After watching the body camera footage I have a somewhat different opinion than I did before I watched it.
There's not one bit of evidence that BL was abusive to Gabby. Not one bruise that any relative saw, no prior police records. BL had lots of time and chances to hit Gabby out of the public's view in that van when she was punching him, but he didn't.
This is what I think and I may be way off....
I think BL flew back to Fl. to get away from Gabby. I think emptying the storage unit was just an excuse. It doesn't make sense he'd fly back just for that. I think once he was there, his parents gave him their advice and suggested he called it quits with her. I think he flew back and told Gabby it was over. It's obvious that that poor girl was already depressed. Lots of change, she had quit her job, her relationship was on the rocks and now she'd have to find a place to live. Shattered dreams with a man she didn't even want to spend one night away from when the cops separated them.
I think they went on a hike and Gabby jumped. BL panicked because he thought LE would point the finger to him seeing as now he had a record of DV. So he fled to Fl. More circumstantial evidence pointing to him. His parents may have felt guilty, because they suggested he broke it off. They also thought he'd be a suspect, the fingers would point to him, so they lawyered up. The lawyer told them to keep quiet, so they are. I know it looks like they are cold and callas, and doing so builds even more circumstantial evidence as in a cover up, but they must know that.
I have a lot of respect for the way Moab PD handled this. AZ. is the same as my state. The one that has the scratches and marks is the victim, and the aggressor goes to jail. No exceptions. I wonder how Gabby's mental health would have been if she ended up in jail. I think they skirted the law, and the redacted audio when they were deciding what to do shows that.
All speculation on my part, I'm thinking out loud, and I may be wrong, but to me, it's the only thing that fits. I know many that are good at covering up and hiding their aggression, but I just don't see it with BL. Yeah, he called her crazy, but I don't think he meant she was really crazy. Many people use that phrase when in reality, they are exaggerating.
