Kouri Richins’ defense alleges that the Summit County Sheriff’s Office illegally obtained evidence while investigating the death of Eric Richins.

Defense attorneys Kathy Nester and Wendy Lewis say detectives violated Richins’ constitutional rights and argue that the evidence should be ruled inadmissible during her murder trial.

At the center of the motion are the “Walk the Dog” letter and data from her phone and Apple accounts. Defense attorneys argue that investigators took Kouri’s phone without a proper warrant and failed to inform her of her right to remain silent, her right to request a lawyer, and her right to refuse questioning.

The case began when Eric Richins became violently ill on multiple occasions after having dinner with his wife, Kouri.

The couple, who owned a successful real estate business, was celebrating a big sale when Kouri Richins prepared a drink for her husband. She then went to care for their children. Hours later, when she went to bed, Eric Richins was dead.

Investigators believe his wife killed him by putting a fatal dose of fentanyl in his drink. Police also discovered that Kouri Richins attempted to change the beneficiary of her husband’s life insurance policy.
