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 in 2019 pointed to Aaron Kosminski, but geneticists challenged the methodology. 137 years later, the case remains open, with more books written about it than any other criminal in history—outpacing #5 in publication volume. Unlike typical unsolved cases, the Ripper's identity is still debated among experts, with over 50 theories proposed annually. The 1888 murders were marked by a lack of forensic tools, making this case a benchmark for historical crime investigation.
