TORONTO - The father of an 18-year-old man who was fatally shot by police one year ago says the questions surrounding his son's death continue to haunt him.

Nabil Yatim released a statement today about the death of his son Sammy, who was shot by police on an empty streetcar in downtown Toronto.

The shooting was captured on surveillance and cellphone videos, and sparked a public outcry that led to marches in the streets of Toronto.

Nine shots could be heard on the videos following police shouts for Sammy Yatim to drop a small fold-up knife he was carrying.

Second-degree murder charges were laid against a police officer.

In his statement, Nabil Yatim says "no parent should have to live through what (he has) endured."
