Sounds like an ambulance chaser got to her. Stack’s wife had NOTHING to do with her husband’s actions, and likely she won’t see a dime from any insurance policy he might have had, because as far as I know NONE pay in the event of a suicide.
Some states have laws which have life insurance pay off in the event of suicide, but only after the policy has been in effect for (In North Dakota) two years.
The problem with Stack's wife collecting on the life insurance policy is not one of suicide, but that Stack died in the commission of a criminal act, and that clause is in every life insurance policy I have seen, denying payment.
Old myth.
