NCIS: The Cases They Can't Forget: Ruthless

In the series premiere, NCIS agents detail the hunt for a serial rapist in Jacksonville, N.C., who appeared to be targeting women with military connections. Five of them were spouses of Marines and Navy personnel attached to Camp Lejeune. NCIS formed a joint task force with the Jacksonville Police Department, who were able to connect the attacks. The rapist left behind few clues, and it wasn't until two victims were attacked on the same night that investigators were able to get their first major leads. With the help of those two victims, the task force was able to apprehend him before he could strike again. The United States Naval Criminal Investigative Service is responsible for investigating felony crimes, preventing terrorism and protecting secrets for the Navy and Marine Corps. The agency operates from more than 140 locations around the world and aboard every aircraft carrier and big-deck amphibious assault ship at sea.
