The 13-year-old schoolgirl was groomed online over a period of 13 days in 2015 by Luke Harlow, before she agreed to meet him.
Two days later, Kayleigh was raped and murdered by Harlow’s next door neighbour, Stephen Beadman.
Following a trial at Nottingham crown court both men were jailed.
Harlow was sentenced to prison for 12 years, and Beadman to life with a recommendation that he serve a minimum of 35 years behind bars.
The documentary features interviews with Detective Inspector Simon Shuttleworth, who was the deputy investigating officer in the case. It also features interviews with Kayleigh’s mother Stephanie, and with Miranda Moore QC who successfully prosecuted Harlow and Beadman at court.
As well as focusing on the investigation, the documentary will also highlight how Leicestershire Police made a short documentary titled ‘Kayleigh’s Love Story’ (watch below).
Kayleigh’s Love Story has since been viewed by 30 million people online.
