Alberta woman pleads guilty to barging through police barricade during standoff

DRUMHELLER, Alta. - A woman has admitted she barged through a police barricade to try to help her son during an standoff with RCMP in central Alberta.

Mary-Claire Frere pleaded guilty to obstructing and resisting a peace officer when she appeared in Drumheller court on Wednesday.

She was given an absolute discharge because she had no criminal record.

Last June, a man who was fired from a car dealership in Trochu (TROH'-shoo), Alta., allegedly threatened to kill his former co-workers.

Police say there was a five-hour standoff at the man's home when he holed up with a knife and refused to come out.

Chad Frere, who is 38, is to go to trial June 5 on two counts of uttering death threats and one charge of assault.
