What are you wanting to do?
If pKiller is an NPC than it cannot be typecast to both a player and an NPC.
The player typecast will return NULL.
I think you want something like this
If( pKiller->IsNPC() )
{
CAI_BaseNPC *pNPC = dynamic_cast<CAI_BaseNPC *>(pKiller);
CHL2MP_Player *pMaster = NULL;
If(pNPC->LikesMaster())
pMaster = pNPC->GetMasterPlayer();
}
So now if pMaster is not NULL than you know that the npc likes his master
and that he had a valid master pointer.

But the information I'm trying to pull is actually a player...it's just
the owner of this particular NPC...:S
