A Barre woman charged with murdering a Department for Children and Families social worker and three of her own relatives in August 2015 has agreed to a plea deal.

Jody Herring pleaded guilty Thursday in Washington Superior Court to first-degree murder for shooting DCF worker Lara Sobel, WCAX-TV reported.

She also pleaded guilty to second-degree murder charges in the deaths of each of her three relatives. A judge will formally sentence Herring at a later date.

Herring shot Sobel outside a DCF office in downtown Barre in broad daylight, and bystanders apprehended her at the scene. About 12 hours later, authorities discovered the bodies of Julie Falzarano, who was her aunt, and Regina Herring and Rhonda Herring, her cousins, inside a Berlin home.

 Authorities say Herring was upset about losing custody of her 9-year-old daughter. She believed that Sobel and her relatives were responsible.

Herring had been scheduled to go on trial in August. Earlier this year, her attorney abandoned plans to seek a ruling that Herring was incompetent to stand trial.
