They sound Spanish to me in the video, so I presume it’s most likely from Mexico. The video shows an unknown Cartel use a tree fork to help behead young man that made confession/statement before death.
He somewhat seems conscious right before the slicing begins. You kinda hear faint breathing, see eyes twitch. Yet he makes no conscious move at all when slashing starts. As if he’d been shot before decapitation.
Props to Best Gore member @seraphim-serenata for the video:
