TODAY on The Joe Mangiacotti Show — we're opening the case files!
Joe is joined by retired Watertown Police Detective and forensic investigator Dave MacNeil, president of MacNeil Investigations & Forensic Consulting. Dave spent 36 years with the Watertown Police Department, more than two decades in the Detective Division, and was directly involved in the extraordinary investigation that brought the Boston Marathon bombing manhunt into Watertown — including the Laurel Street and boat crime scenes involving Tamerlan and Dzhokhar Tsarnaev.
Today, two investigators look at some of the biggest cases in the news from the detective's point of view.
🔎 LINDSAY CLANCY: The Plymouth jury is back after twice reporting that it is deadlocked. Could today be the final day? Joe and Dave examine criminal responsibility, behavioral evidence, reconstructing a suspect's state of mind and what a deadlocked jury really tells us.
We'll also look at Dawn Light, the Clancy supporter charged after allegedly recording jurors. Where does public interest in a sensational trial cross the line into potential interference with the justice system?
🔎 KAREN READ — THE FALLOUT: Read was acquitted of the charges involving John O'Keefe's death, but the consequences of the investigation continue. Michael Proctor was fired, other investigators were disciplined or reassigned, lawsuits continue, and questions remain about investigative integrity. Was this corruption, incompetence, tunnel vision — or something else? And how does one compromised investigator damage an entire prosecution?
🔎 TYLER ROBINSON: The man accused of assassinating Charlie Kirk has now pleaded not guilty. Why did it take nearly a year to reach this point? What is his emerging defense? What about the death penalty, forensic evidence, cameras in the courtroom, pretrial publicity and Erika Kirk's highly visible presence?
🔎 THE BOSTON MARATHON BOMBING: Dave takes us inside an investigation he actually lived. What happens when a massive manhunt lands in your town? How do local police, State Police and the FBI secure enormous crime scenes, preserve evidence and coordinate while the entire world is watching?
And we'll examine Tuesday's Massachusetts primary results and what they may tell us about November.
This isn't just true crime. It's about HOW investigators know what they know — evidence versus assumption, good investigations versus bad ones, confirmation bias, crime-scene integrity, witness credibility and reasonable doubt.

Today we're not just asking, “Who did it?”
We're asking the investigator's question:
“What does the evidence actually tell us?”
