Newly filed court documents say the bodies of two women who were abducted and killed in Oklahoma were reportedly found buried in an ice chest.
Veronica Butler,27, and Jillian Kelley, 39, were killed on a March 30 trip from Kansas to Oklahoma to visit Butler's children.
Five people including Tifany Adams, the paternal grandmother of Butler's children face charges in connection with the killings.
Investigators announced last month that Adams, Tad Cullum, and Cole Twombly and Cora Twombly had been arrested. A fifth suspect, Paul Grice, was later arrested.
The suspects were allegedly members of an anti-government group with a religious affiliation called "God's Misfits," according to their arrest affidavits. They reportedly held weekly meetings at the Twombly's home and another home.
The group allegedly murdered the two women because of a child custody dispute.
Butler was allowed supervised visits with the children each Saturday.
Kelley, the wife of a pastor, was Butler's court-authorized choice to supervise visitations.
Police found their vehicle abandoned near Highway 95 in Texas County and the Oklahoma State Bureau of Investigation said there was evidence to indicate foul play. The evidence reportedly included blood in the vehicle.
The teenage witness told authorities that Cora Twombly said that she and her husband blocked the road to stop Butler and Kelley and divert them to where Adams, her boyfriend Cullum and another person were waiting for them.
The teen reportedly asked why Kelley had to die and was told that "she wasn't innocent either" because she supported Butler," the court papers said.
Search warrants obtained by WFOR-TV stated that, after a two-day excavation in a cow pasture on land leased by Tad Collum, one of the suspects under arrest, the bodies of the two women were found in a chest freezer under poured concrete.
The documents do not disclose who they died.
The landowner says he was shocked when police showed up and found the bodies.
In a motion reportedly filed last November, Adams had opposed adjustments to a supervised visitation arrangement Butler had with the children.
She allegedly claimed that the children had been exposed to sexual abuse while under Butler's care.
Kelley was the wife of a pastor at Hugoton First Christian Church in Kansas. Heath Kelley recently agreed to serve as the new pastor of Willow Christian Church in Nebraska.
