In the early morning hours of November 16, 2012, Willoughby Hills Police officers respond to a domestic homicide in progress. The 911 caller is the victim's daughter and, screaming in sheer terror, tells the dispatcher that her foster sister, Sabrina Zunich, keeps stabbing her foster mother with a kitchen knife. Once in custody, the killer teenager shares a dark secret about one of the family members and reveals the real motive behind her vicious murder.
