But as the defense builds its case for life without parole over the death penalty, prosecutors push back—emphasizing accountability, choice, and the undeniable brutality of the crime. With powerful courtroom moments, psychological insight, and critical analysis, this episode walks you through what the jury is now weighing—and what it could mean for justice in Athena’s case.
