I think it's really important for us not to have assumptions incorrectly so I'll list a some here that need clearing up:
1) Multiple hikers have discussed MH saying he had a sister. Since it isn't just 1 or 2, then he's most likely to have said that. From saying it, we can either believe him or think he's telling lies. If he's telling such a fundamental lie then we can't really believe a single thing he says which leaves us at almost nothing! We can't say he's lying about a sister but truthful about living in New York or truthful about being in IT. To dismiss him having a sister after saying he has one to multiple people means you must not consider anything he said as truth and only go by what can be proven that he did and credible people have witnessed.
2) If he had a sister then at least one hiker has discussed him saying he stayed (not visited) with her before the FT hike. There is a question about whether that hiker's account is credible though so I would suggest we need to find out whether other hikers said he stayed with her or not.
3) There seems to be some different interpretation about his health. Definitely some hikers have said he wanted to do these hikes while he could. Some people, possibly even some hikers, have assumed that meant he was dying. I would suggest we need to find out what all of these hikers actually discussed that he said about that. Did he just say do these hikes while he could, possibly just meaning he's getting older and you never know or, did he actually say anything about dying or having very bad health issues? Maybe he just meant his knees were going to get too bad to be able to do it.
4) The police have said they believe he had been living in the Lake George area just before the hikes. Why are they saying this? Why won't they tell people why they believe this? If people knew, they would be able to judge whether it is a possibility, probable or for sure.
5) There should not be the assumption that, just because the police and us have not identified him that he hasn't been identified by anyone such as his sister. There can be reasons why people have identified him but haven't come forward to say so.
6) Two hikers together stayed where MH was on July 3, 20 days before he was found. Only, it's a huge area that was an air strip. They created a video that included some footage of that camp, although not MH or his tent. We know they stayed overnight but they could have been hundreds of feet away most of the time, they could have been in their tent most of the time and they could have been sleeping most of the time. Until they say they were 50 ft away from MH's tent for 5 hours, it can't be assumed that he had a 5 hour opportunity to reach out to them. He could have been asleep when they were near and, when they were further away, they were too far for him to hear them.
Note that I'm not trying to assume anything here. If someone can say otherwise to what's above then great, we can clear that up! I'm just suggesting we get these confusions sorted out because I think we can. I will try to contribute by further researching some of these points.
Now I'm going to try to find these official podcasts spoken about. There is so much info on this case in internetland, someone can always help point me to these and any other fundamental and good information that should be seen. We should actually make some kind of sticky post with a list of it. Maybe there is but I don't know about it!
It's great but some of the dates are different from other timelines I've seen and some just have a month and year whereas some other timelines give a date. So, it would be nice if that photo timeline could be updated if need be.
