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.
In an unusual move, the OSBI made public a graphic color photo of the victims in the grave. The photo reveals the girl's head had tape on it.
A tip led investigators to question Grover Prewitt about his property March 28. He said his mother had bought five acres from him in 1992 and put a trailer there.
He said his sister, Beverly Noe, had him hire a backhoe driver to dig a hole for a septic tank, according to the court affidavit prepared by an OSBI agent.
The agent reported, “Grover said the hole for the septic tank sat empty for a while but then all of a sudden, after the females went missing, Ida had Grover call the backhoe driver to fill in the hole. … Grover said he thought Ida and Beverly killed the females. … Ida never moved into the trailer and sold the property.”
The agent reported Grover Prewitt showed investigators where the septic tank hole had been dug. The agent reported in a different interview April 2 he grabbed the hand of a district attorney investigator “and told him he really needed to look in that hole he had showed him.”
Twice since the bodies were found April 16, investigators hid a microphone underneath Grover Prewitt's clothes and listened while he met with relatives “in an undercover capacity,” OSBI agent Melissa Gann reported.
Both times he sabotaged the effort to gather evidence, the agent reported.
Beverly Noe was Camp's former mother-in-law. She drove Camp, Kregear and Cynthia to Shamrock to see her son on the day they went missing.
She claims she dropped the three off in Chandler on the way back to Oklahoma City after an argument. Investigators now believe that claim is false.
Beverly Noe told The Oklahoman on April 15, “I dropped them off at the Walmart in Chandler, like I said I did.”
The three victims may have been shot, sources told The Oklahoman.
Camp's sister, Aisha Hashmi, said she was frustrated that only one arrest was made Thursday.
“The people who were last seen with my family members are walking free right now,” she said.
Hashmi, who lives in Texas, supported the release of the grave photo, saying it may lead to more tips. “I think that it will tug a lot of heart strings and people can see what a horrific crime has been committed,” she said.
