Who was the unknown person?

In the Hillside Cemetery, Andover, N.Y.

It's a story that's almost fifty years old, but it has held the attention of
many because it's a case that  has yet to be solved.

It was March 20, 1970, and a man on his way to work, John Billings,
discovered a body along Davis Hill Road in the town of Andover,
N.Y.

The state police were notified and Investigator Robert Jackson was the
first officer at the scene. (Jackson was an Andover resident and lived
maybe only a mile or so from the scene.)

The body was male, heavy set, approx. age of 25 to 40...there were no
identifiable features as both hands and the head had been severed.
It was also reported that there was an X on the man's chest area.

The area was sealed off and the entire area was searched for any possible
clues, but nothing was found that could be tied to the murder.

According to the report, nothing was done to conceal the crime as the
body was lying along the road at a spot where it could have been
tossed over an embankment, but the latter didn't happen.

The body was removed for an autopsy, photographs etc, and with no
identification known, was buried in the Hillside Cemetery in Andover,
N.Y. a few days later with a marker proclaiming "unknown".

I know where the grave is located and had visited it over the years in
my regular course of making other burials after local funerals in and
around Andover.

According to what I have read in the last five to ten years, the State
Police have not closed the file.

I had heard talk within the last five years or so that there was a
possibility that the body might be exhumed to try to obtain a
DNA sample, and try to match it against the national DNA
database.  I doubt very much at this point that that is going to
take place. It would be an expensive situation, and usually the
county or state does not want to invest financially if the result
might prove negative in a positive identification....

So who was this person, presumed murdered in another place,
driven to Andover N.Y. and disposed of.... and why in Andover?

Was it organized crime? Was the dumping of the body in Andover
a 'message' meant for some person or business in Andover?

Too many questions, and really no concrete answers to those
questions. 

The only chance possibly of solving the crime is if someone who
might have been involved all those decades ago would come
forward before their own demise and admit to the crime or
the circumstances surrounding it.
