In 1884-85 eight people were murdered by a serial killer or killers. Out of eight murdered people seven were female and one was male. All the victims were killed at night in sleep. Out of eight five woman were dragged out and killed outdoor.
As most of the murders were carried at night hence it was difficult for the people who survived the attack to identify the killer(s).
The killer(s) were thought to wear Mother Hubbard type dress and they covered their faces making it difficult to identify them.
As mysteriously the murder started the murders soon stopped as police arrested hundreds of suspects.
The case is still unsolved as no one was convicted because of lack of proof.
