^^^doesn't mean it would not happen. Women often blame the other woman, just as men may go after the man his wife is cheating with.
There are just too many millions of places to hide bodies, in any state or county. Only sheer luck, or very specific pings will lead to Heather, IMO.
Have to disagree with the millions of places, cluciano63. If HE is deceased, the body disposal location will likely be in an desolate area the perp/s are familiar with, imo. Hopefully with the info gathered during the investigation; phone pings, interviews, eyewitness accounts, cyber forensics, search areas ruled out, etc. This location can be narrowed down by investigators..
