Killed a player, body still stands. Hacking? Bug?

[Mattix90 10]

I was playing with may friend the other day, it was getting dark and there were only few people left on a server so we decided it is relatively safe to go to Stary and try to loot military tents without being sniped. As we approached the tents from the west we've heard the shots. We decided to split up - my friend approached him up front communicating via chat that we do not seek any trouble, I went to the top of that big hangar with my DMR in case my friend fails to resolve this situation without violence. Ofc the second he noticed my friend he started shooting. Then there was some chaos, I was trying to snipe him down and was not sure what happened. The end game is he just ran into the very same hangar I was in. I applied two rounds to his head, then when I saw he was still standing I tried another one... and another one. Nothing happened, he just froze up in one place, there was no massage indicating he died nor did I get any murder/bandit killed. I approached a guy and found out we can loot his backpack as well as his body. He was equipped pretty well - GPS, NVG, Rangefinder, Coyote as well as Mk48, we looted him and bailed cause this situation was getting really suspicious. The same night I went back to Stary only to find his standing body right where we left him as well as about 10 copies of himself somewhere near the tents, all fully equipped with his original gear and all fully lootable. Can anyone tell me what happened there? Did I kill a scripter/hacker, server admin, or was this just some kind of bug?
