‘BTK: Chasing a Serial Killer’ Preview

Dennis Rader is a serial killer who murdered 10 people in Wichita and Park City, Kansas, between the years of 1974 and 1991. He dubbed himself the “BTK Killer” because of how he would “bind, torture, kill” his victims. During his spree, Rader sent taunting letters to law enforcement officials and local newspapers detailing his crimes.

Now in this new three-hour special, ID delves into Rader’s psyche, “sharing intimate details behind his seemingly normal life.”

The documentary revolves around Kerri Rawson, Rader’s daughter, who had no idea that the man who raised her was a monster in disguise. Through additional interviews with those closest to the case, detailed accounts of the investigation, and further explanation of Radar’s brutal and mocking tactics, this documentary reveals what Dennis Rader worked so hard to conceal, following the twisted path that eventually led to his conviction.

Rader was finally caught in 2005 and charged with 10 counts of first-degree murder. Rader eventually pleaded guilty, showing no remorse and describing the murders in great detail. He was sentenced to 10 consecutive life sentences because Kansas did not have capital punishment at the time of his trial. He is incarcerated at the El Dorado Correctional Facility in Prospect Township, Kansas.

He is let out of his cell for one hour a day, five days a week, to shower and exercise. But in a 2019 interview, his daughter did say he is starting to have health problems. She told the Detroit News that he wrote to her and said he thought he may have suffered a stroke, leaving him with short-term memory loss and possible dementia.

BTK: Chasing a Serial Killer premieres Friday, September 4 at 9 p.m. ET/PT on Investigation Discovery.
