Leon and Wendy Camp had been married three years.
She and ex-husband Chad Noe were in a custody battle in 1992 over their son.
Leon Camp always has suspected his wife's former in-laws in her disappearance. He said his wife's former mother-in-law, Beverly Noe, picked her up in Oklahoma City on that fateful day.
“They insisted on picking her up for some reason. I guess they didn't want me knowing where they lived. They didn't want me taking Wendy,” he said.
“She was excited about going but I didn't want her going by herself. I didn't trust the people because of the custody battle. They were scary people. I asked my sister to go.”
Beverly Noe in 1992 told investigators she drove Wendy Camp, Cynthia and Kregear from Oklahoma City to Shamrock but let them out at a Walmart in Chandler on the way back.
She claimed Wendy Camp “kept making nasty remarks and asking stupid questions” so she dropped them off in Chandler, an Oklahoma State Bureau of Investigation agent reported.
In interviews with The Oklahoman and The Associated Press, Beverly Noe still claims she dropped the three off in Chandler. Investigators don't believe her account, sources said.
Leon Camp said his wife called him from Shamrock when she left there that day. He said she would have called him or her mother if she had been stranded in Chandler.
He credits God with the discovery of the skeletal remains, but he said it was a shock when his wife's sister called to tell him late one night.
“That really tore me up,” he said. “I was bawling like a baby. My legs got weak. … I fell to the floor.”
The remains had been dumped in a hole that had been dug for a septic tank, the OSBI agent reported in a court affidavit.
Grover Prewitt, 60, of Bristow, admitted that he called a backhoe driver to fill in the septic tank hole at the direction of his mother after the two women and girl went missing, investigators reported.
He said he never looked inside the hole himself “because he was scared of what he would see,” according to the court affidavit.
According to the affidavit, Grover Prewitt also said his mother asked him to sprinkle black pepper over the area. He said he told her that was “awful damn strange” and she said it would deter dog scents.
Grover Prewitt said his mother eventually told him one time that she “took care” of those three people, according to the affidavit.
The three victims may have been shot, sources told The Oklahoman.
Investigators discovered a revolver in the septic tank hole underneath one of the bodies.
The handle of the gun is visible in the dirt in a photo of the grave released by the OSBI.
