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.
