If they really thought it was foul play,
and were relatively sure, they would not be checking out other states. When the looked for Hoffa, they dug things up.
Interestingly, in other cases, they have been a bit more open including discussing murder. They may say, **We rule nothing out,**
but they look at things. Cindy Song is an example from the same county. They are matching up DNA and talk about that; it is because they think she is dead. In RFG's case, they are looking at sightings. That does not rule out murder, but that isn't the focus. It doesn't mean they are right.
Now, why are suddenly three stories in one day, with nothing new, except for that tidbit?
