Defense Rests Without Testimony as Kouri Richins Murder Trial Nears Verdict

After prosecutors spent nearly three weeks calling 42 witnesses to the stand at the Summit County Courthouse in Park City, Kouri Richins' defense team took just minutes to rest its case on Thursday, March 12, presenting no witnesses and waiving the defendant's right to testify.

Richins, a 35-year-old Kamas mother of three, is accused of fatally poisoning her husband Eric Richins in March 2022 by lacing a cocktail with a lethal dose of fentanyl. Prosecutors have argued she killed Eric to collect on a life insurance policy and have presented evidence they say shows she was having an affair. She has pleaded not guilty to all charges.

The prosecution's case wrapped up at 11:30 a.m. when lead detective Jeff O'Driscoll of the Summit County Sheriff's Office finished his testimony, capping a witness list that included housekeeper Carmen Lauber, who testified Richins had asked her for illegal drugs on multiple occasions, and Richins' boyfriend. Prosecutors also presented evidence about a handyman named Hayden Jeffs, who told investigators before his death in a 2024 motorcycle accident that Richins had allegedly asked him for fentanyl. A jail call involving Nick Bonsavage, an associate of Lauber's, in which Bonsavage refers to Lauber making money from fentanyl sales, was also referenced.

Among the more striking pieces of evidence: an investigator testified that three memes were accessed on Richins' phone at 8:29 a.m. on the morning Eric died, including one featuring Donald Trump with the text "I'm really rich," another with a man saying "Idiots, Idiots everywhere," and a third showing a woman wiping her eyes with money. The investigator was careful to note he could not confirm who had sent the images or whether Richins herself had viewed them at that time.

Once the state rested, defense attorney Kathy Nester briefly raised the existence of a man who had allegedly gone to the sheriff's office claiming Eric had reached out to him for fentanyl, arguing that Detective O'Driscoll never interviewed him and never pursued the possibility that Eric died accidentally. After a recess, the defense chose not to pursue that testimony.

The defense then moved for a directed verdict, arguing prosecutors had failed to present sufficient evidence for a reasonable jury to convict Richins on all five charges. Judge Richard Mrazik returned to his chambers to consider the motion and ultimately denied it. After approximately an hour-long recess, defense attorneys announced they would rest without calling any witnesses. Richins formally waived her right to testify, and the defense rested around 2 p.m.

The decision drew immediate reaction inside and outside the courtroom. Legal analyst Skye Lazaro, speaking to the strategic calculus behind it, said: "This is always a strategic decision to be made." Lazaro argued the defense had spent the trial limiting what prosecutors could introduce and pressing witnesses hard on cross-examination. "In those cases similar to this I think the defense in this case did a really phenomenal job crossing examining the state, limiting what the state could bring in, making every argument that they possibly could," Lazaro said. The tradeoff, Lazaro noted, is that calling defense witnesses can open the door to prosecution rebuttal evidence.

Jurors were released until Monday, when closing arguments and jury instructions are scheduled to begin at 8:30 a.m. before deliberations get underway. The case against Richins, who was later credited on a children's book about coping with grief following Eric's death, will now rest entirely with that jury.
