Attorneys for Bryan Kohberger, who has been accused of killing four University of Idaho students, are asking that his trial be delayed.

The court filing cites that a recent NBC “Dateline” special has caused prejudice towards Kohberger and that they now need additional time to prepare.

The defense also believes that moving forward would infringe on Kohberger’s constitutional rights.

The episode also suggested that some of the information aired was nonpublic.  According to the documents, the material was obtained from sources close to the investigation. 

Kohberger’s attorneys also brought up concerns regarding an upcoming book on the case. They claim in the filing that the book’s promotional blurb implies the information leaked to the Dateline crew was not the only incident.

“A continuance is necessary to fully investigate the leaks and to mitigate the prejudicial effects of such inflammatory pretrial publicity occurring so close to the current trial date,” it stated.

Forensic expert and Jacksonville State University Professor Joseph Scott Morgan told Fox News Digital there’s a risk that the TV episode on Kohberger will taint the jury pool.

“I think the first place you have to look is the tainting of the pool, of the jury pool,” Morgan said. “Progressively, it becomes more and more difficult because people form opinions, they put things out there that are not true, and you still have yet to pick a jury. And it’s not like you’re going to Manhattan. You’re talking about Ada County, Idaho. You have a limited pool of potential jurors there.”
