Skicross racer Nik Zoricic's parents to dispute death theory

The parents of ski-cross racer Nik Zoricic are holding a news conference this morning in Toronto, where they are expected to outline course design flaws they believe contributed to their son's death during a World Cup competition in Switzerland in March.

Zoricic, 29, suffered head injuries when he crashed into a safety net after landing wide off a jump while nearing the finish line.

Ski officials have described the fall as a freak accident, but his parents are expected to challenge that assertion.

Predrag Zoricic believes the race course where his son died had design flaws, and was an accident waiting to happen.

He is expected to present video and make recommendations to improve the safety of the sport.

Zoricic's parents will speak to the media at the office of their lawyer, Tim Danson.
