Teacher and bride-to-be Ellen Greenberg is found inside a locked apartment stabbed 20 times, including the back of the neck. Her body is discovered by her fiancé after he returns from a workout to find the apartment door locked from the inside. The investigation turns away from the scene and toward the evidence. What do searches of Ellen's computer show? What could convince a medical examiner to change a death ruling, and how does missing work from a prominent pathologist fit in?
