A cold case team is taking a fresh look at the suspected murder of schoolgirl Charlene Downes ahead of the 20th anniversary of her disappearance.
The 14-year-old vanished on November 1, 2003, when she failed to show up at her home in Blackpool.
Police over the years have tied to the case to a child sex ring in the town who they suspect had been grooming her with two men charged and tried, although tragically nobody has ever been convicted.
