This experience did little to reform him, and he continued to engage in criminal activities throughout his life.

    The Crimes of Fritz Haarmann

    The crimes of Fritz Haarmann are among the most gruesome in history. Between 1918 and 1924, he murdered at least 24 young men, although some estimates suggest the number could be higher. His victims were primarily homeless teenagers and young men who lived on the fringes of society.

    The Investigation Process

    The investigation into Fritz Haarmann's crimes was fraught with challenges. The discovery of human remains in the Weser River in 1924 initially baffled authorities, as the bodies were dismembered and unidentifiable. It wasn't until a breakthrough in forensic science that the police were able to connect the remains to Haarmann.

    Forensic Breakthrough

    One of the key moments in the investigation came when forensic experts discovered teeth marks on the bones. These marks matched Haarmann's dentition, providing irrefutable evidence of his involvement in the murders. This forensic breakthrough not only led to Haarmann's arrest but also set a precedent for future investigations.

    Arrest and Trial

    Fritz Haarmann was arrested on November 22, 1924, after police gathered sufficient evidence against him. During his trial, Haarmann confessed to 24 murders, although he claimed that his accomplice, Hans Grans, was responsible for disposing of the bodies.

    The trial, which took place in 1925, captured the attention of the nation. Haarmann's demeanor during the proceedings was calm and detached, further unsettling the public. On April 15, 1925, Fritz Haarmann was executed by guillotine, bringing an end to one of Germany's most infamous criminal cases.
