What lead is there to support the claim that Danni drove to a closed Shell station to disable her GPS and buy pot?
Where does the "parted ways" come from?
We don't know who or how the GPS stopped pinging, only when and where.
Why DW and Danni's movements are shady:
1. The story we have from DW is not the truth/whole truth (LE says DW may have told him more than he told JDT, the changing details, etc)
2. Danni sitting at the Shell for 20 mins with another car when her GPS stops working is suspicious
3. Her ex-now-roomate is a proven street drug addict and dealer - Danni has been exposed to not only him but his friends and associates
4. According to our locals, that Shell is a known spot for illegal activity
5. DW stating he was worried about her being alone, so went with her. Why worry about her?
6. She was celebrating with friends
7. She and DW were on their way to do something that would only take a short while before meeting friends back at Ollie's around midnight. I do not believe the story that she was accidentally following him to Ollie's.
8. He shows up at Dublin's and takes it upon himself to get her phone and update the friends. This is only reasonable if he was asked to do that, or felt a sense of responsibility for doing it (like them being more than acquaintances).
It is entirely possible that "thing" they went to do was sex, or to return his rental and then he'd ride with her back to Ollie's, but the reason I am working through the drug angle is to see how many holes we can poke in it, and because it potentially places people in the scene at the Shell who would have a reason to disable Danni and her GPS.
ETA: We know Danni uses marijuana. There should be nothing to hide about that - it just happens to be illegal in Alabama and require exchanges in less than favourable places if you can't arrange to meet at a normal place or are not on normal place terms with the connect.
