Backinfo from Best Gore member @uzitv:
Kid records himself blowing brains out with gun, video gets uploaded to YouTube titled “1444”. Don’t know what language that is.
In the meantime I acquired a longer version of the video, and it’s also the correct orientation, which now shows clearly that the markings on his t-shirt are in Russian. His name was Gleb Korabljov (Глеб Кораблёв). He was born in September 2001, so at the time of his suicide, he just turned 18. The gun used was apparently a Saiga 12 shotgun.
Thanks a lot for the video, @uzitv:
