    After more than three decades, San Francisco prosecutors have charged Ricky Dawson in the 1992 rape and strangulation of Nancy Hernandez, a 45-year-old woman found dead in a Chinatown alley. Dawson, already serving life for a 1996 Denver murder and previously convicted in a Florida killing, has now been linked by DNA to at least four deaths spanning California, Colorado, Florida, and possibly Washington. This episode examines how cold-case DNA technology connected the crimes, the pattern investigators see across state lines, and what the charges mean for a case that sat unsolved for 34 years.

  • 51 Years, a Landfill, and a Pension: How DNA Finally Caught a Killer in Tucson

    51 Years, a Landfill, and a Pension: How DNA Finally Caught a Killer in Tucson
    2026/06/08
    October 1975, the partial remains of a 73-year-old Tucson man named William Reginald Sipfle were found in a landfill near Ryan Airfield, with no identification, no missing person report, and no answers for the family he left behind. Fifty-one years later, forensic genealogy and DNA technology cracked open the cold case and pointed investigators directly at Sipfle’s own stepdaughter, Carol Ann Beall, now 79, who prosecutors allege killed him and collected up to six hundred thousand dollars from his pension in the decades that followed. This episode breaks down how the case went cold, how modern forensic science brought it back, and what this arrest reveals about the long reach of justice and the extraordinary tools now available to investigators working crimes the system once had no way to solve.

  • Predatory Drift —How Serial Killers Change Hunting Grounds and Vanish Into Cold Cases

    Predatory Drift —How Serial Killers Change Hunting Grounds and Vanish Into Cold Cases
    2026/05/18
    Why do some serial offenders suddenly abandon one hunting ground and reappear hundreds of miles away years later? In this deep forensic investigation, we examine the phenomenon of “predatory drift” — the geographic and psychological migration patterns of violent offenders whose anchor points, routines, victimology, and operational zones evolve over decades. Drawing from behavioral profiling, geographic profiling, environmental criminology, and real cold case dynamics, this episode explores how killers adapt, why investigators often miss the pattern, and how modern forensic analysis is reopening cases once thought permanently unsolved.
