OSBI: Grandma admitted responsibility for deaths of two Kansas women in Oklahoma

A grandmother admitted after her arrest that she was responsible for the deaths of two women who went missing in the Oklahoma Panhandle on March 30, the OSBI has reported.

Tifany Adams, her boyfriend and a married couple are accused of kidnapping and killing Veronica Butler and Jilian Kelley. They were arrested Saturday after being charged in Texas County District Court.

They are being held without bond.

A lieutenant with the Oklahoma State Bureau of Investigation completed a new affidavit about the case Tuesday in support of a prosecution request that they remain in jail.

"After her arrest on April 13, 2024, during a custodial interview, Adams made statements to law enforcement indicating she was responsible for the deaths of Butler and Kelley," Lt. Amie Gates wrote.

Adams and Butler were in a "problematic custody battle" over Butler's two children, according to the affidavit.

The children had been staying with Adams, according to court documents from the custody dispute. Butler, 27, had come from Kansas to pick the children up for a birthday party. Kelley, 39, a pastor's wife, was along to supervise her visit.

"At a hearing scheduled for April 17, 2024, Butler would potentially have been granted unsupervised visitation with her children," the OSBI agent wrote in the affidavit. "Adams vehemently opposed this and went to great lengths to plan and purchase items used in Butler and Kelley's murders."

Adams, 54, of Keyes, is charged with two counts of first-degree murder, two counts of kidnapping and one count of conspiracy to commit murder.

Charged with the same counts are her boyfriend, Tad Bert Cullum, 43, of Keyes, and Cole Earl Twombly, 50, and Cora Twombly, 44, of Texhoma.

Four arrested belonged to God's Misfits, an antigovernment group

All four have been identified as belonging to an antigovernment group called God's Misfits. They have been appointed attorneys, who have a policy of not talking to the media.

The pathologist is still working to determine the causes of death. The state's chief medical examiner, Dr. Eric Pfeifer, said Thursday they were not shot.

In the new affidavit, the OSBI confirmed that the bodies were found on property leased by Cullum to graze cattle. The bodies were recovered after an excavation of an area of disturbed dirt.

The OSBI revealed in the affidavit a stun gun was also located at the excavation site. Adams had bought five stun guns in Guymon on March 23.

Adams and Cullum were described in the new affidavit as having "a history of violent interactions, including death threats and intimidation against individuals who disagree with their ideas."

At the time of his arrest, Cullum had a rifle, ammunition, body armor and a go-bag prepared at his residence, according to the affidavit.

"Both Cole, who was openly armed, and Cora confronted law enforcement officials in the State of Texas in an attempt to interfere and intimidate witnesses cooperating with law enforcement," according to the affidavit.
