Florence Gordon's life came to a tragic and violent end on October 20, 1933, in New York City, New York. She was a woman whose marriage to William L. Johansen, a Danish-born man who would later become a notorious serial killer, had deteriorated into separation and conflict. The couple had two children together, but their relationship had become increasingly troubled.
What happened to Florence that October night would remain concealed behind an incorrect determination of suicide for several years, until her husband's involvement in other murders brought the truth about her death to light.
William Johansen had a troubled history before Florence's murder. Born in Denmark, he immigrated to the United States as a child and eventually settled in New York City. He worked in theaters, restaurants, and other occupations, accumulating a criminal record that included an embezzlement offense for which he received probation. He also reportedly worked in a hospital morgue, where he later claimed to have developed disturbing fascinations involving human bodies. His behavior reportedly became more troubling when he consumed alcohol. These details would take on greater significance after investigators uncovered the extent of his violent crimes.
Around midnight on October 20, 1933, an argument erupted between Florence and Johansen. According to accounts of his later confession, the confrontation escalated when Johansen grabbed Florence by the throat and strangled her until she died. Rather than immediately reporting what had happened, he placed her lifeless body on a bed. He then took a boning knife and cut open her abdomen. Johansen later claimed that Florence had told him she was pregnant and that he wanted to determine whether her statement was true. The resulting scene was exceptionally disturbing, combining a fatal strangulation with postmortem mutilation.
When authorities investigated Florence's death, they reached a conclusion that would allow her killer to escape immediate accountability. Despite the circumstances surrounding her injuries, investigators interpreted the scene as an apparent suicide involving self-inflicted abdominal wounds. The death was reportedly classified as a suicide rather than a homicide. That determination meant Johansen was not immediately arrested or prosecuted for killing his wife. What investigators initially believed to be a self-inflicted death would later emerge as the first known murder attributed to a man who continued killing for years.
Following Florence's death, Johansen left New York and began working as a merchant seaman, traveling between ports and assuming the name Harry W. Gordon. His maritime employment allowed him to move extensively, eventually bringing him to California. Approximately eighteen months after Florence's murder, he was in San Francisco, where another woman would lose her life under similarly violent circumstances.
On April 6, 1935, Johansen encountered Lena Betty Coffin, a woman involved in prostitution, along Market Street in San Francisco. The two went to a hotel, where they registered under assumed names. Once inside their room, Johansen attacked Coffin, strangling her until she was nearly unconscious. He subsequently covered her mouth with tape and stabbed her to death. After the murder, he attempted to eliminate evidence connecting him to the crime, cleaning the room before departing. Coffin's death remained another chapter in his developing pattern of violence.
Johansen subsequently traveled through other parts of the country, including Oregon and Texas, before returning to California. He eventually married Lydia Gordon, who operated a flower shop in Long Beach. While presenting himself as a working sailor and husband, he continued concealing his involvement in the deaths of Florence and Coffin. His apparent ability to maintain an ordinary public existence stood in sharp contrast to the violent conduct he would later acknowledge.
On June 24, 1940, Johansen committed another murder, this time involving Irene McCarthy in San Francisco. He encountered McCarthy at a drinking establishment, and the pair later went to a hotel room. According to accounts of the crime, Johansen strangled McCarthy with an article of her clothing while she was in bed. He then mutilated her remains with a knife. Before leaving the hotel, he attempted to conceal evidence by turning over the bloodstained mattress and cleaning himself. He subsequently traveled to Los Angeles, apparently hoping to avoid identification and arrest.
The investigation into McCarthy's murder ultimately brought Johansen's years of violence to an end. Detectives interviewed witnesses at establishments where the victim and her companion had been seen. Investigators obtained information about the man who had accompanied McCarthy and connected him to an alias he had been using. On July 9, 1940, authorities arrested Johansen in Los Angeles. Hotel employees subsequently identified him as the individual last seen with McCarthy, providing important evidence linking him to the crime.
Following his arrest, Johansen confessed to the murders of Irene McCarthy and Lena Betty Coffin. He also revealed his true identity and acknowledged killing Florence Gordon in New York in 1933. His admission transformed the understanding of Florence's death. What had been classified as suicide was now connected to the confessed actions of a serial murderer. The circumstances Johansen described, including the strangulation and subsequent abdominal mutilation, explained the unusual injuries that had originally contributed to the mistaken conclusion reached by investigators.
Although Johansen admitted responsibility for Florence's murder, the criminal proceedings that ultimately resulted in his execution concerned the two California killings. He was charged with the murders of Coffin and McCarthy rather than being separately prosecuted in New York for Florence's death. The distinction was significant: his confession identified Florence as one of his victims, but the documented convictions were for the later murders.
Johansen's criminal proceedings took place in October 1940. He initially expressed a willingness to plead guilty, but his legal representation pursued a different course. His plea was ultimately changed to not guilty by reason of insanity, placing his mental condition at the center of the proceedings. Johansen openly acknowledged his dangerous impulses and warned that he might kill again if released. His statements reflected an alarming recognition of his own conduct and the threat he presented to others.
The court rejected the insanity defense, finding Johansen legally sane. He was convicted of two counts of first-degree murder in connection with the deaths of Coffin and McCarthy and sentenced to death. The proceedings established his criminal responsibility for those killings, while his confession also left a record of his involvement in Florence's death. Although investigators examined whether he might have been responsible for additional unsolved murders, including cases associated with the Cleveland Torso Murderer, no additional convictions resulted from those suspicions.
On September 5, 1941, William L. Johansen was executed in the gas chamber at San Quentin State Prison in California. His execution came nearly eight years after Florence Gordon was killed in New York. Before his death, he publicly acknowledged having murdered three women and expressed the belief that he could kill again if allowed to remain free. His execution ended any possibility of additional criminal proceedings against him for Florence's murder.
Florence Gordon's case remains particularly disturbing because her killing was initially misunderstood by the very authorities responsible for determining how she died. Her husband's confession, obtained years after her death and following the murders of two additional women, revealed that the circumstances surrounding her injuries were not evidence of suicide but the result of deliberate violence. The initial ruling had allowed Johansen to leave New York without facing a murder prosecution.
Available historical accounts do not establish Florence's exact age at death, her ethnicity, or whether a formal proceeding subsequently corrected the original suicide ruling. They also do not document a separate indictment or conviction specifically for her murder. Nevertheless, Johansen's confession established his acknowledged responsibility, and his eventual convictions and execution brought a measure of legal accountability for the broader series of killings.
Florence's death marked the beginning of a documented sequence of three murders spanning New York and California between 1933 and 1940. Behind the historical record of a serial killer was a family that lost a mother and a woman whose death was not initially recognized for what it was. Although Johansen was ultimately brought to justice for his later crimes, Florence Gordon's story remains a sobering example of how a mistaken death determination can conceal a homicide and delay recognition of a victim's suffering for years.
