It's been a short enough time that it might be possible to nail down time of death, but not to an exact hour. It's been too long for that. And the body was still found in GA, they would still have jurisdiction over the death investigation. And remember, she was running right before she was last seen, and physical exertion changes ATP levels, which changes the rigor pattern and duration. And if she was put through a compacter, there are going to be postmortem bruises, possibly overlaying or obscuring the lividity pattern. The best we'll get is an estimate, but they may be able to nail it down to within an 8-10 hour span.
