Air date: Jul 23, 2018

In Acomb, York, police received a concerned 999 call reporting the erratic behaviour of Mark Webb threatening to self harm. When a lone police officer arrived to check the disturbance, Mark Webb was found dead with his throat cut. But a neighbour's eyewitness account would throw the investigation into turmoil and lead to the arrest of four of Acomb's residents.
