DNA Match Solves 17-Year-Old Cold Case Murder

In August 1987, a nineteen-year-old woman named Diana Dieso was discovered brutally murdered and sexually assaulted along the Hudson River. Investigators struggled to identify a suspect for a decade until a cold case detective re-examined the physical evidence and generated a genetic profile that matched a convicted felon named Ray Keller. Law enforcement officials subsequently interviewed a previous victim who noted chilling similarities to her own assault, and a forensic psychologist provided valuable insight into the offender's deep-seated insecurities. Armed with this crucial DNA evidence and psychological strategy, detectives confronted the incarcerated criminal during a prison interview. Ultimately, the pressure prompted a full confession from the perpetrator, leading to his eventual prison sentencing decades after the tragic crime occurred. Content Warning: This podcast contains discussions of homicide, violence, abuse, and other graphic themes related to real-life criminal events.
