Something that's not making sense to me is earlier I was thinking this might've been done to save their reputations. Make it look like an accident. JH and/or SH might not have known about a black box on their vehicle (I didn't know till this case), but they had to know bodies would be autopsied when located. So there would be proof it likely was not an accidental run off a cliff. I'm wondering if whatever they were running from would've cost them more than public humiliation and the kids being taken away, it would've been more like prison for one or both of them?
