A mysterious criminal case unfolds: dark and suspenseful details, the perpetrator's profile makes us suspicious and the investigators doubt the truth of some of the witness statements. Slightly oppressive and subliminally threatening.

The facts and evidence are on the table, but the actual motive and the course of events remain a mystery. Despite an attempt at explanation, doubt and uncertainty remain, and a well-considered doubt spreads.

The culprit is a member of the victim's immediate family. Dark and frightening, with a disturbing moment of shock where a person's truth and true intentions are revealed.

The hunt for the killer begins. Suspenseful drama mixes with heroic technical determination. Perfect for prosecutions and arrests after long investigations.

A plea for a murderer in court. The jury is misled with twisted facts and probabilities. Doubts and mistrust grow, but how far can a system bend when it comes to human beings?

Not every crime is solved. Many cases remain unsolved, sins unpunished and relatives left without the truth. The Cold Case Archive tells their stories.

A teenager disappears without a trace. Panic and shock mix with the sheer fear of the parents. But the investigators are helpless, because they don't know where to start.

The motive: love. At least that's what the killer thinks. In reality, hurt feelings and an egocentric view of the world are the real driving force behind the shocking act. Dramatic and mysterious.

Can a perpetrator be a victim? Has the victim really been harmed, or is it all a big lie in which the real victim has been deliberately turned into the perpetrator? Frightening and full of doubt.

A disturbing pattern emerges: driven by greed and cold-blooded calculation. And yet investigators find it difficult to catch the culprit, even though the angry victims have already provided them with enough evidence.

Profiling a killer is a frightening and threatening practice, because delving into the psyche of a monster always leaves traces on one's own soul. Panic and shock in the face of dramatic truth.

The eerie moment when the victim becomes the perpetrator. Sometimes this role reversal happens suddenly in the heat of the moment, sometimes it is a development that takes years, full of dark thoughts and desperate cries for help.

The victim has survived, but for a long time, if not forever, he or she remains a broken person. Deep wounds in the heart and soul that leave relatives feeling helpless and angry because for the investigators the case is largely closed.

A brief moment of inattention and the trap snaps shut. The small dose of nerve gas is enough to cause irreversible damage: the death of an unwelcome adversary and leader of a dangerous political counter-movement.

One panic attack follows the other, the nights are plagued by anxiety attacks, because what has happened cannot be forgotten.
