I thought the same thing, MOO. But also, you will note that they appear to have taken evidence from 2 locations. Petito’s death ruled a homicide, experts see Laundrie as abuser. The rock by the water is a different location (a bit down from where she was actually located MOO), which is why I had asked on a previous thread if anyone knew if he crossed the water with her. Only one rock, out of all of those rocks, is marked. They must have something there. Something found either on the rock or in the water near it? Don't know. Speculation and MOO IMO
The crime scene photos really do not give you much of a good picture. I am struggling with them too. The one picture to the left of the rock, you can see behind the tree all those rocks and the stream, so that one fits in. But the others, I wish you an see the ground to get a good picture of what happened. I am still unsure of where they actually found her. The 2 stone crosses confuse me. Your guess about crossing the water can very well be the story! Maybe he tried to get her to a more secluded area? All of it is awful. I hope he is found this week!
