Known to the Jazz Age press as “The Broadway Butterfly,” Dorothy “Dot” King was a vivacious 29-year-old model, dancer, and aspiring actress who lived a life of conspicuous glamour. Born Anna Marie Keenan to a poor family in upper Manhattan, she transformed herself after a brief, early marriage. With deep blue eyes, a buxom figure, and bobbed blonde hair, she became a fixture of New York’s Roaring Twenties nightlife, flitting between cabarets and speakeasies, draped in jewels and furs. Her circle included wealthy admirers, stage-door johnnies, and shadowy underworld figures. While some, including her own mother, disapproved of her lifestyle, her maid and confidante, Ella Bradford, remembered her as a generous and caring woman in a world of stark social divides.
On the morning of March 15, 1923, Dorothy’s life came to a brutal end inside her stylish fifth-floor apartment at 144 West 57th Street, just east of Carnegie Hall.
Around 11:30 a.m., her maid, Ella, let herself in and found Dorothy in bed, clad only in a yellow silk chemise. At first, she appeared to be asleep, her head half-buried in a pillow with one arm dangling off the bed. But when Ella touched her mistress’s foot, it was cold. The bedroom window was wide open on one of the coldest mornings of the month. Turning the body over, Ella discovered dark abrasions around Dorothy’s mouth and nose. An autopsy would later confirm she had been murdered, poisoned with chloroform. The disheveled state of the bedsheets indicated a struggle had taken place.
The New York Police Department investigation, led by detectives including Arthur A. Carey, quickly determined that this was a homicide committed during a robbery. The apartment had been looted of valuables, including an estimated $15,000 in jewelry, an ermine fur coat, a suitcase, and cash. The killer had left few clues. A search for fingerprints yielded nothing. Investigators found an empty chloroform bottle in the bed, pieces of absorbent cotton, and a man’s small comb that appeared to have fallen from a pocket. A pair of large, yellow men's pajamas was found stuffed under a couch. The telephone had been moved from the nightstand to another room, suggesting the perpetrator may not have intended to kill Dorothy, but only to render her unconscious to commit the theft.
The case became a media sensation, captivating the nation with its lurid details of high society, secret lovers, and Prohibition-era crime. The press revealed Dorothy’s relationships with several men, two of whom became the focus of the investigation. One was John Kearsley Mitchell III, a wealthy and married Philadelphia socialite who showered Dorothy with gifts and wrote her passionate love letters. He was known to visit her under the pseudonym "Mr. Marshall." The other main person of interest was Albert Guimares, a Puerto Rican grifter described as a lothario, who was also known to be one of Dorothy's lovers and had a history of violence.
Despite intense scrutiny and public fascination, police were unable to build a case against either man or any other suspect. Mitchell was handled delicately by investigators, likely due to his social standing, while Guimares was more aggressively pursued but had an alibi. Detective Carey later wrote in his memoirs that he believed a professional thief, unknown to Dorothy, was responsible. He theorized the killer gained her trust to enter the apartment, used chloroform to subdue her, and accidentally administered a fatal dose while robbing her.
The murder of the “Broadway Butterfly” exposed the era’s deep-seated corruption, class prejudice, and power dynamics. The story inspired books and films, including S. S. Van Dine’s fictionalized 1927 novel *The Canary Murder Case*. Over the decades, the tale has become a cornerstone of New York City lore, a symbol of the Jazz Age’s glittering excesses and dark underbelly. As of August 2023, more than a century after Dorothy King was found dead in her bed, her murder remains officially unsolved. No one has ever been brought to justice for ending the life of the girl who, as one reporter wrote, “lived on the bubbles of life.”
