Who Is the Black Dahlia?

In a haunting voice-over, Sergeant Harry Hansen recounts the chilling beginning of a notorious murder case. On January 15, 1947, Hansen and Sergeant Finis Brown were called to investigate a gruesome find—a mutilated, bisected corpse of an unidentified young woman discovered in a vacant lot in Los Angeles. The victim had been carefully sliced in half with surgical precision, and all her blood had been drained from her body, suggesting the involvement of someone with medical or mortuary expertise. This grisly discovery quickly made headlines, capturing the city's and nation’s attention, as reporters franticly sought details about the killer and the victim.

The story flashes back to February 1943, revealing the early life of Elizabeth Short, a young woman from Maine. Elizabeth, played by [Lucie Arnaz], confides in her grandmother that her father had sent her money to come to California with hopes of becoming an actress. Upon arriving, her father, portrayed as a stern man, was initially reluctant about her staying with him but agreed reluctantly if she helped around the house. A voice-over narrates her own written words, expressing her optimism about her budding life in Hollywood and her hope of making it big.

However, her life was far from simple or stable. Elizabeth's father was angry with her frequent late nights and lack of chores, which led her to pack her bags and leave her father's home. She found work at an army base PX, passing herself off as the widow of a war hero, a lie she told her supervisor as she pursued her dream of entering the film industry. She also maintained correspondence with her grandmother, detailing her progress, though her life was marked by secrecy and frequent moves. She remained elusive about her background—always wearing black to symbolize her claimed status as a war widow and to emphasize her mysterious persona.

Back at the police station, Hansen and Brown receive Elizabeth's fingerprints, which they send off to Washington D.C. in hopes of identifying her; they don’t match any local records, but this indicates she may have had a criminal record elsewhere. The case picks up further details when Elizabeth, now 19, is arrested for underage drinking in 1944. Soon, her true identity as Elizabeth Short is uncovered, and she is dubbed the Black Dahlia by a local diner, a nickname that sticks due to her jet-black hair and habit of wearing black clothing.

Public fascination with Elizabeth’s story escalates as more and more people confess to having murdered her—yet none can answer the three critical facts kept from public knowledge, deepening the mystery. The police recover Elizabeth’s belongings from a bus station locker, including a cupie doll with a handwritten message saying, "Love, Doc", black clothes, letters from her grandmother, and a stolen address book listing Miles Harmonder, a wealthy movie theater promoter. These clues reveal she had been living a transient and secretive life, often moving from place to place, never paying rent, and going out every night with different men. At one point, she claimed she was a war widow, a detail that added to her enigmatic persona.

An anonymous phone call to a newspaper editor claiming to be her murderer surfaces, providing details no one else knew, and promising to send a package. When the package arrives, it contains Elizabeth’s Social Security card and other identification, fueling suspicions that the sender was the actual killer—someone who knew her intimately.

Further investigation leads Hansen and Brown to Dr. Wallace Coppin, a hospital intern who admits to drinking with Elizabeth on two occasions and helping her by purchasing the doll she kept as a gift. Elizabeth was the one who wrote "Love, Doc" on it. Witnesses recall her going into the Mayfair Hotel and then leaving, later seen walking away from the hotel carrying her suitcase. She was last seen alive, going into the hotel, then leaving with her belongings, only to be last spotted walking down the sidewalk by a taxi driver. Despite extensive efforts, no one recalls seeing her during her final six days alive, deepening the mystery.

Hansen, reflecting on his 20-year career working on this case, mentions that countless leads were followed, but the killer was never caught. Dr. Coppin's alibi held up during the investigation, and the stolen address book's owner, Miles Harmonder, was later found to have committed suicide. Hansen hints at the possibility that the mysterious package sender could have been Elizabeth's murderer and raises a haunting question to the audience: "If anyone listening knows something about the murder that I don’t know, I need to hear from you." The case remains profoundly unsolved, forever etched into Los Angeles folklore as one of the most infamous cold cases in history.
