A taxi driver has pleaded guilty to the murder of Sian O'Callaghan, who'd gone missing after a night out in Swindon last year. Christopher Halliwell admitted sexually assaulting her and stabbing her before dumping her body.
Today Bristol Crown Court heard Halliwell had been cruising around Swindon that night deliberately looking for a victim. However it's emerged that police were not able to proceed with another murder charge because of a legal mistake.
Our Wiltshire reporter Robert Murphy has been following the case and reports from Bristol Crown Court.
Chris Halliwell's daughter has appeared on ITV's Daybreak asking her father to give "justice" to the family of the second woman he killed.
Swindon taxi driver Chris Halliwell has been jailed for the murder of Sian O'Callaghan but is he guilty of the murder of other women?
It was a fluke, in a way, that Halliwell was ever caught. But it also needed some good detective work.
