I doubt Larry Birkhead will try to have Anna Nicole and Daniel's deaths investigated. Virgie Arthur might. But to do that she will need to have some kind of legal role.
This is Howard Stern's nightmare. Above all, he wants to discredit Virgie Arthur and turn everyone against her.
Daniel turned out to be nice guy. He spent only one day in the Bahamas and he died in the presence of Howard Stern. Unless somebody pushes, there might be a coverup. To even suggest that it is Virgie's fault is ridiculous. But she might well have guilt feelings and thus want to prevent it from happening to Dannielynn.
Sterns really reaching now, (blaming her for he and Anna’s failures), wonder why he is so afraid of grandma?
