Remember, the whole family is hard left so theyre not too inclined to upset the apple cart. More like walk away with a whole lot of money and political favor. I think it was the brother who took control and stopped all communication on the subject. Might want to look how well heeled he is. Lifestyle changes etc.
I was thinking the same thing. How low can you go by not wanting to find the murder of your son because of ideological beliefs. If that’s not the case then they’re being threatened or paid off or all three of the above. Whatever it is it’s kinda scary.
