Patty Cannon: Kidnapper, Slave Trader and Serial Murderer
Martha "Patty" Cannon was one of the most notorious criminals associated with the early nineteenth-century traffic in kidnapped free Black Americans. Operating along the Delaware-Maryland border, Cannon and the group commonly called the Cannon-Johnson Gang abducted free Black men, women and children, held them captive, and transported them south to be sold into slavery. Cannon was also accused of murdering people who threatened the operation, could not easily be sold, or possessed money the gang wanted to steal. Although later stories dramatically expanded the number of murders attributed to her, surviving historical records establish that Cannon was formally indicted for four murders in 1829 and that multiple sets of human remains were uncovered on property associated with her criminal enterprise.
Patty Cannon and the Cannon-Johnson Gang
Cannon lived in the region around what is now Reliance, near the Maryland-Delaware state line. Her home and properties connected to her family were situated in an area where the boundaries of Sussex County, Delaware, and Caroline and Dorchester counties in Maryland provided criminals with opportunities to move from one jurisdiction to another. Stories that Cannon could simply step across a state line whenever authorities approached became part of her legend, although some of the more colorful versions of those stories were written long after her death.
Cannon's most important criminal associate was her son-in-law, Joseph "Joe" Johnson. Johnson operated a tavern and worked as a slave trader. His brother, Ebenezer F. Johnson, was also implicated in violent activities connected with the gang. Other individuals associated with the network at various times included Henry Carr, John Purnell and Cyrus James.
The gang participated in what later became known as the "Reverse Underground Railroad." Rather than helping enslaved people escape to freedom, criminal kidnapping networks abducted free Black people from northern and border states and forced them into slavery. Victims could be seized from roads, farms, homes or cities, transported far away from their families, and sold to buyers who had little incentive to investigate whether the person being sold was legally free.
Kidnapping Free Black Americans
Cannon's organization was accused of kidnapping large numbers of free Black Americans from Maryland, Delaware, Pennsylvania and surrounding areas. Captives were taken to secluded properties controlled by Cannon and Johnson, where they could be concealed until arrangements were made to transport them south. Accounts given by people who survived the operation described prisoners being restrained, threatened and beaten when they protested that they were free.
Some captives were moved through the Nanticoke River and Chesapeake Bay region before being transported to southern slave markets. Others were taken overland. Alabama, Mississippi and Georgia were among the destinations connected with members of the trafficking network. Once a victim had been taken hundreds of miles from home and sold, proving free status could become extraordinarily difficult.
One documented kidnapping survivor was Lydia Smith, a 25-year-old free Black woman. Smith stated that she was kidnapped in 1825 and held at Cannon's house before being transferred to Johnson's tavern. She remained captive for months before being transported south with a larger group. Testimony from Smith and other recovered kidnapping victims eventually provided authorities with evidence about the gang's methods.
Violence Within the Criminal Operation
Murder appears to have served several purposes within the Cannon-Johnson operation. Some victims were allegedly killed because the gang feared they might expose the kidnappers. Other murders appear to have been motivated by robbery. Historical accounts also describe children being killed when Cannon or her associates decided that transporting or concealing them presented a problem.
The most important surviving testimony came from Cyrus James, a Black man who had been raised in Cannon's household from childhood and became involved in the gang's activities. After he was apprehended in 1829, James described murders he said he had witnessed and directed authorities to places where bodies had been buried.
James told investigators that Cannon had personally killed at least one child by striking the child in the head with a piece of wood. When investigators recovered the child's remains, damage to the skull was reportedly consistent with the account James had provided. He also described the killing of another young child whose mother was enslaved by Cannon.
The Murdered Slave Trader
Another murder described in contemporary reports involved a slave trader from Georgia. His identity was uncertain even when the case became public in 1829. Newspapers reported that he was remembered as a man named Bell or Miller, or possibly as someone associated with both names.
According to the account provided by Cyrus James, Joseph Johnson, Ebenezer Johnson and Patty Cannon participated in shooting the man while he was eating at Cannon's house. James said he then saw the group place the body inside a chest and bury it. The trader was reportedly carrying a large amount of money intended for purchasing enslaved people, giving the gang a financial motive for killing him.
Years later, a tenant plowing ground associated with Cannon and Johnson uncovered a grave containing a blue-painted chest and the bones of an adult man. Residents immediately connected the discovery with the slave trader who had disappeared years earlier. Because the man's identity and precise date of death were never conclusively established, he should be regarded as a suspected victim rather than identified with certainty as one of the four people named by description in Cannon's murder indictments.
Discovery of the Bodies in 1829
The investigation that finally ended Cannon's operation began in the spring of 1829. Human remains were uncovered on property in Northwest Fork Hundred in Sussex County, Delaware, close to the Maryland border. After the discovery of the first grave, authorities and local residents began searching other locations.
Cyrus James was apprehended in early April 1829. During questioning, he told authorities that many people had been killed and said he could identify burial locations. Investigators accompanied him to Cannon-associated property, where additional human remains were discovered.
One burial site was in a garden. Another search uncovered oak boxes containing human bones. Some of the remains belonged to children. The discoveries transformed longstanding accusations surrounding Cannon and Johnson into a murder investigation supported by physical evidence.
Documented Murder Victims
The names of the four people whose deaths formed the basis of Cannon's 1829 murder charges do not appear to have survived in the available indictment summaries. The dates below are the murder dates alleged in the indictments and are therefore considerably better documented than dates attached to victims in later legends about Cannon.
- Unidentified adult Black man - October 1, 1820 - Sussex County, Delaware area. Cannon was indicted for the murder of an adult male on this date. Human remains belonging to an adult were among those recovered from property connected with the Cannon-Johnson operation in Northwest Fork Hundred. The surviving summaries do not provide the victim's name, and he should not automatically be identified with the Georgia slave trader sometimes called Bell or Miller.
- Unidentified infant girl - April 26, 1822 - Sussex County, Delaware area. One murder indictment concerned an infant female killed on April 26, 1822. Testimony associated with the investigation described Cannon killing a young child whose mother was enslaved by her. The child's remains were reportedly found buried in a garden, although the surviving record does not preserve a reliable name for the infant.
- Unidentified male child - April 26, 1822 - Sussex County, Delaware area. A second child was alleged to have been murdered on the same date. Historical accounts of the excavation describe children's remains recovered from Cannon-associated property. Because records from the investigation provide descriptions rather than names, the child's identity remains unknown.
- Unidentified Black boy - June 1, 1824 - Sussex County, Delaware area. The fourth documented murder charge involved a Black boy killed on June 1, 1824. Cyrus James described witnessing Cannon fatally assault a child with a piece of wood, and investigators reportedly discovered damage to recovered skull remains that supported his description. No verified name for the boy has been preserved in the commonly available court summaries.
Other Suspected Victims
The four indictment victims do not necessarily represent the complete number of people killed by Cannon and her associates. Contemporary reporting following the discovery of the graves claimed that additional people had disappeared after coming into contact with the gang. Cyrus James himself reportedly told authorities that many other people had been killed.
The unidentified Georgia slave trader known in contemporary reports as "Bell or Miller" is among the strongest additional suspected victims. His disappearance had occurred roughly a decade before the bodies were discovered. His horse reportedly remained at Cannon's property after he disappeared, and Cannon allegedly claimed that the man had departed for the South. When an adult body was eventually found inside a buried chest, local residents believed it belonged to the missing trader. James subsequently described a killing that closely matched the circumstances surrounding that disappearance.
Later books and sensational accounts attributed much larger numbers of murders to Cannon, sometimes claiming that she confessed to eleven, twenty or more killings. Those numbers should be treated cautiously. Nineteenth-century newspaper stories, fictionalized narratives and later folklore frequently became mixed together. The four murder charges filed in 1829 and the bodies uncovered during the investigation provide the most defensible minimum number of documented murder victims connected directly to Cannon.
Arrest and Murder Charges
After the graves were uncovered, Cannon was arrested and jailed in Georgetown, Delaware. Cyrus James and another man identified as Butler were also taken into custody. Joseph Johnson, however, was not immediately captured. Reports indicated that he may have fled south, possibly to Alabama.
On April 13, 1829, legal proceedings in Sussex County produced murder indictments connected with the remains and testimony. Cannon faced charges covering four killings. The discoveries attracted widespread attention, and newspapers throughout the United States reprinted descriptions of the graves, the recovered bones and James's statements about the murders.
Cannon never stood through a completed murder trial. While confined in the Sussex County jail at Georgetown, she died on May 11, 1829. She was believed to have been between approximately 60 and 70 years old, although even her birth year remains uncertain.
Patty Cannon's Death
The cause of Cannon's death has never been established with certainty. The best-known version of the story says that she obtained poison and deliberately killed herself while awaiting trial. Other accounts leave open the possibility of natural causes or another unexplained death. Because the surviving contemporary evidence does not conclusively settle the matter, describing her death simply as a proven suicide goes beyond what can be firmly established.
She was initially buried near the Georgetown jail. Stories surrounding her remains, particularly claims concerning her skull, later became another part of the extensive folklore that developed around the Cannon case.
Historical Significance
Patty Cannon's crimes are particularly significant because they reveal the organized kidnapping networks that preyed upon free Black Americans during the era of slavery. Murder was only one part of the devastation caused by the Cannon-Johnson Gang. People who survived being kidnapped could lose their names, freedom, property and families after being transported to distant states and illegally sold.
For generations, Cannon was frequently portrayed through sensational stories emphasizing her physical strength, cruelty and supposed enormous murder count. Modern historical examination requires separating those legends from the evidence. There is strong documentation that Cannon participated in a large-scale kidnapping and human-trafficking organization, that human remains were discovered on property associated with the operation, that an eyewitness implicated her in killings, and that she was formally accused of four murders before her death.
Although the identities of the four indictment victims have largely been lost, their recorded murder dates - October 1, 1820; April 26, 1822; April 26, 1822; and June 1, 1824 - remain part of the surviving legal history of the case. The namelessness of those victims reflects one of the lasting tragedies surrounding the Cannon-Johnson Gang: many of the Black men, women and children it victimized entered the historical record only through descriptions written by the people who kidnapped, imprisoned, sold or investigated them.
Legacy
Patty Cannon died before a jury could determine her guilt on the murder indictments, but the physical evidence discovered in 1829 and the testimony concerning the Cannon-Johnson Gang established a grim historical record. Her organization exploited slavery for profit while deliberately targeting people whose freedom could be stolen through violence and deception.
Today Cannon is remembered not merely as an early American serial murderer, but as a central figure in a broader system of kidnapping and illegal human trafficking. The most reliable record supports at least four documented murder charges, additional suspected murders, and a much larger population of kidnapping victims whose lives were permanently altered by the gang. Separating verified evidence from later folklore provides the clearest picture of both Cannon's crimes and the people who suffered because of them.
