I've tried to read every single post but have skipped a couple pages when things were moving fast. I didn't see this mentioned, so apologies if it's rehashing a topic.
I've repeatedly listened to the audio released by the ISP immediately after the press conference. I've listened with and without headphones. I heard and still hear "Git down the hill." However I also hear two separate and distinct background noises. One is the crunching of leaves.
But the other sound that has really been bugging me is a rhythmic 'whooshing' noise. It finally just occurred to me last night that it sounds rather similar to the sound when taking blood pressure with a manual cuff & stethoscope. I'm wondering if Libby quickly slipped the phone in her top/bra to hide it while it was still taping and the microphone is picking up her heartbeat? I tried to recreate it using my iPhone video and voice memo app and walking up/down stairs. It picks up my footsteps on the stairs but not my heartbeat. But then I'm not in the same emotional place she was, which at that point could've been adrenaline rushing and fear/panic/sheer terror.
I will note that with my experimenting the video camera recorder picks up more sounds and with more clarity than the voice memo app on my phone.
If Libby's phone was hidden away tucked in her top/bra, that could indicate the phone stayed with her & was recording much longer than if she had opted to go through the motion of reaching for it, taking it out of her top (which he might see, or she wasn't able to do) and her pitching it on the ground at some point along the way. Which could also indicate that BG found it himself, and
he pitched it. (I've felt all along LE has the actual phone. I've also felt she clung to that phone as long as she possibly could. Even if she couldn't use it right away to get help, she'd cling to it in case she did get an opportunity. IOW from a psychological perspective it was a lifeline - a means of connecting to others that when one is in distress they don't want to lose.) All this is MOO.
