That's what I was wondering too. "9 km along the river" implies the items were scattered is what I'm thinking. Makes me think they were in the boat and it overturned.
Wouldn't the divers have found some items or evidence in the water if they capsized? I believe they said the divers found nothing in the water?
I'm very new but this case has grabbed a hold of me, I think I've read 40 pages of posts. Thanks everyone I love this site!
If the items were all in one location, then that's a different story.
