A Camden woman who fatally stabbed her identical twin during a drunken street fight is headed to prison.

Amanda Ramirez was sentenced Thursday to six years behind bars after pleading guilty to manslaughter in the death of her sister, Anna.

Ramirez, 27, initially denied stabbing her sister at the Centennial Village Apartments in Camden on June 22. She later admitted to the stabbing but said she had acted in self-defense after her sister came at her with a knife.

Ramirez has said the stabbing occurred after a night of heavy drinking, adding that she can’t remember why she and her sister started fighting.
