Bryan Kohberger’s Evidence Bag Was Allegedly Filled In Twice

The physical evidence tying Bryan Kohberger to the King Road crime scene came down to one item: a Ka-Bar knife sheath carrying a single source of male DNA matched to Kohberger. It was the prosecution’s anchor. And according to a defense forensic scientist who reviewed the chain of custody documentation, it may have been vulnerable to a challenge that could have kept it out of trial entirely.

Brent Turvey, a criminologist with a Ph.D. and testimony in over seventy trials, alleges the evidence bag was documented retroactively. The bag appears to have been filled in twice, with the earliest visible date and initials of lead detective Brett Payne written over the evidence tape sealing the bag. Turvey told reporters the chain of custody was legally insufficient and that the sheath should have been ruled inadmissible.

Moscow Police Chief Anthony Dahlinger pushed back. He stated the department uses electronic barcodes and numbered stickers rather than handwritten logs and that the process met legal requirements. Idaho State Police released a photo of the evidence bag showing an unbroken seal.

The dispute never reached a courtroom. Kohberger pleaded guilty in July 2025 to four counts of first-degree murder and received four consecutive life sentences with no parole. He waived all appeal rights. The victims — Kaylee Goncalves, twenty-one; Madison Mogen, twenty-one; Xana Kernodle, twenty; and Ethan Chapin, twenty — never received the trial their families expected.

Robin Dreeke and I take your questions on the chain of custody dispute, the unidentified hair the FBI says isn’t Kohberger’s, the families’ lawsuit against WSU, and what Kohberger’s letters from jail reveal about the man behind the plea.
