A botched Valentine’s Day plot allegedly involving a poisoned sandwich.

A curious jailhouse letter, journal entries and a ghostwritten children’s book about grief.

A stash of deleted texts, internet searches and cell phone evidence that she believed would never see the light of day.

Now, the final evidence has been shown to jurors. The last witnesses have spoken. And the fate of 35-year-old mom-of-three Kouri Richins will soon be decided.

In a move that took everyone by surprise, Richins’s defense suddenly rested without calling a single witness in her trial for the murder of her husband Eric Richins.

Right up until that moment, her team had indicated plans to summon multiple witnesses to the stand inside Summit County Courthouse in the ski town of Park City, Utah. Five weeks were set aside for the trial, with expectations it would end around March 27.

But it was the state’s final witness, lead investigator Detective Jeff O’Driscoll, who closed out all testimony on Thursday, detailing how the net ultimately closed in on the woman allegedly falsely masquerading as a grieving widow.

Inside the courtroom, where the Daily Mail sat just feet from Richins for several days, it remains a mystery where the jury now stands.

Over 13 days, the panel of six men and six women watched and listened attentively, took notes and leant forward in their seats to closely eye the wealth of evidence during testimony about extramarital affairs, financial woes, family rifts and drug deals.

Richins’s reactions, meanwhile, were easier to read.

Shackled at the defense table each day, the former real estate agent’s face told a story. She raised her eyebrows, pulled faces and stared down witnesses as friends, family and experts testified about her alleged comments, behavior and actions up to and around the time of her husband’s death.

If the constant reminders of her husband’s last moments triggered sadness, she didn’t show it.

There was no flicker of emotion when the fraught 911 call from the night of Eric’s death was played nor when her ex-lover was reduced to tears on the stand as he was faced with their romantic messages and plans for a future life that never was.

Prosecutors allege that Richins murdered the father of her three children by poisoning him with a fentanyl-laced Moscow Mule cocktail on March 4, 2022.

An autopsy found that Eric, a 39-year-old successful stonemason, died from a fentanyl overdose, with more than five times the lethal limit in his system.

At the time of his sudden death, Richins’s finances were ‘imploding,’ her real estate business was in tatters and she owed a staggering $7.5 million in debt to more than 20 payday loan and high-interest lenders.

The mom-of-three was also having an affair with handyman and military veteran Robert Josh Grossmann. In texts before Eric’s death, she spoke of her dream that they could be together. In the days after, of her wish to make him her new husband and their upcoming vacation to a luxury Caribbean resort.

She had allegedly confided in friends about feeling ‘trapped’ in her marriage, with one close friend, Becky Lloyd, testifying that Richins said she felt ‘in many ways it would be better if [Eric] were dead.’

With her husband gone, prosecutors allege Richins believed she could finally start afresh with her lover and also get her hands on a much-needed cash injection from her husband’s $4 million estate.

Richins denies the allegations and has pleaded not guilty.

She is charged with five felonies: aggravated murder, aggravated attempted murder, two counts of insurance fraud and forgery. If convicted, she faces life in prison.

At the heart of the case is the star witness Carmen Lauber, the Richins’s housekeeper who testified that she provided Richins with the fentanyl that killed Eric.

Lauber told the court she sold drugs to Richins four times around the time of Eric’s death.
