Inside the Case Against Kouri Richins: Nate Eaton on the Evidence Behind the Guilty Verdict

ZONE 7 with Sheryl ‘Mac’ McCollum

After weeks of testimony and a defense case that ended without a single witness, the jury in the Kouri Richins trial returned a guilty verdict in the death of Eric Richins.

In this week’s episode of Zone 7, Sheryl McCollum talks with investigative reporter Nate Eaton, who has been in court following the testimony, key witnesses, and the evidence surrounding Eric’s death.

Together, they discuss the prosecution’s theory of motive, the evidence tied to money and deception, the Valentine’s Day attempted-poisoning allegation, and the courtroom testimony that steadily tightened the case.

Sheryl then provides a final trial update after the verdict, focusing on what the defense did not address and what the guilty verdict implies about the case.
