There was a real case where a white woman, a movie director, was attacked and strangled in her office apartment, by an illegal alien Hispanic construction worker, and then hanged by him.
Initially, her murder was declared a suicide. Her family fought to have the case reopened, and the murderer was found.
When Law and Order did an episode based on the case, they changed the murderer to the white employer of the illegal alien, who wanted to hide that he was employing illegal labor.
The usual whodunit solution for Law and Order:
who is the most prominent, privileged white character? That’s whodunit.
