When he was arrested and interviewed by police in 2010, Griffiths claimed to officers to have killed a total of five sex workers in Bradford, suggesting there were two additional victims unaccounted for. Griffiths knew Hall and she was known to regularly visit his flat. His former partner at the time revealed that Griffiths had excitedly taken her to the place where her body had been found, and also said that the car park was next to his doctor's surgery and pharmacy. The murder was one of several
cold cases to be re-opened after Taylor's conviction and he was questioned about it, in part because evidence showed Hall's body had been stored for a period after her death, which was a known hallmark of Taylor. In 2013,
criminologist David Wilson released a documentary on Griffiths as part of his
Killers Behind Bars: The Untold Story series, in which he examined unsolved murders that could be linked to Griffiths. The former lead detective on the case revealed in 2018 that two DNA profiles had previously been extracted from Hall's clothing, but the profiles were of too poor quality at the time to determine what the full profile of the unidentified individual was. Following this, in 2019, police announced the arrest of a 37-year-old woman (who would have been the same age as Hall at the time, 19). The woman was released under investigation. == See also ==
