The problem with this is there is zero credible evidence Amanda and Raffaele were at the cottage that night, so that leaves Guede there by himself or Guede with one or more accomplices.
I've eliminated Amanda and Raffaele as suspects because of the lack of evidence suggesting they were not at Raffaele's apartment as they stated, something I could never do with John and Patsy Ramsey, because they were in the house when JonBenet was murdered. Clearly I think they are innocent, though.
John Ramsey did it.
