JonBenet mystery

I can't seem to get my head around this, I was confused at the time this happened and now more confused that this guy had confessed to the crime. What I don't get is that when she was kidnapped, was she always in the basement? and what about the time line from when she was taken to when they found the ransom note, and to when they found JonBenet in the basement. None of it makes sense. on this web site www.thesmokinggun.com you can read info about a lot of things. what I read was the ransom note and it would seem to indicate that there were 3 people involved in the kidnapping. well if she was kidnapped and kept in her own house, how did they get in and how did they get out. What I am trying to find out is what the coroner found the official time of death to be. Also you can find info of when the police searched John Karrs' house in 2001, after a friend of his told police that he confessed to her as being the one to murder JonBenet. the police found in his house details and a death certificate of a 16 year old girl that was murdered. Another man is convicted of this crime and why was Karr so interested in it. What do you think, is this a really bizzare case.
