2. Episode 2

In March 2020, 19-year-old Jaydon McFarlane was fatally stabbed in broad daylight on a residential street in Ashford, Kent, by a man wielding both a zombie knife and a kitchen knife. As detectives began a fast-moving investigation, they discovered how the victim and killer were former friends who had become members of rival gangs, involved in a dispute over counterfeit £20 notes used to buy cannabis, culminating in a terrifying chase through a shopping centre.

3. Episode 3

How forensic phone analysis led detectives to the murderer of Samantha Holden. In September 2022, Samantha Holden was found dead in her Farnborough flat in Hampshire. There were no obvious injuries, but her arm was pinned behind her back, her underwear was pulled down and her phone had vanished. The last text Samantha received was from an unknown number: 'I am 30 seconds from your door'. The message was sent by Adam Watson, a man with a history of sexual violence against women. But Watson was already on the run. Phone analysis showed he had fled to Brussels on the Eurostar. As his financial transactions offered fleeting clues to his movements, officers knew the trail would soon disappear as his bank account emptied. In a race against time, armed officers were deployed. While Samantha's post-mortem concluded that she had been strangled, would Watson claim that her death was the result of consensual sex gone wrong?
