Cutter, gloves, and a hamburger: The calculated murder of Colleen

Cutter, gloves, and a hamburger: The calculated murder of Colleen Ritzer: The crime of a teenager in Danvers.October 2013. A 14-year-old student enters the school wearing gloves, a change of clothes, and a cutter in his backpack. His teacher, Colleen Ritzer, praises him for his drawings and offers him tutoring. Three hours later, Philip Chism will have a hamburger and watch a movie in the theater while his teacher lies dead in the woods.In this episode, we explore the overwhelming evidence that contradicts the defense of a psychotic break: cameras document every change of clothes, every deliberate trip, every calculated gesture. We analyze how such a brutal crime could be executed inside a school without anyone stopping it, and why the methodical post-crime behavior demolished the arguments of insanity.Victim: Colleen Ritzer Date: October 22, 2013 Location: Danvers High School, Massachusetts Status: Convicted; 40 years + concurrent sentence - Philip arrived at class that morning with surgical gloves, a mask, a change of clothes, and a cutter stored in his locker. - Security cameras recorded 16 wounds inflicted in the women's bathroom and three identical changes of clothes in duration. - After moving the body in a recycling bin to the woods, he bought a hamburger and a movie ticket with stolen cards from the victim. - The defense claimed psychotic hallucinations, but his methodical behavior—gloves, evidence disposal, greetings to friends—suggests prior planning.Colleen Ritzer, Danvers Massachusetts, teenage murder 2013, serial killer psychopathy, forensic, homicide investigation, true crime SpanishIf you want to listen to this podcast without ads and have access to premium episodes, we invite you to try our subscription with a 14-day free trial at obomedia.com.© 2026 OBOMEDIA.
