24 Hours in Police Custody

Detectives from the Major Crime Unit have a suspect in custody but they're shocked when what their investigation reveals is even more devastating and important than their worst fears. Forensic analysis of his life online demonstrates that he craved notoriety by becoming the most deadly mass school shooter in history, and that he had based his plans on what he had found online about other school shooters.

The UK's biggest and most successful true crime documentary series returns with a two-part special which follows the investigation into a dispute over the custody of a child which ends in the fatal shooting of a father and son. On the evening of 29 March 2023, police receive a 999 call to an address in the quiet Cambridgeshire village of Bluntisham after a shotgun has been heard. A man has been fatally shot. The perpetrator has fled the scene. The murder has all the characteristics of an execution. Within minutes, a new emergency call is received for another shooting in another village just a 10-minute drive away. A second victim is discovered fatally wounded. The new victim is the father of the first man found dead. Detectives from the Major Crime Unit establish that the motive for the double murder could lie in a dispute over who should have custody of the child of the first victim - and they identify two potential suspects. Cameras follow the twists and turns of a double manhunt as police discover that their first suspect is holed up in a nearby hotel with the mother of the child while their second suspect - the grandfather of the child - is heading to the west in a camper van and still armed. In time, with both suspects now in custody, the interviews begin. What caused the apparent escalation of a family dispute into a brutal double execution? This is real real-life documentary where the drama is more compelling and disturbing than the best crime fiction. 

A 32-year-old man and his 57-year-old father have been murdered, each man shot dead with a shotgun at point blank range at their homes in villages 10 miles apart in a quiet part of Cambridgeshire. After a county-wide manhunt, police have three suspects in custody. At the centre of the tragic crime is a dispute over the custody of a child. Detectives believe that they have compelling evidence that the child's grandfather was directly responsible. But did he act alone? Can text messages and CCTV prove a wider conspiracy to murder? Cameras follow as the double murder investigation reaches its final dramatic conclusion.
