On that LKL rerun yesterday he asked Anna if she's still a devout Catholic. She answered "i love the Lord". But if she is a devout Catholic my understanding is that it is ok to cremate someone, but you must bury the ashes. You can't keep them around the house. Altho, that's just what she did with Marshalls ashes. I saw the Anna Nicole show on youtube where she placed Marshalls urn on top of the TV! Right on the edge. It was crazy! On the friggin' TV set! For crying out loud. But maybe with Daniel she would'nt have wanted to cremate him unless his ashes were buried. Altho, as a mother, the thought of cremating her child must've been out of the question.
This is an interview with both ANS and HKS from May 2002.
If you didn't see it, read it. I think it might be rich with opportunity.
Look at the part where HKS is talking about how a guardian was appointed for J. Howard Marshall and the family kept her away from her husband.
