Yes. I live in the Midwest US, and while a 4 hour round trip is not super significant, it would be for a phone charger… but again, like you said, if that was his only means of communication, it makes sense. I think the fact of him driving in the middle of the night for a charger could speak to the significance of his social life… I know Snapchat is very popular w Dylan’s age group, but I think it’s an interesting account for him to have, especially w as much as his parents insist that all he did was work, eat, and sleep. I’m just seems his phone and its portal to the life lived on social media were more important to him than his parents realized, in my opinion.
(And again- all of this is very common for “kids” his age. For parents not to know what’s going on, social media accounts, unknown social life, etc. I just think it’s worth noting because there is likely a whole other side of Dylan which hasn’t become clear yet, and this could certainly lend clues to the investigation.)
