Lavoie testified “I was very scared. . . I was trying to defend myself” against 33-year-old Catherine Bergen, of Gloucester, according to The Salem News. Bergen is expected in court next month to face charges of assault and battery on a person 60 or older, assault, disorderly conduct, driving recklessly to endanger and stopping or parking on a state highway.

Witnesses described Bergen as the initial aggressor after stopping abruptly on the highway, the newspaper reported.
