Esmeralda Villalobos is a 27-year old Colombian cab driver in Los Angeles who is obsessed with death and murder. She is flirtatious, talkative, and affable but disturbingly fascinated with what it's like to have killed a man and will ask her passengers very morbid questions about death, and it's clear she has almost a sensual fetish for death and related morbid topics. She is also fascinated with the meanings of names, and will always tell passengers that her surname means "Village of Wolves."
