COLUMBUS, Ohio-Bryanna Barozzini, a 20-year-old woman, is set to be sentenced after pleading guilty to involuntary manslaughter in the death of 17-year-old Halia Culbertson. The incident, a fatal stabbing, occurred in a northeast Columbus parking lot last year. Barozzini faces a maximum of three years in prison as part of her plea deal. Her defense argues for probation, claiming she acted in self-defense after being attacked.
