Protesters still push for federal inquiry into missing, murdered native women

WINNIPEG - About 200 people gathered in downtown Winnipeg to continue a call for a federal inquiry into missing and murdered aboriginal women.

David Harper, head of a group that represents First Nations in northern Manitoba, says governments have so far rebuffed demands for an inquiry.

He says it's time to find out why hundreds of aboriginal women have disappeared or been killed in recent years.

Harper called on the crowd to pressure politicians and said his group will ask the United Nations to get involved.

Calls for an inquiry have grown since the arrest last month of Shawn Lamb in the deaths of three aboriginal women in Winnipeg.
