But in all due respect, I had taken part in a 1940s project last taon and I was the one in charge of the famous births, deaths, and murders. It was awesome. =w=
I know a lot about the Black Dahlia murder because of the project

I'm pretty sure there was a movie awhile back sa pamamagitan ng the same title. Something about a young woman who's mouth was slit. Her name was Elizabeth Short. She got the nickname(The Black Dahlia) from the newspaper who printed her story. (Apparently they liked nicknaming cases they found particularly colorful.)

I don't have all the answers, but here's where you can read madami about it: link

Well I believe it was the nickname of an actress, Elizabeth Short, who was brutally murdered in the forties.
