A Crown prosecutor says a young woman who threw a chair off a downtown Toronto high-rise balcony is "lucky she didn't kill someone." The prosecution is seeking a four-to-six-month jail sentence for Marcella Zoia, 20, who pleaded guilty in November to mischief causing danger to life. The chair thrown in February 2019 plummeted 45 storeys onto a busy sidewalk where 20 people had been walking — and next to two busy roadways. Her lawyer says Zoia has shown remorse for her actions.
