The Atlantic County prosecutor's office said Wednesday that 42-year-old Heather Barbera of Ventnor was indicted on first-degree murder, robbery and weapon charges.
Barbera was taken into custody in New York City on July 11, a few days after another relative found the bodies of her mother, 67-year-old Michelle Gordon, and her 87-year-old grandmother Elaine Rosen in Ventnor.
Authorities allege that the defendant, who had been living in the home, used a nightstick to beat the victims, who died of blunt force trauma.
Barbera is being held in the Atlantic County jail and is scheduled to appear for a post-indictment arraignment on Friday.
