The autopsy of Lyudmila (found on this site) states she was not sexually active.
Thank you for the correction. It's difficult to "hold" everything in memory about this. The fact that she wasn't sexually active doesn't mean that she didn't have an enemy for different reasons. If it wasn't her then I'm reasonably convinced that somebody in that group did. She was the most argumentative and kept saying that "something would get better in a few days" - but we don't know what that is/was.
Given everything they were carrying then a rifle and a few rounds doesn't represent much extra weight. But it would need to be at the ready (i.e. not rolled up inside the tent or whatever). And no rifle is visible in any of the photos. Is there a reason why they would need to secret such a weapon (from the outside world or perhaps each other)? I sincerely promise that I'm trying to get/keep up to speed on everything that is related to this. I'm not doing a very good job though - I will admit. The photo by this site owner shows a rifle but that wasn't this trip - was it? (really sorry : I have a day job too).
I think if we had answers to all of the questions then we might collectively shrug our shoulders and say : "oh - is that it then?". You know : an anticlimax - as these things often are. Then we can move on to MH370 (NO CHANCE).
