For those asking about BTK. The story was fascinating in that the murders stopped only to return again years later in the same town. He communicated with LE through the newspapers so the public had increased fear reading his about his communications. He would bound then torture and kill. Bind Torture Kill was a name he gave himself. He seemed to want his victim dead. Posing one's body with make up in a church he had attended.
With this desire to kill to get his kicks he is sort of like AS. We have yet to learn what his sexual fantasies are but likely he is into necrophilia. Also he was an elder in his church and family man. AS is also someone you would not expect to commit such a crime. Both crimes have the essence of a dead heart. BTK's confession in court was sterile, unemotional. It makes me think that both of them viewed people as objects. Some of BTK's acquaintances spoke of him as being mean. Going so far as to measure their lawn with a ruler in order to ticket them for city ordinance violations. He also was said to have many dog collars that were thought to be of animals he came across in his job and killed.
Many sexual predators are emulators/copycats. BTK was a copy cat of a prior serial killer. With the recent arrest of Austin Reed Siggs, the tragic cycle continues, imo...:

RDK (short for "Rape, Dismember, Kill") was a notorious serial killer who raped, mutilated, and murdered several women back in the seventies and who was never identified or captured. His crimes were later recreated by a frustrated crime novelist named Humphrey Becker. (SVU: "Scavenger")
In the 1970s, Captain Donald Cragen and Sergeant Max Greevey investigates an unknown man began to rape and murder women. It was never understood why, but by the time he'd finished, five women were dead, their bodies mutilated. A sixth woman, Jeannette Henley, survived; during her rape, he poured gasoline on her skin to torture her, and she managed to grab the bottle and splashed it in his eyes. 25 years later RDK was later re-created by a...
RDK was probably based on the notorious BTK (for "Bind, Torture, Kill"), another anonymous serial killer. However, BTK was later identified as Dennis Rader, who has since been locked away for his crimes.
RDK hung his first victim, then with a knife he cut his second victim's skin which led to her bleeding to death, then he possibly drowned his third victim and decapitated his fourth victim.

Copycat serial killer Eric Olson also copied BTK Rader's M.O. during one of his murders, though he raped that victim while Rader did not do that to any of his victims.
"Go Figure"... The problem is when you have a very intelligent serial killer that emulates/copycats many serial killers prior, changing up their MOs and signatures as did Gary Michael Hilton(GA). FBI VICAP knew that an abnormal amount of women were missing up and down the east coast/Appalacians, yet thought it was many, when it was only one, imo...
