On this week's episode of The Trial USA, we bring you up to date on the trial of former real estate agent Kouri Richins. She’s accused of murdering her millionaire husband, Eric Richins, with a fentanyl-laced Moscow Mule, before publishing an illustrated children's book about coping with grief.

In March 2022, 39-year-old Eric Richins was found dead in the bedroom of the home he shared with his wife and their three children. At first, his death appeared sudden but unexplained. Then the autopsy results came back. Eric had five times the lethal dose of fentanyl in his system.

Richins has pleaded not guilty, and her defense team says there is no evidence she poisoned Eric, suggesting he may have obtained drugs himself during a trip to Mexico shortly before his death.

As the trial unfolds, jurors are hearing dramatic testimony about the couple’s finances, their troubled marriage, and the people now at the center of the case.

Daily Mail crime correspondent Rachel Sharp joins us from inside the courtroom in Park City to walk us through what jurors have heard so far - from the key witnesses and explosive testimony to the moments that could shape the jury’s verdict.
