That's hardly your fault. That's how his family treated him. That's why he was murdered. Note that the first time that they saw him after the 'break' he requested was not to check in on his health, or for a celebration of his new marriage, but for (more) money talk. I don't remember hearing anything about his children giving him and Fontelle wedding presents. (Hard to imagine that Bob would have made the same omission regarding the marriages of P, R, J, and A.)
Still, no reward. Not even a humble one. I've seen families who have nowhere near the resources of the (middle-aged) Harrod children put together some generous rewards in other cases. But let's just imagine that they are all 'extremely frugal'. If that's the case, then why not hold a vigil? The media outlets that covered Bob (and Fontelle's) stories would cover it. The monetary costs would be minuscule. Bob's daughters appear to be 'retired' -- surely they have time to devote to it. So, why has it never happened?
I know -- it's a stupid question. It's for the same reason we've never heard about any of them -- daughter J, SiL J, or A -- taking or passing a polygraph. It's for the same reason they point fingers at cleared people. It's for the same reason that they have not availed themselves of the resources (e.g., media) that virtually all families of missing people do. It has to be bloody obvious to the PPD that some of Bob's loathsome children are directly involved in his murder, and likely all of them have been accessories after the fact.
I think that the character assassination that the daughters orchestrated after July 2009 likely tells us a lot about them than it could ever tell us about Bob -- pretty much every aspersion they cast about him reflects their own actions (or inaction) since he was killed. Stingy? How about 'no reward'. Bob didn't care enough about Georgia? His actions revealed infinitely more love towards his wife than his daughters' actions following his disappearance. 'Secretive'? His daughters do not appear to be cooperating with the police, nor using the media.
As frustrating as all of this is for those of us who seek justice, at the very least we have the potential for many wrongs to be addressed here: three daughters stripped of their inheritance ('blood money' comes to mind), spending the remainder of their retirement in prison. Perhaps A and SiL J will be in the same facility as well? How nice it would be for them.
