Joanna Dennehy is a British serial killer who murdered three men in Peterborough, Cambridgeshire, England, in 2013. She is one of only four women in the United Kingdom to have been sentenced to a whole-life order, meaning she will never be released from prison.
Early life and criminal history
Joanna Dennehy was born in St Albans, Hertfordshire, England, on August 4, 1982. She had a troubled childhood, and she was involved in petty crime from an early age. She was first convicted of an offense at the age of 13 for stealing a bicycle. She was later convicted of burglary, theft, and assault.
The Peterborough ditch murders
In March 2013, Dennehy embarked on a killing spree that lasted for ten days. Her first victim was Lukasz Slaboszewski, a 31-year-old Polish national who was living in Peterborough. Dennehy met Slaboszewski through her drug dealer, and she persuaded him to go to her flat in the city center. Once he was there, she stabbed him to death and dismembered his body.
Dennehy’s next victim was her landlord, Kevin Lee, a 48-year-old man who lived near her flat. She lured Lee to her flat under the pretense that she needed help with some work. Once he was there, she stabbed him to death and dismembered his body as well.
Dennehy’s third victim was John Chapman, a 56-year-old man who was Dennehy’s housemate. She stabbed him to death in his flat and then dumped his body in a ditch near Huntingdon, Cambridgeshire.
Arrest and trial
Dennehy was arrested on March 23, 2013, after she was seen driving a van that was registered to one of her victims. She was charged with three counts of murder, one count of attempted murder, and one count of preventing the lawful burial of a body.
Dennehy pleaded guilty to all of the charges against her at her trial in January 2014. She was sentenced to life imprisonment with a whole-life order.
Current status
Dennehy is currently serving her sentence at HMP Low Newton, a maximum-security prison for women in Durham, England. She is considered to be a high-risk prisoner and is under constant surveillance.

Joanna Dennehy’s crimes were shocking and horrific, and they sent shockwaves through the community of Peterborough. She is considered to be one of the most dangerous and sadistic serial killers in British history.
Early Encounters with the Legal System
Dennehy’s criminal activities soon caught the attention of the authorities. She was first convicted of an offense at the age of 13 for stealing a bicycle. Over the next few years, she accumulated a string of convictions for burglary, theft, and assault.
Escalating Violence and Mental Health Concerns
As Dennehy entered her early twenties, her behavior became increasingly violent and unpredictable. She was involved in several serious assaults and was suspected of carrying knives. Her mental health also deteriorated, leading to hospitalizations for self-harm and psychotic episodes.
Psychological Profile and Motivations
Psychological assessments of Dennehy revealed a complex profile marked by personality disorders, including antisocial personality disorder and sadistic traits. She exhibited a lack of empathy, remorse, or guilt for her actions.
Investigators believe that Dennehy’s motives for the murders were a combination of sadistic pleasure, a desire for power and control, and a need to prove her dominance over men. She had expressed admiration for serial killers and fantasies of committing violence.
