David Parker Ray the Toy Box Serial Killer, sexually tortured and presumably killed his victims. He used whips, chains, pulleys, straps, clamps, leg spreader bars, surgical blades, and saws.
It is thought that he terrorized many women with these tools for many years, while living in New Mexico.
With the added assistance of multiple accomplices, allegedly including several of the women he was dating.
There was a homemade electrical generator that was used for torture. A mirror was mounted in the ceiling, above the gynecologist-type table upon which he would strap his victims.
Ray would also put his victims in wooden contraptions that bent them over and immobilized. Mean while he had his dogs and sometimes other friends rape them.
He said he also wanted his victims to see everything he was doing to them during the torture sessions. Ray had a recorded audio tape of himself.
He played this for his victims whenever they regained consciousness.
