If I recall correctly (and this from 4 decades ago) Velikovsky speculated in one of his books that the body of Nefertiti had been found in a pit not far from Tut’s tomb. He suggested that Nefertiti’s mummy had been dragged from a tomb and tossed into the pit (along with others) by grave robbers. However, I’m not going to go back and reread all of Velikovsky’s books to confirm this hazy memory.
I'm glad you've read some V. He didn't write that. His view about the contents of the pit tomb was that the wife of Smenkhkare had been interred there. One of the things V wrote about Nefertiti is excerpted up there, and the pit burial is discussed in the same book.
