I think so many of the cases we follow here leave us wondering why. Why did Scott Peterson kill Laci? Why did Jody Arias kill Travis Alexander? For me, the part of this particular crime that was most difficult was to think that Diane could possibly have committed suicide by vehicle along with murdering her own and her brother's children. If she had been by herself, well, that would have been different. But this woman was chugging out of an open bottle that was right there in the car on the floor of the passenger seat. That is criminal behavior. And she was high on pot. So, she knowingly was committing criminal behaviors by getting high and driving and by drinking AS she was driving. And not drinking a little bit. Drinking a LOT. As a mother and grandmother, I still have a hard time wrapping my head around this one.
