They, somehow, concluded that the carcass had been transported to this
location. How did they know this? Why could it not have been killed
at or near this location?

New estimates of tooth mark and percussion mark frequencies at the FLK
Zinj site
J Hum Evol. 2005 Dec 30
"Traditional interpretations of hominid carcass acquisition strategies
revolve around the debate over whether early hominids hunted or
scavenged. A popular version of the scavenging scenario is the
carnivore-hominid-carnivore hypothesis, which argues that hominids
acquired animal resources primarily through passive opportunistic
scavenging from felid-defleshed carcasses. Its main empirical support
comes from the analysis of tooth mark frequency and distribution at
the FLK Zinj site reported by Blumenschine (Blumenschine, 1995, J.
Hum. Evol. 29, 21-51), in which it was shown that long bone mid-shafts
exhibited a high frequency of tooth marks, only explainable if felids
had preceded hominids in carcass defleshing. The present work shows
that previous estimates of tooth marks on the FLK Zinj assemblage were
artificially high, since natural biochemical marks were mistaken for
tooth marks. Revised estimates are similar to those obtained in
experiments in which hyenas intervene after humans in bone
modification. Furthermore, analyses of percussion marks, notches, and
breakage patterns provide data which are best interpreted as the
results of hominid activity (hammerstone percussion and marrow
extraction), based on experimentally-derived referential frameworks.
These multiple lines of evidence support previous analyses of cut
marks and their anatomical distribution; all indicate that hominids
had early access to fleshed carcasses that were transported,
processed, and accumulated at the FLK Zinj site."- Hide quoted text -
