After that, his strength failed him, and he collapsed to the ground, like Duncan the First.

Based on this, it is logical to assume that the emphasis is on who the killer is, rather than the method of the murder. Excluding a real historical figure, who presumably died in battle, leaves us with a Shakespearean character. And from there, everything becomes clear. If Macbeth killed Duncan, then the profile of Nefertiti's killer is related to him. All that remains is to find this connection.
