In 1967, an ambush on a quiet Tennessee road left Sheriff Buford Pusser wounded and his wife, Pauline, killed.
Decades later, new investigative forces have taken a fresh look at the case. In part one of a three-part investigative series, Sheryl McCollum brings back author and researcher Mike Elam, veteran homicide detective Jason White, eyewitness Dennis Hathcock, and former death investigator Danny Cupples to revisit what actually happened that August evening.
They recount evidence that challenges the official narrative: guns being transferred between vehicles, a frantic officer making threats at a woman’s home, and a teenage witness discovering part of Pauline’s remains near the roadway.
For more background on the Pusser case, listen to Sheryl’s previous Zone 7 episodes:

This week on Pathology with Dr. Priya, a Zone 7 series, Sheryl McCollum and Dr. Priya Banerjee continue their forensic review of the 2011 death of Ellen Greenberg, a young woman found with more than twenty stab wounds in her Philadelphia apartment. Picking up where part one left off, Dr. Priya discusses the two critical stab wounds that penetrated Ellen's brain stem and spinal cord; injuries she believes would have rendered her incapable of any further self-harm. From the anatomy of the cervical spine to the forensic interpretation of bruising, Dr. Priya explains why the medical evidence in this case still challenges the official ruling of suicide, and why the Greenberg family continues to fight for justice.

Despite the severity and location of her injuries, Ellen’s death was ruled a suicide not once but twice. In part one, Dr. Priya walks listeners through the science of sharp-force injuries, defines key forensic terminology, and explains why certain wound patterns, especially those to the back of the head and neck, raise significant questions about how this case was ever closed.

Before a body is ever opened, a medical examiner must consider what dangers might be waiting inside: fentanyl, tuberculosis or even a hidden needle. This week on Pathology with Dr. Priya, a Zone 7 series, Sheryl McCollum and Dr. Priya Banerjee share stories from their recent visit to Lake Tobias Wildlife Park. There, they took part in Wildlife CSI training, a hands-on blend of forensic education and animal encounters, including time with Chester, a baby kangaroo who quickly won everyone over. From there, the conversation shifts to the serious risks medical examiners face every day. From bloodborne pathogens and drug exposure to unstable death scenes and unpredictable infections, Dr. Priya offers a closer look at the hidden hazards behind every autopsy.

In this week's Crime Roundup, Sheryl McCollum and Joshua Schiffer discuss one of the most urgent and misunderstood frontiers in criminal law: who owns your identity in the age of AI? From celebrities digitally resurrected without consent to student-athletes blocked from profiting off their own names, Sheryl and Joshua expose the legal chaos surrounding name, image, and likeness (NIL). They share real cases involving image theft, fraud, and stalking to show just how deep this rabbit hole goes, including how NIL rights intersect with immigration law, gambling, and even organized crime. Whether it’s a deepfake of Robin Williams or a repurposed viral video, the message is clear: your face, your voice, and your story... they’re assets. And they’re up for grabs.

In this episode of Zone 7, Sheryl McCollum welcomes back Georgia Durante, whose remarkable life story took another unbelievable turn. While watching a true crime documentary, Georgia did not expect to see her photograph among evidence connected to convicted serial killer Joseph Naso. Sheryl and Georgia discuss how that moment unfolded, how it ties to the unsolved “Alphabet Killer” cases in Rochester, New York, and the shocking realization that Georgia once worked with a man who would later be convicted of multiple murders. Georgia also reflects on her plan to confront him in prison, and why she believes she might have been “the one who got away.”

In February 2017, teenagers Liberty German and Abigail Williams were murdered while walking in the woods near Delphi, Indiana.
The next day, their bodies were discovered, and investigators revealed that Liberty had recorded a brief video of the suspect ordering the girls to “go down the hill.”
After years of speculation, dead ends, and online conspiracy theories, the 2022 arrest of local resident Richard Allen threw the case into an even deeper firestorm of controversy.
