Answer: Jack the Ripper was an unidentified serial killer that started his spree in the 1880s. He is thought to have killed 5 women, but can't say for sure. The investigation for the police mainly consisted of tracing suspicious people seen at the time of the murders. Scientists said they have identified Jack the Ripper from DNA evidence, but this was recent not back then. The police didn't really have any wins except for the fact that the murders stopped around 1888.
