On 3 August 2012, as London was gripped by the Olympics, Tia Sharp, a 12-year old schoolgirl, was reported missing from her grandmother's home in New Addington, south London. A call made by her mother, Natalie, alerted police to Tia's disappearance and so began a massive search operation to find the missing girl. Police were seconded from the Olympic village to make house-tohouse enquiries, while locals searched the nearby area.

A Twitter campaign began, sparking a nationwide appeal to find Tia. It was reported that Tia had disappeared after being dropped off at a train station to go shopping, but in the days that followed a different story emerged.

Only seven days after Tia was reported missing, the terrible news came that the family hoped they would never have to hear; Tia's body, wrapped in bin bags, had been found in her grandmother's attic. The truth that unfolded over the course of the day horrified the public; not only had the police searched the house on three separate occasions before discovering Tia's body, late the following evening, Stuart Hazell – the man who Tia trusted, the man who appealed for her return – was charged with her murder.
