She Made a Killer Flinch: Inside the Idaho Courtroom Moment That Shook the Internet

In this powerful premiere of KBR: On the Mark, hosts Anita Marks and Nevin Shapiro are joined by Gregory Yankow, a recently retired FBI special agent with 23 years of experience and the former lead investigator on the Nevin Shapiro case. Together, they take a deep dive into the headline-dominating University of Idaho quadruple homicide, the chilling details of the Bryan Kohberger investigation, and the disturbing psychology behind one of the most talked-about suspects in recent true crime history. This episode delivers an unfiltered breakdown of the case, packed with exclusive FBI insight, expert criminal profiling, and critical forensic analysis.

Gregory Yankow reveals insider knowledge of the FBI's investigative strategies, including cell tower forensics, victimology profiling, and theories surrounding Kohberger's stalking behavior toward Kaylee Goncalves and Madison Mogen. The episode explores why Xana Kernodle and Ethan Chapin may have been collateral victims in this brutal crime and dissects the timeline that placed Kohberger near the crime scene for weeks prior to the murders. Greg also explains the impact of unsealed court records, how investigators build airtight cases in high-profile killings, and what’s likely to surface as this true crime case continues to unfold.

The conversation turns raw and emotional as the hosts discuss the powerful victim impact statements during Kohberger’s sentencing—especially the viral courtroom moment from Olivia Goncalves, who confronted her sister’s killer face-to-face. The trio explores narcissism in violent offenders, prison dynamics for high-profile criminals, and how killers like Kohberger use psychological manipulation in and out of court. If you’re a fan of true crime documentaries, FBI case files, or trending criminal justice stories, this is a must-watch episode of KBR: On the Mark—your new go-to source for real crime, real experts, and real talk.
