Yeah, I’m lost myself on what exactly she did to him.
That’s not to say I don’t believe that she killed him (I absolutely do), but this whole thing is incredibly odd (limited time in broad daylight).
I guess it’s possible that she went out and dug a grave on Sunday night, but that may be very difficult, if not impossible.
And it still doesn’t answer the question of how she killed him.
IMO, she didn't dig a grave or leave him for dead. Maybe there was something that happened the night before but I think he was alive when he exited the truck after the 2:15 video. I think she ended his life somewhere nearby and disposed of him in a place that will be found someday, and suprisingly not likely hidden well. Rental cars, accomplices, alternative timelines will all prove futile. She did what she did quickly and in line with what people like her do when they commit that ultimate act of selfishness. It's all so odd right now but I don't think she's that smart and I feel like they'll release the official transcript soon enough.
