New Documentary Delves into the Crimes of Joanne Dennehy
A chilling new documentary titled Confessions of a Female Serial Killer has been released on Prime Video, shedding light on one of Britain's most notorious female serial killers, Joanne Dennehy. Many may not be familiar with her name, but her brutal crimes shocked the nation in 2013 when she stabbed three men to death over a ten-day period in March of that year.
A Life Sentence Without Parole
Dennehy is currently serving a whole life order behind bars, meaning she will never be released. She is only the third female serial killer in British history to receive such a sentence, alongside infamous figures like Myra Hindley and Rosemary West. The documentary provides a harrowing insight into her crimes, exploring how she continued her killing spree by seeking out two more victims, both of whom miraculously survived knife attacks.
From Middle-Class Upbringing to Deadly Path
Born in Hertfordshire in 1982, Dennehy came from a loving, middle-class family with high hopes for her future, including aspirations of becoming a lawyer. However, her life took a drastic turn in her teenage years after she fell in with a group of fairground workers. By age 13, she had turned to drink and drugs, eventually leaving home to embark on a relationship with John Treanor, who was five years her senior.
The couple faced spells of homelessness before settling into a flat, and Dennehy discovered she was pregnant with her first child at 17. Although she gave up substance abuse during the pregnancy, she quickly returned to her addiction after her daughter's birth. Treanor, her ex-partner, recounts in the documentary how he became the sole carer for their child, placing immense strain on their relationship.
Diagnosis and Descent into Violence
Dennehy's life spiraled further as she ended up in prison for a violent offence and was sectioned, leading to a diagnosis of antisocial psychopathic personality disorder by forensic psychologist Dr. Helen Hart. Dr. Hart explains in the documentary that individuals with this disorder often disregard society's rules, which may have contributed to Dennehy's actions.
After being released, Treanor gave their relationship another chance, and Dennehy soon fell pregnant with their second child. However, her addiction and erratic behavior eventually forced Treanor to take the children and leave. Dennehy then began an affair with her landlord, Kevin Lee, and acted as his enforcer for rent collection. Tragically, Lee would later become one of her victims, along with Lukasz Slaboszewski and John Chapman, all stabbed to death with a knife before their bodies were disposed of.
On the Run and Further Attacks
Following the murders in Peterborough, Cambridgeshire, Dennehy went on the run with her friend Gary Stretch, bragging about being a modern-day version of Bonnie and Clyde. They traveled through Norfolk, Worcester, and into Herefordshire, where Dennehy sought out new victims. In Hereford, she targeted two random dog walkers, Robin Bereza and John Rogers, attacking them with a knife and leaving them for dead. Both men survived the violent assaults.
Dennehy was eventually arrested in Hereford after two days on the run and sentenced in 2014. The documentary Confessions of a Female Serial Killer is now streaming on Prime Video, offering a detailed and unsettling look into her crimes and the psychological factors behind them.
