Lies unravel and a web of jealousy and control tightens in this week’s Killer Britain with Dermot Murnaghan, airing Monday at 9 PM GMT on Crime & Investigation. The episode, titled Lacomba, revisits the case of Ben Lacomba, a man whose attempts to cover up the disappearance of Sarah expose a chilling level of calculation.
Murnaghan, revisiting a story he’s covered extensively, walks viewers through the investigation. Lacomba’s gamble—that no body would mean no conviction—begins to crumble as his carefully constructed narrative falls apart under scrutiny.
The series uses archival footage and key interviews to rebuild each case, giving voice to the victim’s families and the officers on the frontlines of the investigation. In this installment, the focus is on how Lacomba’s actions reveal a pattern of jealousy, possessiveness, and a disturbing lack of remorse.
True crime aficionados familiar with the case will find new insights here, while viewers unfamiliar with the story are in for a disturbingly close look at how quickly love can turn to hate.
Killer Britain with Dermot Murnaghan airs Monday at 9:00 PM GMT on Crime & Investigation.
