Netflix is previewing a new true crime documentary, My Father, the BTK Killer. ADVERTISEMENTThe feature stars Kerri Rawson, who learned in 2005 that her father, Dennis Rader, was a serial killer known as BTK, which stood for "Bind, Torture, Kill." It also "weaves together interviews with the investigators who helped uncover BTK's identity and features chilling archival photos and sketches, and interrogation footage of Rader himself." Rader was convicted in 2005 of murdering 10 people over nearly two decades. "It's hard to know who I am if every moment in my life was a lie," she said in the trailer released Monday.
