I personally don't think a State Trooper was anywhere around. jMO and I don't think a home owner shot him accidentally. Not in this little town.
I'm close to this geographical area too, and agree with what you've said. No state police in the area usually, or if they are, they are speeding to the scene of a crime or really bad accident and wouldn't be involved.
Local LE is another matter. I can't say that I trust " most" of their decision- making capabilities, shall we say?
When a family acts squirmy, for lack of a better term, they are usually the people who need to be looked at closely...Polygraphs, Luminal testing in and around the house, possibly even cadaver dogs.
If a homeowner in the area accidentally shot him, which I don't think is likely but is possible, they surely would have called 911 to report the accident and get medical help, etc.
If it's a stranger murder, why did they
possibly hide the body? Most of the time, unless there's a serial killer- type sicko involved, the body remains where the killing took place.
One look in the skies should have pinpointed buzzards and so forth in the area, as there are tons around.
