BRISTOW — Almost 21 years ago, in a hole dug for a septic tank, the bodies of two Oklahoma City women and a 6-year-old girl were dumped after being killed.
The first arrest in the triple homicide case was made Thursday, two weeks after the skeletal remains were found 8 feet deep at a rural grassy field near Jennings.
Charged with being an accessory to first-degree murder after the fact is the property's former owner, Grover Prewitt Jr., 60, of Bristow.
Prewitt 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 a court affidavit.
Later, he said, his mother, Ida Prewitt, had him sprinkle black pepper over the filled in hole to deter dog scents, according to the court affidavit. He said she eventually told him one time that she “took care” of those three people.
Prosecutors allege he acted illegally by helping his mother, who died in 2011, and other family members avoid prosecution. They allege he helped conceal the bodies in 1992 and actively interfered with the investigation this year.
The victims, Wendy Camp, 23; her daughter, Cynthia Britto; and Camp's sister-in-law, Lisa Renee Kregear, 22, had been missing since May 29, 1992.
Investigators believe they were killed because of a custody dispute over Camp's young son, Jonathon, then 4.
The three victims had traveled to Shamrock on May 29, 1992, to visit the boy, who lived with his father.
The father, Chad Noe, is Ida Prewitt's grandson.
More arrests are possible in the case.
The Oklahoma State Bureau of Investigation confirmed Thursday that agents are working the case as a triple homicide.
“We believe several people are involved in this violent crime,” the OSBI said.
The OSBI is awaiting the results of DNA tests to confirm the victims' identities. The agency reported in a news release, though, that investigators have no doubt about the identities.
Clothes and shoes found in the grave match what the three were wearing at the time of their disappearance, court records show. Investigators during the excavation also found a pink backpack with Cynthia's name written on the inside, as well as a medical card for Camp inside a purse.Advisory: Arrest made in Oklahoma cold case
