Here is my alternate theory concerning the JBR murder. I supply it because I am unsatisfied with all of the conventional theories which I have read on this forum and others. I first want to say that this theory may not be shared by many if any people on this forum, but it is a theory and as a theory it is worthy of being explored. The elements of my theory are these: 1. JR and PR did not murder their daughter but they know who did. 2. BR did not murder his sister. 3. A non-R murdered JB. 4. JR and PR are covering up for the murderer of their daughter for a reason. 5. No secret intruder snuck into or broke into the R house to murder JB. This is the foundation of my theory. How does it fit what we know of the facts of the case?
