Killer Steve Wright had been careful to try to dispose of all evidence linking him to his five victims, cleaning his car and his clothes. However, enough traces remained for forensic examiners to establish a link.
Each woman's body had a range of fibres on it which were also found on several of Wright's clothes and possessions (labelled "fibre link" in the table, right), although they did not come directly from those objects.
Some of the objects had also shed their own fibres directly onto the bodies (labelled "direct fibre transfer"). Even the bodies of Gemma Adams and Tania Nicol, who were found in water, had fibres on them.
An examination of Wright's car, gloves and fluorescent jacket found small amounts of blood and DNA which, the jury heard, matched that of three of the women.
Wright's DNA was also found on the bodies of Anneli Alderton, Paula Clennell and Annette Nicholls.
