A North Dakota woman, Ina Thea Kenoyer, 48, has been sentenced to 25 years in prison after pleading guilty to poisoning her boyfriend, 51-year-old Steven Edward Riley Jr., with antifreeze. The incident occurred in Minot last October when Kenoyer allegedly used antifreeze to kill Riley, believing he was going to break up with her after receiving a large inheritance.
Authorities revealed that Kenoyer's motive was based on her belief in Riley's inheritance, which investigators later found to be doubtful. Kenoyer entered a guilty plea in May as part of a deal with prosecutors, leading to her sentencing this week.
