 The investigation included several appeals to the public for information, including a reconstruction on the BBC television programme "Crimewatch".During the investigation, over 900 police officers and support staff searched over 1500 locations for Jones's body, as within two months of her disappearance police working on the case were convinced that she was dead.On 17 August 2001 police re-arrested Campbell on suspicion of murder, after finding "significant evidence" which appeared to support their theory that Danielle Jones was now dead.
