When a judge declared that Rex Heuermann’s trial would begin after Labor Day “come hell or high water,” the Long Island Serial Killer case entered a decisive new phase.

In this episode of Zone 7, Sheryl McCollum is joined by journalist Laura Ingle for a boots-on-the-ground update of the Long Island Serial Killer investigation. They examine the sweeping defense omnibus motion, the ongoing fight over DNA evidence, and what prosecutors are expected to file ahead of the March 3 and March 17 court dates.

They also analyze the arrest of Andrew Dykes in the 1997 murder of Tanya Jackson, known as “Peaches,” and discuss whether that development introduces meaningful, reasonable doubt for Heuermann’s defense.

From a recovered planning document to burner phones and questions of who knew what, their conversation centers on evidence, legal strategy, and whether this case is headed for trial or moving toward a plea deal.

When 84-year-old Nancy Guthrie disappeared from her home, investigators were quickly faced with blood evidence and ransom claims that did not align with standard abduction patterns.

In this episode of "Zone 7," Sheryl McCollum, retired NYPD homicide detectives Dan Murphy and Tom Smith, and forensic pathologist Dr. Priya Banerjee assess why blood at the scene, a prolonged presence inside the home, and Nancy’s medical vulnerabilities undermine the ransom narrative.

The panel also examines investigative decisions and evidence handling that may shape accountability.

An active investigation into the death of 14-year-old Celeste Rivas Hernandez has left the public with a timeline, a Tesla, and an extensive list of unanswered questions.

In this episode of "Zone 7," Sheryl McCollum is joined by journalist Lauren Conlin to review what has been said publicly about Celeste’s initial classification as a runaway, her connections to older individuals, and why the continued absence of a named person of interest raises concern.

They also turn to the arrest of actor/director Timothy Busfield and discuss what can and cannot be concluded from selective “evidence” releases, how credibility gets weaponized in public, and why child abuse allegations demand careful, methodical evaluation rather than internet verdicts.

The LAPD’s most famous cold case, the Black Dahlia, has haunted headlines for generations, and a renewed wave of speculation now argues she was killed by the same person who later called himself the Zodiac.

In this episode of "Zone 7," Sheryl McCollum is joined by forensic pathologist Dr. Priya Banerjee and forensic psychologist Dr. Joni Johnston to put that theory to the test.

They argue Elizabeth Short’s murder reads as intimate and rage-driven, marked by postmortem mutilation and staging, while the Zodiac attacks appear cold and more mission-oriented, closer to an execution than a personal assault.

They also clarify the difference between modus operandi and psychological signature, explain why signatures do not just “cool off” over decades, and urge civilians and investigators alike to test assumptions, scrutinize claims, and bring in smarter minds when the facts demand it.
