Lenny ODed. Some ODs are suicide but I don’t think in Lenny’s case. He was sprawled out on the floor.
There are photos of the covered gurney in Marilyn’s case and some photos from the morgue, but I don’t think any photos of her on the bed ever came out.
Her autopsy report was published in the sixties though.
Part of the controversy over Marilyn’s death is if the POTUS and AG could have a big Hollywood star whacked (or at least interfere in the investigation of her death and steal her diary), then anyone in America could be “touched”.
