Self-inflicted or was he murdered

A mansion an imposing old structure
It had been there as long as I could remember
It had seen better times in its heyday
Where socialites were having their way

But sadly it went into bad times
Triggered off by an unfortunate event
That remained still a mystery until this day
What really happened no one could say

A billionaire riding high in his calling
Had made complaints against the owner's dealings
The authorities were deep in sensitive investigations
Which took more time than usual for action

One morning a grim discovery was made
The complainant billionaire was found dead
In a posh bathroom of the mansion
How he eluded security none could fathom

Gunshot wound to his temple from one bullet
Was it self-inflicted or was he murdered
Household staff on leave the owner on vacation
How it happened posed lots of questions
