One thing I find particularly unusual about this case is how little information (even the most basic kind) LE have shared with the public. I completely understand they do this (to a degree) in almost every case, in order to protect the integrity of their investigations, but with Joe's case, so little has been revealed that it's almost as though they really are not looking for help from the public, but rather, they already have a good idea as to what happened, who is responsible, and it's just a matter of whether they can get that key piece of information out of the perpetrator(s) and/or find Joe that would lead to an arrest(s).
If it isn't too much trouble (you already know the answer), would anyone care to answer either of the following questions?
1. Have LE identified the most recent/last picture of Joe? Kids his age are taking photos 24/7. I understand that his travel companions have posted some pictures of them from when they visited the Lake Tahoe, Grand Canyon, etc. on their social media pages, but if LE are truly looking for information from the public, wouldn't they normally release a photo of Joe from the day he disappeared, the day before, etc. and say, "This is what he looked like right before he disappeared?"
2. It has been alleged that Joe disappeared in the afternoon of July 23rd. It seems like I have read at one point or another that his two friends left Colorado immediately (the same day or the next), and that Joe's disappearance didn't even come to light until the 26th. Is this something that has been confirmed via MSM reports and/or an insider? Or, if it is a rumor, where did it come from? I don't know anyone that would do that. Personally, I might look for him for an hour or so on my own, but then after that call the police. If this is really what they did, I really would like to know their reason for it. That would be such a strange thing to do.
