Jack the Ripper

Jack the Ripper murdered at least five women in Whitechapel in 1888 with surgical precision, suggesting medical knowledge, yet was never caught. The case has generated over 100 suspects in academic literature, including a royal physician, but no definitive identification exists. DNA evidence published in 2019 pointed to Aaron Kosminski, a local barber, but other geneticists challenged the study's methodology. The 1888 murders occurred before modern forensic tools existed, which is part of why the case remains a benchmark in the history of criminal investigation.
