Serial killer cases are still shockingly hard to pin down, but the 2025 numbers in this dataset put that difficulty in sharp focus. While the overall count stays grimly consistent, the distribution by location and method shifts in ways that challenge what many people assume about “typical” patterns. Keep reading to see how those 2025 trends compare across categories and what the data suggests we may be missing.
