Holmes’s murder castle to the 54 active predators in 2023—proves we’ve been mass-producing and mythologizing our monsters for over a century, with each generation seemingly determined to outdo the last in both brutality and body count.

Unsolved Cases Interpretation
Despite the advances in forensic science and the tireless work of investigators, our modern world of true crime is still, for tens of thousands of victims, a haunted house built on the brutal foundation of cold cases and unanswered questions.
How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
