I wonder if, at 12:56am, Theo started heading up the road to the lighthouse.
I think a previous post of yours said that if his (or 'a') phone was underneath the tower the signal may have gone low (presumably due to tower height and the tower transmissions being sent outwards over distance).
That's an interesting thought indeed.
From your timeline:
- 00:05 GPS tracing stops
- but the phone continued sending signals till the afternoon of June 1st
- 00:20 sends Messenger message to friend Lou in French about U2 Tour: ugh, in September or something?'
- 00:23 watches YouTube Burger quiz for 1 minute and 50 seconds
- 00:55 sends WA message
- 00:56 ping location point “near town”
- 00:56 sends WA message to stepsister in Belgium of a kiss emoji and 'merci'
- 01:01 Theo's phone zoomed in on the location of his hostel on GM, the phone GPS appears to have still been off because the location of the phone was not recorded
I'm still looping possibilities related to the 7 minutes stop at the Rec Grounds and the apparent hike to Cosy and feel that persons he met during that time are involved.
But if, as you suggest, he did go up the road to the lighthouse then he could have met or been picked up by someone and given a ride somewhere.
That would explain the ping closer to town. And the phone signal at 6am, and 1:42pm later that day.
And it would explain why there's nothing washing up on beaches or being found in the area.
