Conversations with a Killer: The Ted Bundy Tapes - Netflix
How does a serial killer think when he's on death row? This four-part documentary series gives viewers a look inside this madman's mind through a selection of audio snippets from more than 100 hours of interviews with the notorious killer. Bundy was convicted of murdering more than 30 women in the 1970s and was executed in 1989, but his legacy lives on. What's even scarier than hearing him talk is knowing how many women exalted him after his conviction (both then and now) because of his supposed good looks and charm.

2. Horror at the Cecil Hotel - Investigation Discovery

Horror at the Cecil Hotel - Investigation Discovery
This infamous Los Angeles hotel has a history of deaths, suicides, and occurrences, some of which can never truly be explained. The hotel was the basis of American Horror Story: Hotel, the anthology series' fifth season. Perhaps the most frightening occurrence was the mysterious death of Elisa Lam, a 21-year-old student who was found naked and dead in the hotel's water tank. While that's scary in and of itself, it's what happened in the elevator before her disappearance that will send you running to turn on all the lights. Surveillance video captured her acting strangely in the elevator and the only thing I can say is you have to see the video for yourself. It will haunt you long after this documentary ends.

3. The Assassination of Gianni Versace - FX

The Assassination of Gianni Versace - FX
There's a reason why Darren Criss won multiple awards for his portrayal of Andrew Cunanan, the man who murdered the famous designer in 1997.

This is one series you'll want to binge, and you'll have no choice because you won't be able to take your eyes off the screen.

Aileen Wuornos is better known as America's first female serial killer who was convicted and eventually executed for killing seven men in Florida in 2002. Although the focus is the family's attempt to get a stay of execution because the court's found her mentally sane when she was obviously insane, it features the last interview with Wuornos and seeing her madness will send chills down your spine.

Still, you'll be haunted by these women's stories and will want a friend to be with you as you watch.

6. In Pursuit with John Walsh - Investigation Discovery
