By 2025, his name remains significant in discussions of serial killers, unsolved murders, and police investigative failures.
Who Is Christopher Halliwell?
Christopher Halliwell is a convicted murderer born in 1964 in Swindon, Wiltshire, England. Before his crimes were exposed, Halliwell was employed as a taxi driver, living a relatively unremarkable life. Outwardly, he appeared to be an ordinary member of society, but behind this facade lurked a dangerous obsession with women, control, and ultimately murder.
Halliwell’s arrest in 2011 and subsequent convictions revealed that he was not a one-time offender but a calculated killer with potential links to several other unsolved cases. He is currently serving a whole life sentence, meaning he will never be released from prison.
The Murders That Shook the UK
The Murder of Sian O’Callaghan
Sian O’Callaghan, a 22-year-old office worker from Swindon, disappeared in March 2011 after leaving a nightclub. Her disappearance triggered a high-profile missing persons investigation.
Halliwell, working as a taxi driver, was identified through CCTV footage and phone records as the last person to see Sian alive. After being confronted by police, he eventually led officers to her body, which he had dumped in a remote woodland area.
The shocking nature of Sian’s abduction and murder, combined with Halliwell’s cold demeanor, captured national attention. It also raised concerns about women’s safety when using taxis or traveling alone late at night.
The Murder of Becky Godden-Edwards
During police questioning in 2011, Halliwell also confessed to killing another woman, later identified as Becky Godden-Edwards, a 20-year-old sex worker who had gone missing in 2003.
Her body was found in a shallow grave after Halliwell guided police to the location. However, complications during the investigation meant that his confession was initially deemed inadmissible due to procedural issues, delaying justice for Becky’s family until 2016, when he was finally convicted of her murder.
These two murders cemented Halliwell’s reputation as one of the most dangerous criminals in modern British history.
Investigations and Legal Challenges
The investigation into Christopher Halliwell was controversial from the start. While his eventual convictions were seen as victories for justice, there were missteps along the way that attracted criticism.
One of the most debated moments was Detective Superintendent Steve Fulcher’s decision to bypass police procedure in order to extract a confession from Halliwell. Though Fulcher’s approach led to the discovery of Becky’s body, it also complicated the legal process and ultimately ended his policing career.
This sparked a nationwide discussion on the balance between strict adherence to rules and the moral responsibility to recover victims and bring closure to families.
Could There Be More Victims?
One of the darkest aspects of the Halliwell case is the possibility that he murdered more women than the two confirmed victims.
Police have investigated multiple unsolved cases that may be connected to Halliwell, including disappearances dating back to the 1980s. Items such as women’s clothing, shoes, and handbags were found in a trophy-like collection hidden by Halliwell, leading investigators to suspect that these belonged to other, unidentified victims.
As of 2025, no additional murders have been officially linked to him in court, but families of missing women and advocacy groups continue to push for deeper investigations.
Psychological Profile of Christopher Halliwell
Criminal psychologists studying Halliwell describe him as a manipulative and controlling individual. His behavior shows several traits consistent with organized serial killers, including:
- Ability to mask his criminal behavior by maintaining an ordinary life.
- Pre-meditated approach to selecting and disposing of victims.
- Collection of personal items from victims, suggesting trophy-taking behavior.
Experts suggest that Halliwell may have been active for decades before being caught, exploiting his position as a taxi driver to target vulnerable women.
