Is that some sort of hack?

So I was on Woods and I snipe some heavily geared player (airframe so probably a high-level one) who happened to have a teammate. I decided to camp the body from far away but I got a server disconnection 10 seconds after my kill (which I didn't get the last 2 hours I've been playing) and after reconnecting, the body was looted. Since they were high level players, I doubt the teammate would have gone for the body right away...

I just found it strange, is that some sort of hacks? Thanks
