The defense claims DNA on the knife sheath was “planted.”

Prosecutors asked the court to issue a protective order on the genetic genealogy information developed by the FBI using a DNA profile obtained from the snap of the knife sheath found on Maddie Mogen’s bed.

Kohberger faces the possibility of the death penalty if convicted of the murders of Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin last November. The four students were found dead in their off-campus house in Moscow, Idaho.

Kohberger’s defense attorneys wrote in their objection that they want to see how many other potential suspects were overlooked.

They even suggested that Kohberger’s DNA could have been planted:

“The State’s argument asks this Court and Mr. Kohberger to assume – is that the DNA on the sheath was placed there by Mr. Kohberger, and not someone else during an investigation that spans hundreds of members of law enforcement and apparently at least one lab the State refuses to name.”
