats in jail was probably the only killer. His bloody hand prints and finger prints were all over place, yet not so much as a partial fingerprint of anyone else in the room.
What convicted them the first time was the alleged DNA of knox's boyfriend on Kerchers bra clasp, and alleged Kerchers DNA was on a knife in Knoxs Bf's house with Knoxs handprints on the handle.
but apparently the DNA tests in more than just these items were botched and the results were really inconclusive.
I just find it dubious, aside from those 2 articles of DNA evidence, its like they were never in that room. I find it dubious, because if you rape and kill a girl like that, find it highly unlikely that is all you would leave behind, and if you were good enough to clean it up that well, I would think you arent stupid enough to keep the murder weapon where the cops can get it(and the knife in the appeal was concluded to be too big to have made the wounds in kercher). especially when the alleged third accomplice, guede, basically left enough evidence behind that it looked like he danced in her blood following the incident.
I really honestly dont think those 2 had anything to do with it.
I know they wanted it to be some crazed tabloid drama melrose place style murder, but I think the reality is, some lowlife followed her home, raped and murdered her.
