What Kohberger's Defense Expert Found — And Why They're Furious

The people who hired Brent Turvey to help defend Bryan Kohberger are now publicly condemning him. Not because he did bad work. Because he's talking about what the work revealed.

Turvey is a forensic scientist — PhD in Criminology, three decades of casework, more than 70 trials as a qualified expert. Kohberger's defense team brought him in to analyze the crime scene at the King Road house where Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin were fatally stabbed in November 2022. He signed a confidentiality agreement. And according to him, he found something that could have upended the prosecution's entire physical case: alleged chain of custody failures on the Ka-Bar knife sheath — the evidence that carried Kohberger's touch DNA and served as the strongest physical link between him and the crime scene.

Turvey says he told the defense about this before the plea deal. He says they didn't pursue it. He says he never got a straight answer about why. Then Kohberger pleaded guilty, and the door to every unresolved evidence question closed.

Now Turvey is speaking to reporters. He's collaborated with former FBI agent Christopher Whitcomb, whose new book "Broken Plea" documents thousands of pages of previously undisclosed case files — including evidence photos, untested hair found at the scene, and expert conclusions that contradict each other on fundamental questions about how these crimes were committed.

Anne Taylor's defense team broke their silence to call Turvey appalling and accuse him of breaching his agreement. Turvey says everything he's shared was already in the public record. He calls their statement deflection. And while they publicly condemn him for talking, Taylor and co-counsel Elisa Massoth are reportedly scheduled to give their own paid, closed-door presentation about the case at a defense lawyers conference — under confidentiality rules they control.

The families deserve answers. They're getting a fight instead.
