In this emotional and disturbing breakdown, Lauren Matthias walks through the defense’s final attempt to explain Tanner’s behavior through trauma, autism spectrum traits, fetal alcohol exposure, and childhood neglect… before the prosecution delivers a devastating rebuttal witness from Tanner’s own past. We unpack the expert testimony, the battle over future dangerousness, the prosecution and defense closing arguments, and the jury’s final decision to sentence Tanner Horner to death. This episode also explores the psychological themes at the center of the case — remorse, manipulation, predatory behavior, and whether understanding someone’s past can ever explain unimaginable violence.
