The man who filmed a video that appeared to depict gunshots being fired in the immediate aftermath of the Polish plane crash has apparently been stabbed to death in what many are claiming was a deliberate assassination to silence the individual from making public whatever it was he saw.
The following translation appears on numerous websites, with this Polish website  being the original source.
Film, który zepewne już wszyscy widzeli, autor
tego filmu Adrij Mendierej , któremu wbito noż w
okolicach Kijowa 15 Kw.2010 roku został
przewieżony w tragicznym stanie do szpitala w
Kijowie , gdzie 16 kwietnia dwóch nieznanych ludzi
odłączyło mu respirator. J po raz kolejny wbito mu
3 razy nóż. Andrij zmarł po południu o15.03 czasu
Moskiewskiego 16 kwietnia 2010 roku. Ale
oczywiście jest to przypadek wg ROSYJSKIEGO RZĄDU
The translation is roughly as follows.
“Author of the video seen by everyone by now has been stabbed near Kijow on 4.15 and transported in critical condition to the hospital in Kijow. On 4.16 three unidentified individuals unplugged him from life support system and stabbed him 3 more times. Andrij was prenounced dead that afternoon. Russian government claims it was a coincidence. ”
The video, which can be viewed below, as well as the apparent fate of the man who shot the footage, have not been reported on by any mainstream news outlet, and the story cannot be completely verified, although the footage in the clip is very similar to images and video seen after the crash.
However, some people are of the belief that the entire story is a hoax, and is being used to falsely implicate Russia in the crash of the aircraft. Until any confirmation is forthcoming, its authenticity is still up in the air.
