The Murder Detectives Channel 4, 9pm
This documentary series follows a disturbing case from beginning to end. It starts with the 999 call made by 19-year-old Nicholas Robinson as he lay dying from multiple stab wounds in March, 2014. The newly engaged teen was studying at college and his only previous contact with the police had been to report a stolen bike, leaving officers wondering just who could have committed such a senseless crime. As Robinsons’ family struggle to take in the terrible news, the police seize on one potential lead – a black glove found at the scene.
