Dr. John Matthias, a criminal psychologist, breaks down the penalty phase of the capital murder trial of Tanner Horner, the man convicted of killing 7-year-old Athena Strand. In this episode, we analyze emotional testimony from family members, claims of generational trauma, autism, and brain abnormalities, and the science presented to explain behavior. But do these factors actually help explain what happened—or are they being used to influence sentencing? This is a deeper look at what the jury is hearing, what it means psychologically, and the question at the center of it all: explanation vs. accountability.
