Jane Toppan looked like the kind of person families could trust.
Known for her cheerful personality and friendly bedside manner, the Massachusetts nurse became known as “Jolly Jane.” Patients and families welcomed her into their homes during some of the most vulnerable moments of their lives.
Behind that pleasant exterior, however, was a woman who would eventually confess to murdering dozens of people.
Toppan admitted to killing 31 people, many of them patients under her care. She was eventually arrested in 1901 and put on trial for murder. Rather than being sent to prison, she was found not guilty by reason of insanity and committed to a psychiatric institution for the remainder of her life.
Her case became one of the most disturbing examples of a caregiver using a position of trust to commit murder.
Who Was Jane Toppan?
Jane Toppan was an American nurse and serial killer who operated primarily in Massachusetts during the late 19th and early 20th centuries.
She was born Honora Kelley in Boston in 1854. After her mother's death, her father surrendered Honora and her sister to the Boston Female Asylum. As a child, Honora was later placed with the Toppan family in Lowell, Massachusetts. Although she was never formally adopted, she eventually took the Toppan surname.
As an adult, Toppan entered the nursing profession.
That career would ultimately give her access to exactly the type of people she wanted to target: elderly, sick and otherwise vulnerable patients.
Today, she is remembered as Jane Toppan, the serial killer nurse, and her case remains one of the most notorious examples of a female serial killer operating within the medical profession.
Why Was Jane Toppan Called “Jolly Jane”?
The nickname “Jolly Jane” sounds almost harmless considering the crimes that would later be associated with it.
Toppan was reportedly outgoing, cheerful and friendly. Her pleasant personality helped her establish relationships with patients and the families who employed her.
That contrast between her public personality and her crimes became one of the most disturbing aspects of the case.
She was not an obviously threatening figure.
She was a nurse.
People trusted her to care for sick relatives.
That trust gave her an enormous advantage.
Jane Toppan’s Nursing Career
Toppan began her nursing training in Massachusetts during the 1880s. She worked at Cambridge Hospital and subsequently took positions providing private nursing care.
Her time working around patients also appears to have been when her fascination with drugs and death developed.
Historical accounts state that Toppan experimented with morphine and atropine on patients. At the time, medical knowledge and oversight were considerably different from modern standards, and unexplained deaths among elderly or seriously ill patients were not always treated as evidence of murder.
This environment allowed Toppan to exploit her position.
She had access to vulnerable patients, medical drugs and homes where she could work with relatively little supervision.
Eventually, concerns about her handling of drugs contributed to problems in her nursing career. She later found work as a private-duty nurse, where she continued caring for patients in their homes.
When Did Jane Toppan Start Killing?
Determining exactly when Jane Toppan began murdering is difficult.
Toppan later confessed to murders dating back years, but not every killing she claimed could be independently verified.
Guinness World Records states that her nursing career began in 1885 and ended with her arrest in 1901, and that she confessed to killing 31 people during that period.
Some of the deaths attributed to her occurred while she was working as a nurse. Others involved people who were personally connected to her.
This distinction is important because the number of people Toppan confessed to killing is not the same thing as the number of murders that were conclusively established through the evidence available to investigators.
How Did Jane Toppan Kill Her Victims?
Jane Toppan's murders were primarily associated with poisoning.
She used drugs including morphine and atropine, exploiting her knowledge and access as a nurse. Historical accounts describe her administering drugs to patients and observing their reactions.
The combination was particularly significant because atropine could mask one of the recognizable effects associated with morphine poisoning.
This helped make her crimes more difficult to identify at the time.
Toppan's victims were often already sick or elderly, meaning that a death could initially appear to have been caused by natural illness.
That made her profession an ideal cover for murder.
Jane Toppan’s Victims
The victims associated with Toppan include patients, acquaintances and members of families with whom she had connections.
Among the people she identified as victims were:
Israel Dunham
Lovely Dunham
Elizabeth Brigham
Mary McNear
Florence Calkins
William Ingraham
Sarah “Myra” Connors
Edna Bannister
Mattie Davis
Genevieve “Annie” Gordon
Alden Davis
Mary “Minnie” Gibbs
These identified victims span several years and included people who had trusted Toppan as a nurse or caregiver.
The deaths of several members of the Davis family would ultimately become the turning point in the investigation.
The Davis Family Murders
The murders of the Davis family were among the crimes that finally brought serious attention to Jane Toppan.
In 1901, Mattie Davis became ill while Toppan was caring for her. Mattie subsequently died.
Toppan then remained connected to the Davis household and cared for other members of the family.
Soon, more deaths followed.
Alden Davis died, followed by two of his daughters, Genevieve Gordon and Mary “Minnie” Gibbs. The succession of deaths was suspicious enough to attract attention from surviving relatives and investigators.
Minnie Gibbs' husband became suspicious and pushed for an investigation.
Her body was exhumed.
The examination revealed evidence consistent with morphine poisoning, providing investigators with a crucial breakthrough.
For years, unexplained deaths surrounding Toppan could potentially be dismissed as illness or natural causes.
The Davis case made that much harder to do.
Jane Toppan’s Arrest
The investigation into the Davis deaths eventually focused on Toppan.
Police arrested her in October 1901 in Amherst, New Hampshire.
By then, investigators were beginning to connect her to a much larger pattern of suspicious deaths.
What started as an investigation into several deaths threatened to become something far more disturbing.
Toppan was no longer simply a nurse connected to a suspicious family tragedy.
Investigators were beginning to suspect that she could be responsible for numerous deaths over the course of her nursing career.
Jane Toppan’s Confession
After her arrest, Toppan made an extraordinary confession.
She claimed that she had killed 31 people.
That confession is the basis for the figure most commonly associated with her today. Guinness World Records lists Jane Toppan as the most prolific female serial killer based on her confession to 31 murders.
However, the true number of her victims remains uncertain.
Toppan herself reportedly suggested that the number could have been considerably higher. Some historical accounts have repeated estimates of 100 or more potential victims, but those larger figures cannot be treated as confirmed murder totals.
The safest way to describe the case is:
Jane Toppan confessed to 31 murders, while the full number of people she may have killed remains unknown.
That distinction is important when discussing historical serial killers.
Why Did Jane Toppan Kill?
Toppan's stated motives were deeply disturbing.
She described experiencing an intense fascination with people who were near death and reportedly said that she received a sexual thrill from the process of killing.
Her own statements suggested that the act of bringing patients close to death and watching their condition change was part of the attraction.
Researchers have subsequently categorized Toppan among female serial killers who exploited caregiving roles to gain access to victims.
Her motives may not have been identical in every murder.
For example, the killing of her foster sister has sometimes been discussed as potentially involving personal resentment or jealousy, while many of her patient killings appeared connected to her fascination with death and control.
Jane Toppan’s Trial
Jane Toppan went to trial in 1902.
The case centered heavily on her mental state.
Doctors examined her and ultimately concluded that she was mentally ill and unable to be held fully responsible for her actions. The prosecution and defense ultimately accepted an insanity-based outcome.
Toppan was found not guilty by reason of insanity.
Instead of being released, she was committed to the Taunton State Hospital in Massachusetts.
She would remain institutionalized for the rest of her life.
What Happened to Jane Toppan?
Toppan spent decades confined to the psychiatric institution in Taunton.
Unlike many notorious killers whose stories ended with an execution or a prison sentence, Jane Toppan lived for decades after her crimes were exposed.
She died in 1938, having spent much of her adult life in institutional confinement.
By then, the woman once known as “Jolly Jane” had become one of the most infamous female serial killers in American history.
How Many People Did Jane Toppan Kill?
The short answer is:
Jane Toppan confessed to killing 31 people.
But that does not mean 31 murders were conclusively proven.
Toppan was formally prosecuted on 12 murder counts, while her confession expanded the potential number of victims considerably. Guinness recognizes the 31-person figure based on her confession.
Some historical sources have suggested that she may have killed many more people, potentially dozens beyond the 31 she named.
Those claims remain uncertain.
Because many of the suspected victims died before modern forensic practices existed, and because suspicious deaths could easily be attributed to natural illness, establishing the true extent of Toppan's crimes is nearly impossible today.
The possibility that her actual victim count was higher remains one of the most haunting aspects of the case.
Jane Toppan’s Legacy
Jane Toppan's story remains disturbing not simply because of the number of people she confessed to killing, but because of how she gained access to them.
She did not need to break into homes or stalk strangers.
People invited her inside.
They trusted her with sick relatives.
They gave her responsibility for patients who depended on her.
That trust became the weapon.
Toppan's case also illustrates the difficulty of investigating historical serial murders. Many of her suspected victims were elderly or seriously ill, making suspicious deaths easier to overlook. Without modern toxicology, medical records and investigative procedures, identifying a pattern could take years.
Her story is now frequently discussed alongside other so-called “angel of mercy” killers—caregivers who deliberately harm or murder people under their care.
But Jane Toppan's case remains particularly notorious because of the scale of her confession.
The Chilling Story of Jolly Jane
Jane Toppan's transformation from a seemingly cheerful nurse into one of America's most notorious serial killers remains difficult to comprehend.
She cultivated trust.
She entered homes as a caregiver.
She cared for people who were already vulnerable.
And according to her own confession, she used that position to kill again and again.
Whether Jane Toppan actually killed 31 people, dozens more, or even approached the much larger numbers sometimes suggested by historical accounts may never be known.
What is certain is that “Jolly Jane” was responsible for a series of murders that exposed a terrifying vulnerability in the medical and caregiving systems of her era.
Her case remains a chilling reminder that sometimes the most dangerous person in the room is the one everyone believes they can trust.
