Why does everyone here theorize that Lisa was deceased before leaving the house? What if she was injured from a fall that caused severe swelling but no bleeding, and in an attempt to cover up her negligence (intoxicated when an accident could took place) Lisa was removed from the home and passed before being disposed? The dog hit would make more sense next to moms bed if she was wearing clothing when Lisa was disposed of and that's where she undressed to pass out when she got home. JMO
If that was the case, wouldn't DB have had to be in contact with a deceased LI for some length of time? Doesn't it take about 20 minutes post mortem for the compounds the dogs detect to form and and begin to "leak" for lack of a better word? That would put her gone from her home for at least 20 minutes, I would think.
Also, if that is your theory, what are your thoughts on why those 7 items were taken the day of the SW execution? I ask most respectfully, just trying to think along the lines of the theory you suggested. I hadn't really entertained that possiblilty.
