When tragedy struck, the entire system answered the call. On the morning after Christmas in 2000, the small city of Wakefield, Massachusetts, faced something no one could have expected: a workplace turned into a scene of mass murder. In just a few short minutes, seven people were killed inside a tech company office by one of their own-a quiet employee named Michael McDermott. The shock didn't end with the tragedy. It marked the start of the largest homicide investigation in state history. Murderous Rage follows the case from the first police radio call to the final court ruling. Told by one of the lead investigators, this book shows how detectives, prosecutors, and forensic experts worked side by side, piecing together evidence, interviewing witnesses, and staying focused through media pressure and public fear. Through snowstorms, crowded courtrooms, and hundreds of interviews, the investigative team pushed forward. What they uncovered wasn't just how the crime happened, but why-and what could have been done to prevent it. This book isn't about heroes or villains. It's about professionals doing their jobs with care, teamwork, and a shared commitment to justice for the victims. It's a powerful look at how real investigations happen, far from the way they're shown on TV.
