Christopher Whitcomb (on the Idaho murders) | Armchair Expert with Dax Shepard

Christopher Whitcomb, a former FBI agent and Hostage Rescue Team sniper, joins Dax Shepard to discuss his book Broken Plea and his claims about evidential gaps in the University of Idaho student murders case. Whitcomb first recounts his career path into the FBI and major incidents including Ruby Ridge and Waco, describing the pressures of sniper work and how operational decisions and rules of engagement can become the centre of later legal scrutiny.

On the Idaho killings, Whitcomb says he reviewed body-worn camera footage, police files and disclosure material released after the guilty plea by Bryan Kohberger. He argues the prosecution timeline implies a three-and-a-half to five-minute window for four killings across two floors, and questions how that squares with witness accounts and forensic indicators. He highlights what he says are discrepancies between the two bedroom crime scenes and shared areas, including claims that some blood in common spaces appeared “diluted”, while little to no tested blood was recovered from floors between rooms. He also raises staging questions, including his assertion that a blanket was placed over one victim after injuries were inflicted.

Whitcomb further disputes the precision of cell-tower analysis in Moscow and questions how DNA on a knife sheath was handled and described, citing what he says are inventory entries and hearing testimony that complicate public understanding of the match. Whitcomb stresses he is not presenting a wrongful conviction case, but argues the absence of a trial prevented contested evidence from being publicly tested.

• Whitcomb says the state’s case implied a 3.5–5 minute window for the four killings, which he argues is difficult to reconcile with movements and violence described.
• He says bodycam footage shows an early responding officer initially describing the scene as a possible murder-suicide.
• Whitcomb alleges a prosecution expert report described blood in shared areas as “diluted with an unknown substance”, and he disputes the suggested explanation.
• He claims no tested blood was recovered from floors between the two bedroom scenes, despite purported cast-off patterns in shared areas.
• Whitcomb says evidence suggests a blanket was placed over Ethan Chapin after injuries were inflicted, raising staging questions.
• He argues limited cell-tower density meant phone pings could not precisely place Kohberger near the house.
• Whitcomb claims the knife-sheath DNA narrative is complicated by inventory records and hearing testimony about how the DNA information was communicated.
