Gustav Müller

Gustav Carl Friedrich Müller (born 1865 in Germany – date of death unknown; in Rotterdam, Netherlands) was a German bigamist, murderer and self-confessed serial killer. When he surrendered himself to the police, Müller confessed to killing his wife and son, as well as his parents and other wives around the world. Only the murders of his wife and son were proven, but taking his insanity into consideration, Müller was acquitted by reason of insanity and sent off to a mental institution, where he presumably died.

Hospitalization in England In March 1893, Müller boarded a ship from India towards England, passing through France on the way. The penniless watchmaker landed at Dover, and at the end of March, he found himself in London. A police constable named Ridgway found the man wandering around Southwark on 30 March and took Müller to the St. George's Workhouse on Mint Street.

There, Müller, speaking in German because he didn't know or understand English, explained to the doctor various fascinating tales, as well as professing that he butchered his parents, wife and several children. Most peculiarly, at times he even claimed that he had killed over 4,000 people, and that the police were hunting him down. His insane claims led the doctor to procure a certificate, with which Müller was sent away to the London County Lunatic Asylum in Banstead, on 15 April 1893.
