I was playing on the server: DayZ Namalsk (vanilla) EU 3995 (IP: 195.82.158.114)
The time was 06:08 (GMT) and I was at the BK-L01 facility when there were only 2 other people on the server. I was climbing up the stairs to get to the roof (interior) when I was shot twice in the back and killed. Usualkly a pretty normal scenario, right? This time all the door to the facility were lcoked and nobody else was inside. Then out of the blue this player kills me. I have video footage of this happening and can provide it if need be, but you should be able to check the server logs on this one as I have given you the server and the time.
