West Yorkshire Police launches 'tweeconstruction' on Twitter to track down schoolgirl killer
Police have taken to Twitter to help track down the murderer of a schoolgirl in a case which has frustrated detectives for over two decades.

Detective superintendent Simon Atkinson
On Saturday (8 November), West Yorkshire Police launched what it called a “Tweeconstruction” - short for Twitter-reconstruction - of murdered 13-year-old Lindsay Jo Rimer's final hours.
The campaign took social media users through Rimer's last known whereabouts before her disappearance, in a bid to jog their memories.
The reconstruction featured a YouTube video from detective superintendent Simon Atkinson who stated that he was “desperate to close the case and bring closure to Lindsay’s grieving family”.

Those with information were urged to contact West Yorkshire Police or Crimestoppers in a bid to track down the person responsible.
On those behind the disappearance, detective superintendent Simon Atkinson, said: “He or she remains at large and that’s 20 years where they’ve been able to enjoy their liberty as Lindsay’s family grieve for her. Lindsay was only a young girl with her whole life ahead of her. Someone, somewhere knows what’s happened to her.”
He added: “We have already had a number of calls with information and will be following those up to see if they help the appeal at all.”
