In the Eric Richins and Kouri Richins case, Eric's death raised suspicion due to the presence of a lethal amount of substances in his system. Kouri, his wife, was subsequently arrested and charged in connection with his death. The arrest came after a thorough investigation that uncovered evidence suggesting her involvement in providing the fentanyl that led to Eric's demise. The case is ongoing as authorities work to gather more information and build their case against Kouri Richins.
