Here's why:
* Privacy and Respect: Taking photos of a deceased person in their casket is generally considered disrespectful and an invasion of privacy. It is highly unlikely that anyone involved in the funeral arrangements would have allowed such a thing.
* Publicity and Controversy: Such photos would be incredibly sensitive and could cause significant backlash. The public's interest in Monroe's life and death is intense, but exploiting her in this way would be highly unethical.
* No Official Records: No known official records or publicly available sources mention such photographs.
* Security: Security measures would be in place during a funeral, and unauthorized photography would be strictly prohibited.
While it's impossible to say definitively that no photos exist, the factors mentioned above make it highly improbable. If such photos were ever taken, they would likely remain private and never be released to the public.
