She said "video has emerged of what we believe is SS dumping her limp body".
I'm not a NG fan. It's IMO that she embellishes facts/things. With that said, the first thing I did was check the timestamp on the video you posted to see if it was old new since she said "video has emerged" like it's new news. The video is fairly recent so I had to scratch it being "old news" she's reporting about off my list.
What I'm guessing, since we all know he was caught on camera from page 36 of 896: "and proceeded to carry what appeared to be a limp body to the trunk of the vehicle", is that NG is either way behind all of us, or she didn't mean actually dumping her body in the trees where she was found. She could have been clearer and said WHERE he was seen dumping her body.
Unless I see it from a more (IMO) legitimate source, and someone that doesn't stretch the truth for gasps and clicks (again, IMO)... I gonna think she's talking about when he moved her to the trunk. Until then.. I'm firm in what I believe. lol
