It actually was a terrible thing to have that commitment ceremony before poor Daniel was buried, but as you said, they probably had their ...reasons...
That was a busy week.
21 Sept - a Death certificate is issued for Daniel ('so she could bury her son'-as reported)
25 Sept - LB says publicly that he is the father
26 Sept - HKS announces on LKL that he is the father
27 Sept - Dr. Wecht announced the findings that Daniel died of a lethal combo of Zoloft, Lexapro, and Methadone
28 Sept - ANK and HKS commitment ceremony
7 Oct - Memorial service held for Daniel Wayne Smith in Mexia Texas. (ANS does not attend)
12 Oct - Virgie goes on Nancy Grace, questions why Daniel has not been laid to rest yet. Speculates that ANS could end up dead and HKS's motive for it.
19 Oct - Daniel Wayne Smith laid to rest
Shoot, I forgot to add. I think that one of their "reasons" was that they weren't sure they were going to be able to stay in the Bahamas. HKS didn't purchase the plots till sometime in Oct.
