Should this death be questioned?

C. Ann's husband made minimum wage so they both worked.
She came into a large sum of money from an insurance claim
due to a back injury at her job. With this money she bought 
many acres of land in her rural county. She also bought a 
small business for her husband and herself.  The years went
past when she suspected her husband was cheating on her 
with one of the employee's.   She confided in a friend and a 
family member her concerns and  suspicions and evidence 
of an affair.  The employee was discharged or quit.  After 
nearly thirty years of marriage the couple quietly separated
and the husband moved into another house on the same
property.  After four years of separation, the husband asked
for a divorce.  Ann too felt she needed to make a fresh start
and agreed to the divorce. She spoke often to her friend
that the affair with the employee was ongoing. She felt they
were going to go public with their relationship since he had
never wanted a divorce till now. ( The former employee
was married also.) Due to her back injury which had
become worse as she got older she asked that he give her
monthly alimony until she got her disability. She also wanted
a lump settlement of half  the property and business. He in
turn would keep the property, business, and homes.  They
argued over the alimony but in emails to her friend she
stated that she had "stuck to her guns on this issue" and
"boy, was he mad"  The divorce was filed and she made
plans to move and buy a home with her part of the money.
She was to receive $50,000 on Thursday to pay down on 
the home she was going to buy. All agreements were to
be signed with his lawyer on Thursday also. 

On Monday

Calls recorded on call wave were upbeat and cheerful
stating she was excited and anxious to get moved and
make a fresh start. The last call on the friends call-wave
stated, " going to bed, will call you tomorrow" (Tuesday)

The next call the following day was to report that C. Ann
had died that day. Family members immediately asked
for an autopsy to be preformed to determine the cause of
death as she was home alone when she died.  The law said
"only her husband could do that, and he did not want an
autopsy" No one would listen to family members or friends.
"Case Closed"
C. Ann was buried as a grieving husband cried at her grave.

A few weeks later he married the former employee.
He had the insurance money from Ann's  death, the
homes, property and the business. It was all his now.
due to C. Ann's death, he did not have to share or pay
alimony.  How lucky can you get two days before a
settlement.

Odd too, was that the former employee's husband had
a fatal heart attack two months before C. Ann.

Both deaths were listed as heart attacks and both lived in
Lewis County, TN.

The citizens never gave these deaths a second 
 thought. nor did the good sheriff or elected officials.
even though family members tried to tell them.
