There are numerious scenarios for where he or they could be. The Omega vault is one, locked away in some hidden chamber beneath the Imperial Palace, they could be wandering throughout the fringes of the galaxy for all we know. Although knowing Russ he is very thorough when completing a task so I figure at least one of them is death considering he can be overzealous. Wouldn't necessarily call him overzealous, just takes his job very seriously. He didn't intend to destroy Prospero, it was when Horus told him that was his orders that he did it, and even then he tried to get Magnus to surrender by talking to what he believed to be a spy linked psychically to Magnus and come peacefully with him back to Terra.

If he killed one of them, which at this point is pretty much spelled out in a lot of novels, then he did it on orders of the Emperor.
