The movie ‘Clovehitch Killer’ takes inspiration from Dennis Rader, aka the BTK Killer. Dennis was the eldest child in his family with no traumatic past that could cause him to become the cold-blooded killer he became.
However, an alarming indication of his innate cruelty was when he began subjecting stray animals to extreme torture, later killing them.
He tried studying at the Kansas Wesleyan University but later put his education on hold to serve in the US Air Force. After he was discharged, he got married and returned to school, this time earning a degree in the Administration of Justice.
Like the main character in the movie, Rader started murdering within his community and lived a duplicitous life as a community-serving and loving father and a ruthless murderer behind the unassuming facade.
Rader and the Clovehitch killer had a similar modus operandi- stalking their victims with hunter-like precision before binding, torturing, and killing them to achieve sick sexual gratification.
Both also took a 10-year hiatus, before resuming their sick game.
Another similarity is that both the fictional killer and the real BTK killer left clues for police officers as a taunt.
At the end of the movie, Tyler kills his father in an ironic act of justice after he finds out that he was the Clovehitch Killer.
In reality, though, the BTK killer’s arrogance is what does him in, leading the police to find out his identity.
