Less than a month before the murder trial for Kouri Richins is scheduled to begin, her attorneys claim members of the prosecution team have been threatening or harassing witnesses. In a motion filed Sunday, Richins' attorney asked 3rd District Judge Richard Mrazik to require prosecutors and their investigators to turn over all messages with witnesses in the case.

Why it matters

This case highlights concerns about witness intimidation and the potential impact on the fairness of the judicial process. If the allegations are true, it could undermine the credibility of the prosecution's case and raise questions about the integrity of the investigation.

The details

Richins' attorney, Kathryn Nester, said one witness reached out to defense attorneys, saying she was being harassed and asking the defense team if they could do anything 'to protect her from them.' She said the witness made it clear to lead detective Jeff O'Driscoll that she did not want prosecutors to prepare her for her testimony and asked them to send questions in writing. O'Driscoll's response threatened the witness with arrest if she failed to cooperate. Another witness said they were told by the prosecution's lead investigator, Travis Hopper, that their immunity could be at risk if they declined to participate further.

  • Jury selection is scheduled to begin in the case on Feb. 10, 2026.
  • The trial is set to begin on Feb. 23, 2026.

What they’re saying

“You have received a subpoena to appear at the court as a witness. If you fail to do so, the judge will issue a warrant for your arrest. You will then have to sit in a holding cell until you are needed to testify. So make your life easier and answer our calls so we can prep you on what you will be asked. Otherwise, the next time I knock on your door, I'll have a warrant and a catch pole for the dog.”

— Jeff O'Driscoll, Lead Detective (KSL)

“The immunity granted by the prosecution remains conditional upon continued cooperation. Declining to participate further may place that immunity at risk.”

— Travis Hopper, Chief Investigator, Summit County Attorney's Office (KSL)

What’s next

The judge will decide whether to require the prosecution to turn over all communications with witnesses in the case.

The takeaway

This case highlights the importance of protecting witness rights and ensuring the fairness of the judicial process. If the allegations of witness intimidation are true, it could undermine public trust in the criminal justice system.
