The hunts for the "BTK Killer" and the Atlanta child murderer are on in Mindhunter Season 2.
The second season of the David Fincher drama is expected to expand the portfolio of the FBI's Behavioral Science Unit -- led by agents Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany) and Professor Wendy Carr (Anna Torv) -- as they finally get to pick the brains of some of the most notorious serial killers of all time, including Charles Manson and David Berkowitz, aka "Son of Sam." The new episodes will focus heavily on the Atlanta Child Murders from 1979-81, and as these first-look images from the new season show, the trio will also finally begin their long pursuit of Dennis Rader, who managed to elude and taunt police and the media for years before finally being captured in 2005.
It has been long suspected that the ADT serviceman in the series (played by Sonny Valicenti) will be revealed as the notorious strangler, and from these images, it's clear he's (still) up to no good. It looks like the writing is on the wall, quite literally speaking, for that long-lasting cat-and-mouse game to begin for Holden.
