Well, it has leaked out they had a big falling out after the funeral, so I can imagine that Moe, who made a point of traveling with ANS from the morgue to the airport to the church was stunned to walk in and find HKS had turned it into a circus. Who know, he may have disliked the statement HKS made at the funeral as well... but HKS's greed may have done him in if Moe spills all he knows.
I was really hoping Moe was embarrassed to be photographed all over creation holding the urn of J. Howard Marshall II's ashes - but nobody ever mentioned it!
