1. is there any more information about this than is contained in the link?
I'm asking because the comments after the story are filled with cries for justice and retribution, but the article suggests that at least presently the case is not being treated as a homicide, and it gives no information about the cause of death. Obviously I haven't heard anything about these girls previously. It must be awful for their families.
The girls had been missing from their Iowa home, after failing to return from a bike ride. It was very uncharacteristic of them to not return. Also, there was some question of drug activity in and around their homes.
