Detectives probing the mysterious murder of teenager Kieran Williams say investigations are continuing after a new witness hotline was launched.
It has now been more than a year since the 18-year-old's body was found in a makeshift grave, in Sunderland, six weeks after he went missing from home.
Louis Hackett, who had been friends with Kieran was convicted of manslaughter but cleared of murder, after a trial at Newcastle Crown Court.
