OXFORD — A Lewiston woman is facing charges for allegedly pointing a loaded handgun at another motorist during what police call a case of road rage.

Oxford police say the confrontation occurred shortly after 3 p.m. Wednesday on Route 121.

Police tell the Sun Journal that two women pulled their vehicles to the side of the road to “have words,” and Sandra L. Lambert pointed a .38-caliber Ruger pistol at the other driver, whose 5-year-old daughter was in the back seat of her car. Both women called police.

Lambert had a concealed weapons permit.

Police are unclear exactly what touched off the argument, but said it could be a case of tailgating.

The 56-year-old Lambert is charged with criminal threatening with a dangerous weapon. She is free on bail.
