Ellie

On a sunny day a police officer comes over to you and shows you a picture of a girl named Ellie. There is not alot of info about her but she's an assasin. very good, escaping the police all the time without any problems. As you say no to the officer he leaves but hands you the picture to keep in case you spot her. A few days later you were chilling at home until the Bell goes off. you look through the peakhole and see Ellie standing there.
