Netflix Drops A Few Clues About Mindhunter Season 2

We're a little bit closer to cracking the case of which killers will be featured in the second season of "Mindhunter" on Netflix.

The moody thriller, directed by David Fincher, is based off the experiences of former FBI profiler John Douglas, called Holden Ford in the show and portrayed by Jonathan Groff. The show follows the creation of a unit of the FBI that profiles serial killers to learn how they think and help solve open cases.

At the end of season 1, Holden collapses while talking to serial killer Edmund Kemper. In a still above, we see Holden in a hospital bed. The storyline could reflect a real-life episode from Douglas' life: While he was working to solve the Green River Murders, he was diagnosed with encephalitis, which almost killed him. 

Media got a sneak peek of stills from the show, followed by a look at a trailer for season two, which will be available to fans in coming days. Here's what we know so far ahead of the show's premiere on August 16.

Our favorite wizened investigator and profiler is back on the scene, dispensing tough love (we hope). He also is working on a crazy cypher.

John Douglas previously told Oxygen digital correspondent Stephanie Gomulka the new season would showcase the infamous Atlanta Child Murders. He noted he actually faced backlash for his profile of the possible killer in the 1980s. 

“I said the killer is going to be in his mid-20s and he’s going to be African-American,” Douglas said. “He’s going to be a police buff, which he was, he was arrested for impersonating a police officer. He’s going to have a dog, a police-like dog, which was the power kind of dog back then.” 

He went from being reprimanded by the FBI to later receiving a letter of commendation for his work on the case, Douglas said. 

(Despite police claiming Wayne B. Williams was linked to at least 20 victims, Williams was never charged in connection to the Atlanta Child Murders. He was found guilty for the murders of two adult men and is currently serving a life sentence. Williams has maintained his innocence.)

Several photos provided to media show the investigators working with someone new. Some IMDB stalking leads us to think it's Atlanta Police Commissioner Lee Brown (played by Dohn Norwood). We could be wrong.

We saw glimpses of him last season. Now he's using a Walkman. But will he start using floppy disks?

David Berkowitz, who terrorized New York City during the summer of 1976, gets chatted up.

We think (again, thanks, IMDB) that this is serial killer Montie Rissell (portrayed by Sam Strike).

We think, and the name on the shirt gives a big clue, that this is William Pierce Jr., who murdered the 13-year-old daughter of a South Carolina state senator, among other victims.

Manson ended up getting a different distinctive feature for court: an X carved into his forehead to represent him "x"-ing himself away from the world. He later changed it to a swastika. Many of his followers followed suit during the trial. Photo: Getty Images

Media also got a sneak peek at the trailer, which briefly showed crime scene photos from the LaBianca murders, as well as Damon Herriman portraying Charles Manson (the actual Charles Manson is pictured above). Herriman is having a Helter Skelter year — he also portrays Manson in Quentin Tarantino's "Once Upon a Time in Hollywood."
