There are two knives relevant to this case- Burke's Swiss Army knife found in the basement on a counter and the paring knife found on the counter of the 2nd floor laundry area just outside of JonBenet's room. First off, I want to say that I think that both John and Patsy were involved in what happened that night. So, having said that, this is what I think transpired. While they were in the basement, John told Patsy he needed a knife to cut the cord. Patsy goes up to the kitchen, retrieves the paring knife, and brings it downstairs to cut the cord. The ends are frayed which, imo, means that it was cut with something not conducive to cutting such material. At some point, one of them decides that another knife needs to be used on the duct tape. Patsy goes back upstairs, bringing the paring knife with her. She goes into JonBenet's room to gather some items and places the paring knife on JonBenet's bed. In doing so, fibers from the cord are then transferred to the sheets and she may have even wiped the knife on the sheets. She brings everything to the laundry area and sets the paring knife on the counter. Then she opens up the cabinet with the package of Pull-ups inside, pulls out the Pull-ups just far enough so she can reach back and obtain Burke's Swiss army knife which LHP has hidden inside. The paring knife is left on the counter and the Swiss army knife and the other items are brought down to the basement. Does this scenario make any sense?
