AURORA, Colo. - Police say an Aurora teen accused of stabbing her mother 79 times spat in her face and sent her a threatening email before the slaying.
Eighteen-year-old Isabella Guzman was being held on suspicion of first-degree murder on Friday in the death of 47-year-old Yun-Mi Hoy.
According to an arrest affidavit, Hoy's husband told police that Isabella attacked his wife in their upstairs bathroom Wednesday night. He said Isabella then walked out past him, staring straight ahead and holding a knife.
Hoy called police to her home earlier that day because of Isabella's behavior. Officers warned Isabella that her mother could throw her out of the home.
The teen's father, Robert Guzman, told Denver's KMGH-TV that he had counseled his daughter at her mother's request hours before the killing.
