British Serial Killers

Dr. Harold Shipman is one of the most prolific serial killers in history. He was convicted of 15 murders, but is believed to have killed nearly 250 of his patients by overdosing them. His victims were mainly elderly people. Despite several clues, including a warning to the police from a funeral home about the doctor's behaviour, Shipman was able to commit his murders undetected for years. It was only after a patient's daughter raised objections to her mother's will that the full extent of Shipman's crimes came to light. His conviction led to major legislative changes in the UK health care system.

Dennis Nilsen was both a serial killer and a necrophile, who killed at least 12 men. Many of them were homeless and homosexual. Dennis Nilsen would keep the bodies of his victims in his apartment for weeks, just for the sake of company. His first victim was a boy of just 14 years old. He was finally arrested when a blockage of the sewage system in his house was caused by some body parts of one of his victims.

Fred West is said to have murdered at least 12 people, some of them together with his wife Rose. The victims were buried in the basement and garden of their home, which became later known as the House of Horrors. The couple tortured and even killed their own daughter. How it is possible that they have could commit their horrible acts for such a long time, even after several warnings to the authorities about the circumstances in the family, remains a question till this day.
