We just finished bingeing "The Keepers" on Netflix. Highly recommended -- if you like crime documentaries.

This one starts with the focus on two murders of young women in Baltimore 1972. One of them is a nun/high school teacher. The murderer or murderers have never been arrested, and according to the police departments involved, the cases are cold and unsolved.

Students of the teacher, nearly 50 years later, start digging into the research and uncover an amazingly tangled cover up that involves horrendous child abuse, and (duh) the Catholic church. Their research starts before the "Spotlight" story came out in Boston.

Gripping story and very well made documentary. Definitely recommended if you haven't seen it.
