Aurora teen told mom ‘you will pay’ before stabbing her 79 times

An 18-year-old from Aurora, Colo., sent her mother an email that said, "You will pay" the day before she stabbed the woman 79 times, an arrest affidavit filed Friday revealed. Isabella Guzman and her mom, 47-year-old Yun-Mi Hoy, often fought, but her stepfather, Ryan Hoy, told authorities that the teen had recently become more "threatening and disrespectful." His worried wife showed him an email from Isabella on Wednesday morning that said, "You will pay," and she later called the police saying that her daughter "had threatened to harm her," Denver's 7NEWS reported.
