  • The Drop of Blood - The Nadine Madger Cold Case
    This episode details the decades-long investigation into the 1980 murder of Nadine Madger, a young mother found stabbed to death in her Willoughby, Ohio, home. For years, the case remained cold as police struggled with limited evidence, while Nadine's husband, Mark Madger, faced unjust public suspicion. The narrative highlights the persistence of law enforcement and the revolutionary impact of investigative genetic genealogy in identifying the perpetrator forty years later. By building complex family trees from a foreign blood sample found at the crime scene, researchers eventually linked the DNA to Steven Simcak, a local man who had died in 2018. Additional evidence, including his canary yellow car and a suspicious absence from work on the day of the crime, confirmed his guilt. Though Simcak's death prevented a trial, the breakthrough finally provided closure for Nadine's family and vindicated her husband.

  • The Phoenix Canal Serial Killer Murders
    This source details the investigation into Bryan Patrick Miller, the infamous "Phoenix Canal Killer" responsible for the brutal 1990s murders of Angela Brosso and Melanie Bernas. For over two decades, these horrific cold cases remained unsolved despite DNA evidence linking the two crime scenes near Arizona waterways. A breakthrough occurred when investigative genetic genealogy identified the Miller surname, leading detectives to a suspect already present in their old files. Police eventually used a covert restaurant ruse to collect Miller's DNA from a discarded glass, which successfully matched the decades-old forensic profiles. Though he was also linked by his ex-wife to the disappearance of Brandy Myers, he was ultimately convicted and sentenced to death specifically for the canal murders. This account emphasizes how revolutionary forensic science and persistent detective work can finally bring justice to terrorized communities.

  • Samuel Little: The “Most Prolific” U.S. Serial Killer
    In 2019, the FBI officially designated Samuel Little as the most prolific serial killer in the history of the United States. Though he confessed to 93 murders committed between 1970 and 2005, he evaded detection for decades by targeting vulnerable women whose deaths were often misattributed to natural causes or accidents. Little's nomadic lifestyle and the lack of communication between different police jurisdictions allowed his violent spree to span 19 states. His crimes were eventually uncovered through DNA evidence and hundreds of hours of interviews conducted while he was in prison for other offenses. This overview examines how systemic failures and the social marginalization of his victims permitted such a high body count to go unnoticed for so long. Even after his death in 2020, investigators continue to use his detailed sketches and confessions to provide closure for dozens of cold cases.

    This transcript details the thirty-five-year investigation into the cold-case murders of Shannon Lloyd and Renee Cuevas in Orange County, California. Though the brutal killings occurred years apart in the late 1980s, forensic advancements eventually linked the crimes to a single perpetrator through matching DNA profiles. The breakthrough came decades later when Detective Terra Ramirez and forensic specialists utilized investigative genetic genealogy to identify Reuben Smith as the primary suspect. Although Smith committed suicide in 1998, authorities confirmed his guilt by comparing his archived biological samples to evidence preserved from the original crime scenes. This resolution provided long-awaited closure for the victims' families and highlighted the power of modern technology in solving historic crimes. The account emphasizes the persistence of law enforcement across generations to ensure that violent offenders are ultimately identified.

Despite leaving behind blood and fingerprint evidence, the killer remained unidentified for decades as traditional investigative methods and standard DNA databases failed to produce a match. The case was finally cracked through revolutionary forensic technologies, including DNA phenotyping to determine physical traits and investigative genetic genealogy to build family trees. These advanced methods led detectives to Phillip Lee Wilson, a neighbor living in the same complex at the time of the crime. In 2022, forty years after the attack, Wilson was convicted and sentenced to life in prison without parole.
