Also featuring in the second season of the true-crime series is the "BTK" killer - also known as Dennis Rader.
The murderer was responsible for the death of 10 people between 1974 to 1991, binding, torturing and killing them (which earned him the name "BTK").
He later told the police that his actions were born from a fetish, where we found sexual pleasure in killing and bonding people.
The character appeared in season one of the series, and viewers were able to see the killer in his real-life job of installing security systems.
The teaser trailer for season two hints at a woman discovering one of the BTK killer’s victims behind a rope-sealed door.
With Rader avoiding arrest until 2005, this storyline may be fleshed out over several seasons.
Also rumoured to appear are criminals like, Elmer Wayne Henley, Paul Bateson, The Son of Sam, David Berkowitz, Wayne Williams, William Pearce, JR and William Henry Hance.
Season two of Mindhunter will involve a time jump to the Atlanta child murders of 1979, in what is set to be a chilling a season.
"This person you’re after, he has an overwhelming fantasy life. Fantasies of what he’s done, what he wants to do," serial killer Ed Kemper (played by Cameron Britton) can be heard saying in the teaser.
"His dreams will consume him. The real world won’t even compare."
