Man who killed nine people with bomb at Yellowknife's Giant mine seeks parole

ABBOTSFORD, B.C. - A man serving a life sentence for the deaths of nine people in the 1992 Giant gold mine bombing in Yellowknife is seeking day parole for the first time.

Roger Warren was convicted of nine counts of second-degree murder in 1995.

He was eligible for day parole in October 2010 and full parole last October, but didn't apply.

Warren, who is 70, is serving his sentence at a prison in British Columbia.

The Parole Board of Canada's Pacific region office says his day parole hearing will be held this spring, perhaps in June.

Warren confessed to setting a bomb that killed nine miners who had crossed a picket line at the mine owned by Royal Oak Mines.
