SUNDRE, Alta. - Alberta wildlife officers have killed a female grizzly bear who fatally mauled a hunter near Sundre last week southwest of Red Deer.

A government official says officers are now trying to trap the dead bear's three cubs, which are believed to be more than one-year old.

The official said if the cubs cannot be trapped and relocated, they may be killed as well.

Robert Wagner, 48, of Didsbury was reported missing after failing to return from a hunting trip Sept 29.

People concerned about grizzly bears in the area plan to meet with provincial wildlife officials tonight near Cremona.

Alberta bear experts estimate there may be less than 500 grizzlies left in the province.
