After reading the AA, I've been trying to figure out how the bobcat hits fit in. Here's my guess...possibly the body was in the bobcat briefly at one point (maybe it was part of BM's initial plan). I think this was premeditated well in advance -months even). Possibly...his original plan was to use the bobcat to dump the body in a hole he had dug well before Mother's Day weekend. A sequestered deep hole he could dig at his leisure a little at a time over the course of weeks or months, without anyone noticing. He knew the daughters would be away for Mother's Day weekend and he planned this all in advance.
But, possibly, something happened to throw off BM's plans that night. He darts her, chases her, maybe SM fights back too much. Whatever it was, BM has to rapidly adjust his plan. Freaks out even, multiple frantic trips opening and closing truck doors, gathering incriminating evidence to dispose of, etc. So he removes the body from the bobcat and...?...puts it in his truck? another vehicle? Did the "girlfriend" SD help? Did he use burner phone (now missing) that night to call someone for help?
This is all conjecture and opinion.
