I've been in a bunch of threads where family was allowed to be sleuthed. Mackenzie Cowell. Shantina Smiley (which wasn't even a murder.) In both cases family (including boyfriends) were definitely sleuthed.
Lack of phone use was discussed already, many many threads ago. The phone not working has also already been discussed. All with very plausible reasons as to how this could happen without MR being a murderer.
Dylan taking his stuff would point towards him trying to hitchhike rather than fish. Which fits in with (a) that he was known to hitchhike, (b) that he wanted to visit his friends, and (c) other cases where children vanished in similar circumstances.
I'm taking a vacation from this thread. A lot of this information has been repeated time and time again, the choice to ignore it is not mine.
