blefuscu, What Patsy knew is open for debate, similarly what BR knew is also open for debate. The reason knowledge is distributed rather than shared might be because all three knew what they were engaged in and wished to share as little as possible. Because the R's had a planned flight they had to find JonBenet missing when they did, 9 AM, was too late. The trick in this case is to work out whether Patsy is covering for BR or JR is covering for BR or both? If neither then explain why the parents forensic evidence is found on JonBenet? .
