January 19, 1958 - Altemio Sanchez
Operating in and around Buffalo, New York for over three decades, Sanchez carried out a sustained pattern of sexual violence and murder that went undetected for much of that span. His ability to avoid identification while continuing to attack — across a period stretching from the mid-1970s into the 2000s — reflects both the investigative challenges of cold-case serial crimes and the geographic consistency of his methods. The eventual break in the case came not through traditional detective work but through familial DNA, marking it as an early example of that technique's utility in identifying long-sought offenders.
