The Netflix documentary, My Father: The BTK Killer, out Oct. 10, profiles Kerri Rawson, the daughter of the serial killer Dennis Rader , who murdered 10 people in the Wichita, Kansas, area between 1974 and 1991 and was arrested in 2005.

Rader frequently used the term “bind, torture, kill” in letters to local media urging them to investigate him, and he earned the nickname “the BTK killer.” He was finally caught when authorities traced a floppy disk that he sent to a news station in 2005 to a Lutheran church where he held a leadership position. While looking for other family members, investigators obtained Rawson’s DNA from a Pap smear she’d had at a Kansas hospital that matched Rader’s genetic profile.
