On more than one occasion, Eric Richins gets violently ill after having dinner with his wife, Kouri.

Then the pair, who own a successful real estate business, is celebrating a big sale when Kouri Richins fixes her husband a drink. She then goes to take care of the children. Hours later when she goes to bed Eric Richins is dead.

Investigators believe his wife killed him, putting an overdose of fentanyl in his drink. Police also discover that Kouri Richins tried to change the beneficiary to her husband's life insurance.
