5 True Crime Shows That Will Have You Scratching Your Head

The current A&E series follows the 2002 murder of Laci Peterson and her unborn son, Conner, followed by the subsequent trial and conviction of Laci's husband, Scott Peterson, who is currently on death row.

The show examines the evidence against Scott, which was circumstantial, and brings up points like the fact that detection dogs used in the case had failed their tests, and the difficulty of finding an impartial jury due to the case's exposure. The show also interviews investigators on the case who shared the reasons they suspected Scott in the first place.

Another Netflix series, The Keepers centers on the unsolved 1969 murder of Cathy Cesnick, a nun who worked at a Catholic all-girls' school teeming with corruption in the form of priests allegedly sexually abusing the students.

As the series progresses, it appears' Cesnick's murder likely had something to do with her knowledge of the abuse. One former student alleged that a priest at the school took her to see Cesnick's corpse and told her, "This is what happens when you say bad things about people."

Natalee Holloway was 18 when she went missing on a class trip to Aruba over 12 years ago. The Oxygen series follows her father, Dave Holloway, as he attempts to find out what happened to his daughter.

The series appeared to make a break in the case when a sting operation found a man who allegedly confessed to disposing of the teen's remains. The man alleged that Holloway was killed by Joran van der Sloot, the main suspect in the case.

He revealed that van der Sloot later paid him to dig up Holloway's remains and better dispose of them.
