Her name is Abigail. She is accused of 23 murders, but she actually killed 41 people. Her victims were men and women between 20 and 40 years old. She kills when she has a craving for blood, so the time between two murders is random, between days or months. She kills for 10 years before she gets caught. She uses only knives and she covers herself of the blood of her victims after she kills them. 

She is a smart, pretty, smooth talker, violent, sadistic without any empathy for her victims.
