Btw, here is a even more interesting legal entanglement that could happen.
What about life insurance when the mother is killed first by a suicided spouse?

Does the life insurance now go through the husband and his heirs if different than the mother’s will.
Example
1 million life insurance policy.
X kills Z. Does X get the life insurance policy as beneficiary because he lived longer than Z and now it goes to X’s heirs.
I am sure there is something on the books for this one.
Oh and btw, that insurance payout would probably depend if Suicided Murderer had a justifiable excuse for the murder.
It will be a mess if there is any life insurance.
