no one has seen that video before. the mutilations are also very similar. chances are, either the person that did it posted it or someone they know. that is how these videos get out.
its also been confirmed luka e-mailed the video personally to theync and bestgore the same morning, immediately after filming/editing. and the original description is by him.
in one of the packages was a note saying there would be 6 packages. probably head and genitals left.
i say the head to his parents, genitals to a church.
