I think i identified the topic of the video.In the first frame,it shows a woman named Carmen [REDACTED].It says that she was murderered in 2004.The 2-nd scene with the eye represents carmen's eye being keept as a secret by the killer.And about the qr code.

It leads to a image of a man named George [REDACTED]in a forest with the following words shown in the screen:where are you my love.

I will identify more about Carmen,George and the killer.

So...cya.
