A Vermont woman is due in court to answer a first-degree murder charge in the shooting death of a social worker who police say was killed because the suspect was upset at losing custody of her 9-year-old daughter.

Police say 40-year-old Jody Herring is due to appear in Vermont Superior Court in Barre on Monday afternoon to answer the charge in the death of Lara Sobel.

Police believe that before killing the 48-year-old Sobel, Herring killed three relatives in the adjoining town of Berlin. No charges have been filed yet in that case.

On Sunday, about 300 people remembered Sobel by marching to the parking lot outside the regional office of the Department for Children and Families where Sobel was killed.
