Well, if a scavenging animal moved the body, it couldn't have moved it THAT far. And if the animal moved the body AFTER the fluids had drained from it... well, there would be a trail of hair and some of that viscous fluid... and the body would have fallen apart, much more than just a missing foot. So I don't think it was moved by an animal. A juror might think so, though.
Sadly, because the jury cannot ask questions directly of the witnesses I suspect they might leap to wrong conclusions.
