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?

"near" would still mean transported.

From the paper http://tinyurl.com/2cvz7h

The abundance of skull and limb bones at this site, as well as at most other
African Plio-Pleistocene archaeological sites, has been interpreted as the result
of: 1) hominids hunting and selectively transporting those parts from complete
carcasses (Isaac, 1978, Isaac, 1983, Isaac, 1984, Bunn, 1982, Bunn, 1983, Bunn,
1991, Bunn and Kroll, 1986, Bunn and Kroll, 1988, Bunn and Ezzo, 1993,
Domínguez-Rodrigo and Pickering, 2003, Domínguez-Rodrigo, 2002, Oliver, 1994,
Rose and Marshall, 1996 and Domínguez-Rodrigo, 1997); 2) hominids transporting
complete skeletons from partially defleshed carcasses (Capaldo, 1995 and Capaldo,
1997); or 3) hominids passively scavenging the brain and marrow-bearing long limb
bones from defleshed carcasses at felid kills (Blumenschine, 1986 and
Blumenschine, 1991).

In some cases, epiphyseal biometry and opposite side elements (work in progress),
together with the high presence of axial elements at FLK Zinj, indicate that
carcasses may occasionally have been transported complete or almost complete, as
Capaldo, 1995 and Capaldo, 1998 suggested.

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 -
