How would you know?

THE ENEMIES AND TARGET OF MY
FATHERS LIVE CAME INTO OUR HOUSE IN THE NAME RIOT AND WAR ONLY TO GET
MY FATHER DR SAMMAN KILLED  AND WHEN MY MOTHER RECOGNIZE THE FACE OF
THE KILLER  AND MENTION HIS NAME THAT THEY IMMEDIATELY SHOT MY MOTHER
TO DEATH WITH 3 THREE OF MY BROTHERS SET THE WHOLE HOUSE ABLAZE.

Here’s the flaw in the logic.  If this really did happen (and we all know it’s completely made up) then how would she know this is how it happened?  It’s not as if she was on the internet talking to someone at the time.
