I had a distant relative murdered and that is what the family did. They concerned themselves with raising her 3 kids. They would not give interviews and they quietly went about their business and let the police do their job. I think that anything they did that would remind them of the way she was taken from her family was just too painful. It was not that they did not care far from it, they just did not see how getting in front of a throng of tv cameras would help and it was just too painful. Yes, there is a general reaction that can be expected when something like this happens, but not everyone will react in the exact same way. Also, they were such a private family before this happend I think they thought there was no reason to start living in the spotlight. I cannot blame them. I think I would be inclined to lay low and even move away. I would not be able to deal with it.
