I think the most likely scenario (if she did move his body), is that she killed him in one location, and left him there.
She then returned, and moved the body (so she would have moved it once).
I’m just trying to make sense of how they were able to actually file the murder charge, as they don’t have his body, and he left that house alive. There likely aren’t any witnesses who can say they saw a murder or his dead body (like the Frazee case).
That’s the only reason that I’m even open to her moving the body, as it would provide this evidence (DNA, and/or decomposition where it shouldn’t be).
