Christopher Halliwell. The name evokes a chilling reminder of the darkness that can lurk beneath the surface of everyday life. A seemingly ordinary taxi driver from Swindon, Halliwell's crimes shattered lives and left a trail of unanswered questions. This is the story of Sian O'Callaghan and Becky Godden-Edwards, victims of a predator hiding in plain sight, and the lingering suspicion that he may have claimed more lives.
In March 2011, 22-year-old Sian O'Callaghan vanished after a night out in Swindon. CCTV footage captured her leaving a nightclub and walking towards her flat. A car, later linked to Halliwell, was also visible in the footage. The police investigation led them to Halliwell, who was observed disposing of items from his car and burning others.
Halliwell's arrest brought a shocking confession. He led police to Sian's body, found in a remote location. She had died from a head injury. In a disturbing twist, Halliwell then led them to a second body, identified as Becky Godden-Edwards, who had been missing since 2007. The investigation was complicated by the lead investigator's breach of police protocol during the confessions, a factor that would later impact the case.
Halliwell was convicted of Sian's murder and sentenced to life imprisonment. The case of Becky's murder was initially dropped due to the technicality surrounding the confession. However, Becky's mother's unwavering determination led to new evidence, and Halliwell was eventually convicted of her murder as well, receiving a whole life order.
The case took an even darker turn with the discovery of buried women's clothing, including items belonging to Sian and Becky, alongside other unidentified garments. This discovery fueled the suspicion that Halliwell was responsible for other unsolved disappearances. Reports surfaced of sex workers who had encountered Halliwell, describing his increasingly aggressive behavior. A former colleague even recalled Halliwell asking him how many people he would have to kill to be considered a serial killer.
Further connections emerged, linking Halliwell to other missing women. Sian disappeared on March 19th, a date that coincided with a personal event in Halliwell's past. This same date was also linked to the disappearance of Linda Razzell in 2002, a woman with whom Halliwell had had an affair, and whose husband was convicted of her murder despite maintaining his innocence. In 2009, on March 19th, Claudia Lawrence disappeared in York, a city frequented by Halliwell. He was said to match witness descriptions of a man seen near Lawrence. Sally Ann John, a sex worker from Swindon, disappeared in 1995 after reports that Halliwell had become obsessed with her. While some arrests were made in connection with her case, it remains unsolved.
While Halliwell has not confessed to other killings, the evidence and coincidences suggest a far wider scope to his crimes. The discovery of the clothing, the reports of his behaviour, and the recurring link to disappearances on March 19th all point to the horrifying possibility that Christopher Halliwell is responsible for more unsolved murders.
