Serial killers and the crimes that remained in the shadows for years

At 22:00, the masks come off. A dark July with serial killers

Serial killers do not disappear with time. Their crimes continue to fascinate investigators, horrify the public, and leave behind questions that often remain unanswered for years. This July, Viasat True Crime invites viewers to a particularly chilling line-up dedicated to people who led double lives, hid their darkest obsessions, and committed acts that defy human understanding.

Every evening at 22:00, viewers will be confronted with stories that shocked entire nations. These are tales of serial murder, sexual obsession, cannibalism, secret lives, and investigations that remained unsolved for decades.

Murderer Behind the Mask -- the July premiere exposing a killer's double life

Premiere: Monday 6 July at 22:00 CET and Tuesday 7 July at 22:00 CET

Encore: Sunday 12 July from 21:00 CET

Joining Viasat True Crime's infamous gallery of serial killers is Graham Dwyer, a man long regarded as the picture of success. A respected architect, husband, and father of two, he appeared to have it all. Few suspected that behind the façade of a perfect life lurked a man consumed by dangerous obsessions.

Murderer Behind the Mask follows an investigation that began with the chance discovery of the remains of a missing woman. The evidence was limited, yet Irish detectives managed to build one of the most groundbreaking murder cases in the country's history.

The case became a landmark investigation thanks to the unprecedented use of mobile phone data to reconstruct the movements of a suspect. The result is a story that demonstrates a disturbing truth: sometimes the most dangerous people look exactly like those we trust every day.

The Cannibal Next Door -- when the victim agrees to die

Broadcast: Wednesday 8 July at 22:00 CET

Few criminal cases in modern history have provoked as much disbelief as that of Armin Meiwes.

For years he fantasised about eating another human being. Eventually, he posted an advertisement online. To his astonishment, someone answered.

The Cannibal Next Door tells the shocking story of a meeting between two men that ended in one of the most disturbing crimes of the 21st century. The documentary not only examines what happened but also explores how both perpetrator and victim willingly found themselves on the same path.

To this day, the case continues to raise difficult legal, ethical, and psychological questions.

Monster in the Morgue -- the killer hunted for 33 years

Broadcast: Thursday 9 July and Friday 10 July at 22:00 CET

Some investigations last months. Others last years. This one lasted more than three decades.

Monster in the Morgue revisits the murders of Wendy Knell and Caroline Pierce, two women brutally killed in Kent, England. For years, police believed the crimes were linked, but lacked the evidence needed to identify the perpetrator.

It was not until 2020 that detectives finally arrested David Fuller.

But that was only the beginning.

As the investigation expanded, authorities uncovered evidence that Fuller had spent years abusing his position within hospital mortuaries to commit further crimes. The scale of his offending was so shocking that the case became one of the most disturbing criminal scandals in modern British history.

Serial killers hiding behind a mask of normality

Although the stories featured this July are very different, they share one unsettling characteristic: the perpetrators remained unnoticed for years.

Graham Dwyer was a respected professional. Armin Meiwes lived a seemingly quiet life in a small German town. David Fuller spent decades working in healthcare without attracting serious suspicion.

That is precisely why these cases continue to resonate so strongly. They remind us that real evil rarely looks the way it does in films.

Sometimes it wears a suit. Sometimes it works in a hospital. Sometimes it lives next door.

Serial killers without their masks

In July, 22:00 marks the moment darkness falls on Viasat True Crime.

Murderer Behind the Mask, The Cannibal Next Door, and Monster in the Morgue are stories of obsession, violence, and investigations that exposed some of the most disturbing aspects of human nature.

These are stories that show how the most dangerous criminals often remain invisible for years.

Tune in to Viasat True Crime every night at 22:00 and remove the mask from serial killers yourself.
