From our reporter Rob Murphy in court:


Pros: Halliwell was minicab driver. He stopped her as she left night club. He took her to Savernake Forest where he stabbed her.


Halliwell had clocked off his shift. & turned off his cab tracking device. CCTV shows him cruising streets 'in circular movements...'


... Before abducting Sian. He makes 4 or 5 passes. CCTV shows him passing Sian, turn around and stop. Glare of headlamps distorts image
