A guttural scream could be heard from a neighbouring compartment on a London train to Victoria. It had just pulled away from Brixton, and as the train sped along the tracks, an 18-year-old french au pair remained glued to her seat in terror. She was not sure what to do. She could tell that the noises were screams of fear from a female in the next compartment, but she was too frightened to raise the alarm. By the time the train pulled into Victoria, it was too late. Someone dashed through the carriage door and out of the station before anyone realised what had occurred. Over three decades later, it is still unclear what exactly happened on the 2:16 train…

Daniel Hathaway, more commonly known as Danny, left his home at a travellers site off Gretton Brook Road in Corby, Northamptonshire.

It is estimated that around 170,000 people are reported missing each year in the United Kingdom. Of that number, approximately 98,000 are adults, and more than 70,000 are children. The average age for a first-time runaway is 13, and one out of four missing children will have been the victims of physical or sexual abuse. Children living in residential care are three times more likely to run away than peers living with their families. Those in care are also more vulnerable to abduction and grooming. While most of these missing people do eventually return home, a small percentage turn up dead, and an even smaller number still remain missing…
