A New Jersey woman who beat her 94-year-old grandmother, left her on the floor for two days and then beat her again in what she called "round two" has been sentenced to six years in prison.

Katherine Schubert had pleaded guilty to manslaughter in April for the May 2014 death of Mary Driscoll.

The 39-year-old says after drinking she attacked her grandmother and left her on the floor of their home in Brick without food or water. She says she tried to put Driscoll into pajamas and into bed two days later but then had to "go in for round two and beat her into submission."

Driscoll died at a hospital.

Schubert says she also took sleeping pills and doesn't remember what happened. Schubert apologized before she was sentenced Friday.
