GUYMON, Okla. (KAKE) - Newly released records say two Kansas women who were kidnapped and killed in Oklahoma were found in a freezer that had been buried. 

The court documents state that during their search for 27-year-old Veronica Butler and 39-year-old Jilian Kelley, investigators tracked pre-paid cellphones used by the suspects, which led them to a pasture in Texas County, Oklahoma. 

The investigators found an area on the property where a hole had been dug and filled.  A search warrant was executed at the property on April 13. The next day, officials uncovered a chest freezer containing the bodies of Butler and Kelley.

On April 14, the Oklahoma State Bureau of Investigation confirmed the two were dead and announced the arrests of four people who allegedly belonged to an anti-government group that called themselves “God's Misfits,” the Associated Press reported. A fifth suspect was later charged.

The Hugoton, Kansas women disappeared March 30 while driving to pick up Butler’s two children for a birthday party. Tifany Adams, 54, who is the children’s grandmother, was in a bitter custody dispute with Butler, who was only allowed supervised visits with the children on Saturdays. Kelley was authorized to supervise the visits, according to affidavits.
