I've been browsing this forum for a while, but your post made me sign up to tell my story. After reading a lot of the analysis on the forum and elsewhere for years, about events like Sandy Hook, Boston Marathon, Pulse etc. my first reaction (like everyone else here) was also “not another hoax”.
The next day, however, I got a voice message from a friend of mine. Some background: we went to high school (grades 10-12) together, were somewhat close, lost contact after, and then this year in March he sent me a message on Facebook to reconnect, and since then we've been meeting every couple of weeks to discuss current events (we have similar political orientations but I've never discussed hoaxes with him). He is a flight attendant (Lufthansa/Eurowings) on long distance flights (we are both German, and both live in Germany). This summer I was on a flight with him to Vegas (so I have seen with my own eyes that he's actually a flight attendant).
In his message, he said that he was very unsettled because he was scheduled to fly to Las Vegas and had planned to attend the concert with his crew, but he was at my apartment when he called in sick due to a cold (he looked somewhat sick when he was here). When I called him back he told me his colleagues were all at Harvest 91 and one of them actually got shot. He said the shot colleague was recuperating in a hospital in Vegas along with one other cabin crew member, while the rest flew back. If I remember correctly, she told him she was shot in the lung and will no longer be able to work as a flight attendant because she will have trouble breathing (decreased lung capacity or something like that).
I am meeting him tomorrow, and I'll try to ask him some questions about his colleague while trying not to appear too insensitive. I'll also ask him if his coworker sent him any pictures of herself in the hospital. If anyone is interested (and if anyone speaks German) I can upload the voice message he sent me.
Quite frankly, I'm now at a loss as to what to believe. Either he is lying (possible, is it really a coincidence that he decided to reconnect with me a couple of months before my first ever flight to the states?), his coworkers replied to a craigslist ad and are lying to him (also possible, who would openly admit that they are part of a hoax?), or people did get shot but not necessarily by Stephen Paddock or even from the Mandalay.
I'll keep you guys posted with what I learn when I talk to him tomorrow.
On another note, a different guy I went to high school with (but never talked to) marked himself safe on Facebook with just the caption "angeschossen" (shot at; shot but not killed). That's very suspicious; if you were shot, couldn't you at least muster up a few more words like "Thank god I'm alive" or something like that? He had to have been in Vegas at the time though, or else he couldn't have marked himself safe right?
