This is not a DNA case. A carefull analysis of the autopsy report is enough to solve the case. It tells us among other things that: 1. JB´s skull fracture was an accident 2. JB bled internally which means she was alive after the skull fracture, probably in a coma 3. JB died of strangulation 4. JB´s body was in rigor mortis when found at about 1:00 PM, meaning that she died at least 8-10 hours before she was found. This would put the TOD at about 4-5:00 AM. If a prosecutor concentrates on solving the case using the autopsy report and not DNA, it will become apparent that the crime was an inside job thus eliminating an intruder.
