It's said to be solved, and the killer is the father of a police officer. The Black Dahlia tragedy killer is the father of former Los Angeles police detective Steve Hodell George Hodell. In 1999, Steve Hodell's father died. While sorting through his father's belongings, he found two photographs. The person in the photos was Elizabeth Ann Short. After investigating, he realized that the murderer who killed Dahlia that year was his father.

The Black Dahlia tragedy is the most famous unsolved case in the United States after World War II.On January 15, 1947, the body of American actress Elizabeth Ann Short was found in a vacant lot at 3800 Norton Street Avenue in Southwest Los Angeles. Short's body had not only been cut off from the waist, but had also been cleaned up and drained of blood. She had a laceration in her mouth, and the coroner showed Short died of shock and hemorrhaging.

The victim, Elizabeth Ann Short, was a lousy actress who liked to wear black dresses and lipstick, hence the name "The Black Dahlia," and the case was called the Black Dahlia tragedy. Until the beginning of the 21st century, the case remained unsolved and became a famous unsolved case in California history. Researchers who had investigated the body said, "The killer cut the body so expertly that only someone with real surgical skill could have done it."

Steve's father happened to be a surgeon. On Short's buttocks there was a shadow drawn with crossed parallel lines, a common technique used by Man Ray and most admired by painter George Hoddle during his lifetime. On top of that, Steve had a note-taking expert authenticate the letter that was handwritten back then, and found that the handwriting was exactly the same as his father's.
