I went back to early posts, since we sadly are lacking new info.
dbdb11 has said that RT said that the 360 photo BT took while up on the hill that day in their walk included “cars in the parking lot below” and RT was very upset police were not looking into the owners of those cars as “potential suspects”.
So, based on RT’s words, others were there in the general area where RT and BT were. They weren’t alone alone.
I do wonder if LE was able to find and interview these vehicle owners. I hope so. And where is this parking lot? Did we ever have a probable guess on which lot this would be?
Dbdb11’s post where he mentions this:
