Have been mulling the "what happened" around for a while, reading others' thoughts. Here's what I think FWIW. I do think GP and BL had another argument, likely at the site where she was found. And I think that BL may have shoved her, she fell and her head hit a rock with enough force to cause skull fracture/death. Or, he grabbed her by her hair and jerked her hard enough to break her neck.
Either of these scenarios would be enough to call her death homicide because it would be unlikely she did either to herself. But not enough evidence to say it's murder, because either could have happened with no intent to actually cause harm. And BL on the run because he is sure no one will believe him, which is highly probable.
