The Serpent 

Charles Sobhraj, a killer of mixed Vietnamese and Indian descent, was convicted for committing heinous murders across several countries including India, Nepal, Thailand, Turkey, and Iran. He had a delusional belief that he was a superior being, likening himself to a superman, and considered his actions as a means of purifying the world. Travelers who ventured along what he referred to as the 'Hippie Trail' in Asia witnessed Sobhraj using pills and powders to make his victims ill before ultimately stabbing or burning their bodies. In a similar incident, he attempted to poison 60 French tourists staying at an Indian hotel, but they were fortunate enough to only suffer from diarrhea, leading to his arrest. Sobhraj, also known as 'The Serpent', made several successful attempts to escape from prison, but he is currently securely held behind bars in Nepal. However, it is likely that he will soon make another attempt to flee.

The S-Bahn Murderer

Paul Orgozow was a Nazi and a notorious murderer who brutally killed women by stabbing and beating them to death. He would then dispose of their bodies by throwing them off the train that ran along the S-Bahn railway line.

Each time, he would employ different weapons to carry out his gruesome acts, resulting in the deaths of approximately 52 people throughout his lifetime. Upon his arrest, he feigned insanity, attributing the murders to voices from outer space and claiming to be possessed. However, it was soon discovered that his lawyer had advised him to adopt this strategy, which ultimately proved futile. Onoprienko was sentenced to life in prison and passed away from a heart attack in 2013.

The Suicide Webster Murderer 

The internet serves as a platform for individuals to connect, engage in discussions, and share aspects of their lives, if they choose to do so. In Japan, however, there is a disturbing phenomenon where individuals who are depressed and no longer wish to live seek out similar individuals online. They form pacts and subsequently meet in person to end their lives together, avoiding the loneliness of dying alone. Tragically, this practice has attracted the attention of a notorious serial killer named Hiroshi Maeue. Maeue preyed on these vulnerable individuals, luring them into meeting him under false pretenses. His victims included young girls, a 14-year-old boy, and a college student, all of whom were bound, restrained, and ultimately murdered. It is believed that Maeue suffered from a paraphilic psychosexual disorder, which compelled him to derive pleasure from witnessing others in pain and distress.
