UKGuy, I believe that after JonBenet was killed by a group of pedophiles in the basement some of them rang FW for help. I believe it was he who masterminded a plan to cover up for the fact that her death was the result of a session of sexual abuse in which the killing was accidental, at least on the part of those who had been, and hoped to continue, abusing her for at least another few years yet.
I believe it was FW who told them to hide the body in the cellar in the first place, so of course he knew where the body was. When he went down there as soon as he arrived at the house the next morning it was to make sure that they had done as he told them. I believe it was his idea to stage a kidnapping; as well as hiding the body until it could be gotten rid of, they were to to hide any evidence of sexual abuse in the basement and get Patsy to write a ransom note. I believe it was his intention that police should not be called if at all possible, so he gave Patsy strict instructions to include all kinds of threats in the ransom note to frighten John into not calling the police and told Patsy that after she 'discovered' the ransom note she must call him and P and they would come over and take care of everything. Unfortunately his plan began to unravel when John told Patsy to call the police and she obeyed John instead of FW. However prior to this and long before 5.52 am, FW had also called his buddy in the BPD on his home phone to instruct him that should they receive a call about a kidnapping at 755 Fifteenth Street they were not to treat it too seriously and were not to bring in the FBI. This part of the contingency plan worked very well. After the patrol officers arrived in response to the emergency call it took another 2 hours before a detective was sent by John Eller - just one lone detective, and she was the only detective there for hours and hours, despite her calling repeatedly for backup, right up until after the body was found. When the FBI did arrive JE sent them away saying the BPD could manage the case themselves.
Finding the body in the house was not part of FW's plan. His plan was that once the police and everyone else had left the house he would offer to 'stay on' 'just in case' the kidnapper should call, giving him the opportunity to remove the body from the house and dump it in the mountains. This part of his plan failed because he had not told JE that there was a body hidden in the cellar which he did not want found, so JE had not instructed Arndt to keep everyone on the ground floor of the house and not to allow them to go beyond there to where they might find the body.
Patsy has stated that JonBenet normally slept with her hair pulled back in a single bunch. I believe this was just the hair on the top of her head pulled back from off her face and would have been perfectly comfortable to sleep in. I believe it was the pedophiles who wanted to operate the neck ligature effectively who pulled the rest of her hair up in another two bunches to get it up away from her neck.
The necklace was not entangled in the ligature.
There was a small amount of hair tangled in the ligature, the tiny hairs at the nape of the neck which are always too short to be caught up in any pigtails.
Meyer cut the ligature, not because of what was caught in the knot, but because he wanted to preserve the knot for further forensic investigation!
