Kouri Richins has been found guilty of killing her husband with a fentanyl-laced Moscow Mule cocktail in a plot to start a new life with her handyman lover and get her hands on his $4 million estate.

The mom of three hung her head as she was convicted of five felonies in connection with the death of Eric Richins, 39.

The jury of six men and six women deliberated for just three hours at the Summit County Courthouse in Park City, Utah, before returning their verdict on Monday.

Dressed in a floral patterned shirt and with her hair scraped back in a neat bun, Richins, 35, appeared stoic, but gasped and hung her head as soon as Judge Richard Mrazik read out her conviction on the first count of aggravated murder.

She kept her head bowed as she heard the word ‘guilty’ ring out in the courtroom another four times for counts of aggravated attempted murder, related to a previous murder plot and two counts of insurance fraud and forgery.

Eric’s family and friends, who have filled at least a row in the courtroom every day of the trial, clutched one another for comfort, while his sister Amy silently dabbed tears from her eyes as the verdict was read.

Richins’ mother Lisa Darden, who has stood by her daughter throughout the case, remained stony-faced and pursed her lips.
