Mackenzie Shirilla was only 17 years old on the night she crashed her Camry into the side of a commercial building outside Cleveland. Prosecutors argued at her murder trial that the teen had a toxic relationship with her boyfriend, 20-year-old Dominic Russo, and deliberately drove into the brick wall to end their relationship. Shirilla was handed two concurrent life sentences with the possibility of parole after 15 years at her sentencing hearing Monday. Last week, she was found guilty of four counts each of murder and felonious assault, as well as aggravated vehicular homicide and other crimes.
