David Parker Ray (November 6, 1939 - May 28, 2002) was an American serial killer and torturer of women suspected by police to have murdered as many as 60 people in the city of Truth or Consequences, New Mexico.

Crimes
David Parker Ray tortured and presumably killed his victims in a $100,000 homemade torture chamber he called his "toy box",[1] which was equipped with what he referred to as his "friends": whips, chains, pulleys, straps, clamps, leg spreader bars, and surgical blades and saws.[1] With these tools it's thought that he terrorized Truth or Consequences for several years with the added assistance of multiple accomplices.

“ Ray was thought to be the center of a web of sadism, sex slavery and murder. His accused disciple, drifter Dennis Roy Yancy, confessed to strangling to death Marie Parker, 22, while Ray took photos. Ray's daughter [Glenda Jean "Jesse" Ray] was convicted of kidnapping Kelly Van Cleve although her guilt was in question considering certain inconsistencies, the time frame, lack of evidence and changing stories by the accuser. Cyndy Hendy, Ray's live-in girlfriend, was known to the victims as "mistress". Hendy later told authorities that Ray had killed 14 women." Hendy confessed and supplied testimony against Ray for a lighter sentence, instead of the 14 Felonies, she only got 5 charges." (from Slow Death by Jim Fielder)
”

Inside the torture room, along with numerous sex toys, torture implements, and detailed diagrams (made by Ray himself) showing different methods and techniques for inflicting pain, there was an electronic generating device that was used in torture, as well as a 12-volt motorized breast stretcher. Ray would often have a recorded audio tape of himself be played for his victims whenever they regained consciousness. It has been said that Ray had been recorded as saying he killed at least one person a year for 40 years. However, those statements are considered only speculation by the police, since no evidence has been discovered to support them so far.

Trial and conviction
On March 22, 1999, a living victim, Cynthia Vigil,[2] escaped after being kidnapped and enduring torture in a three-day ordeal. To escape Cynthia waited until Ray went to work and then managed to get the keys to the lock of her chains which Ray's accomplice Cyndy Hendy left in a table nearby while answering a phone call. After getting the keys Cyndy noticed Cynthia's attempt at escaping and fighting ensued. During the struggle Cyndy Hendy broke a lamp on Cynthia Vigil's head, but she still managed to unlock her chains and then proceeded to stab Hendy in the neck with an icepick she found on the floor and escaped. A bloody Cynthia Vigil ran away naked, wearing only an iron slave collar and padlocked chains. After Cynthia's escape and rescue, a wounded Cindy Hendy and David Parker Ray were apprehended by the police.

Ray was sentenced to 224 years in prison after being convicted of numerous offenses involving the abduction and sexual torture of three young women at his Elephant Butte Lake home. His first trial ended in a hung jury in Tierra Amarilla, New Mexico. His trial was then relocated to a small cow town where he had been raised decades before. He was convicted of his crimes against Angie Montaño, and then admitted his crimes against Cynthia Vigil Jaramillo and another young woman, as part of a plea deal for a light sentence for Ray's daughter. He died eight months after sentencing, having served two and a half years.[3] Cindy Hendy, who testified against Ray, received a sentence of 36 years for her role in the crimes.
