Devotees of true crime programming have reported feeling physically unwell after watching a harrowing new episode of a documentary series that aired this week. The show, Channel 4's 'Catching a Killer', returned with a particularly disturbing instalment titled 'Buried Truths', which has been widely described by audiences as an intensely brutal watch.
Behind the Scenes of a Murder Investigation
The series, which first aired in 2017, grants viewers unprecedented access to the inner workings of a British police force as they investigate real-life murders and missing persons cases. Each episode follows a single investigation from the initial report to its conclusion, offering a raw look at the procedural race against time.
The latest case focuses on the disappearance of 45-year-old father Cumali Turhan in Essex. The investigation was launched after a concerned phone call revealed he had failed to turn up for work. The episode details how Essex Police uncovered a web of horrific events, leading to the discovery of Turhan's body at a landfill site.
Viewer Reaction: Shock and Nausea
The graphic nature of the case has provoked a visceral reaction from the show's audience. On social media platforms, particularly TikTok, viewers have expressed their distress, with many admitting the content made them feel physically ill.
One fan commented online, "OMG I only saw the end of the programme this is horrendous..." Another added, "Was that the one where they put him in the bin, not to mention cutting off his privates? Honestly it sickened me to the core, that poor man."
Further reactions highlighted the episode's impact: "I've just watched this!!!! OMG I feel physically sick! It's the worst thing I've ever seen," wrote one viewer. A fourth simply stated, "I don't usually squirm but that was brutal."
The Harrowing Details of the Case
According to reports, the case involves suspect Ceyhan Dinler, who is accused of a gruesome attack on Turhan in 2024. It is alleged the violence was motivated by a dispute over an affair. Dinler is accused of luring Turhan to a pub before stabbing him, mutilating him, and disposing of his body.
The police investigation was extensive. Essex Police reported that the search involved more than 1,650 officer shifts across 10 separate locations as they worked to solve the crime and locate the victim.
For those who missed the initial broadcast on January 8, 2026, the episode 'Catching a Killer: Buried Truths' is available to stream on demand via Channel 4's online platform. The series continues to be a flagship part of the channel's true crime offering, presenting unfiltered and often unsettling insights into major criminal investigations.
