"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.
"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."
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.
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.
New affidavit contains revelations about Oklahoma Panhandle murder case that has attracted national attention.
