The Minot Police Department arrested a Minot woman on Oct. 30 and charged her with killing her boyfriend through poisoning.
Steven Edward Riley Jr, a 51-year-old Minot man, died on Sept. 5, 2023, at a Bismarck hospital. Riley was initially brought to Trinity Hospital but was transferred to a Bismarck hospital where he later died. Autopsy results determined that the cause of death was poisoning.
Police believe that Riley’s girlfriend, 47-year-old, Ina Thea Kenoyer, Minot, had financial motives to murder Riley.
Kenoyer is charged with Class AA Felony Murder and is being held at the Ward County Jail.
“This case was extremely complex,” Investigations Commander Capt. Dale Plessas said. “Thank you to everyone who provided us with information that helped our investigators piece this together.”
The investigation is ongoing.
