Sister of murdered schoolgirl: 'We live in a loop of horror'

Kate Rimer, the sister of murdered schoolgirl Lindsay Rimer, has written an emotional Facebook post about the impact of her death. 13-year-old Lindsay disappeared from Hebden Bridge 20 years ago. Her body was found five months later weighed down in the Rochdale Canal. The killer has never been found. Kate Rimer says the family live in a "loop of horror" because they don't know who is responsible for Lindsay's death.

Today West Yorkshire Police is carrying out a 'tweeconstruction' - a reconstruction of the case and appeal using the social media platform, Twitter. You can follow it here. They have also released a new video retracing Lindsay's last known movements.
