Robert Dziekanski Taser Death: Zofia Cisowski Mourns 5 Years Later

VANCOUVER - It's been five years since Polish immigrant Robert Dziekanski died after police zapped him with a Taser at Vancouver International Airport.

His mother, Zofia Cisowski, has gone to place candles and flowers in the exact location where her son died in 2007.

She says she and her son had spent seven years planning his move to Kamloops, B.C., where he was to live with her, but all those dreams were destroyed.

Cisowski is now part of an advocacy group organized by family members and friends of people injured or killed by police.

She says she's heartened to learn of a report showing police have reduced Taser use in B.C. by 87 per cent since her son died.

Dziekanski, who did not speak English, was shocked with a Taser by RCMP who spotted him displaying erratic behaviour after he became lost for hours in the international arrivals area of the airport. (CHNL)
