In this episode, we examine the disturbing case of Daniel Marsh, a 15-year-old who brutally murdered an elderly couple and later described the act as making him feel “happy.”

This episode is not a retelling for shock value. Instead, it explores what many true-crime narratives leave out: the neuroscience, psychology, and developmental factors behind extreme adolescent violence.

Drawing on research in adolescent brain development, psychopathy, trauma, and impulse regulation, we break down:

• How the teenage brain processes violence differently than the adult brain
• The role of empathy deficits, reward circuitry, and emotional regulation
• Whether adolescents can fully understand consequences at this level
• What neuroscience can — and cannot — explain about cases like Daniel Marsh

With a background in public health and behavioral science (graduate training at Johns Hopkins), The Murder Mindset focuses on education, prevention, and accountability, not glorification.
