She pleaded guilty in May to 3rd-degree murder in the April 2010 slaying of Jose Armando Cazares-Olarte, who prosecutors said was abducted from his Collingdale home, driven to Upper Merion and beaten with a rock.
Hernandez-Cortes told the court that she had been physically and sexually abused. Her attorney said he had hoped for a lesser sentence.
Judge Joseph Smyth said that without the case's other circumstances she could have been sentenced to 20 to 40 years in prison.
