The cause of death of murdered Kansas mothers has been revealed months after they were found dead in a cow pasture

An autopsy report reveals disturbing new details about the cause of death of two Kansas mothers who disappeared on a road trip to Oklahoma to pick up their children earlier this year.

On Wednesday, the Oklahoma coroner's office released a summary of the deaths of 27-year-old Veronica Butler and 39-year-old Jilian Kelly.

The report obtained by KSNW lists the probable cause of death as “multiple sharp force trauma” for Butler and Kelly. The report also states that both women's deaths are considered homicides.

The Oklahoma coroner's office said it will release the full report on Nov. 15.

Court documents explain the cause of death of the murdered Kansas mothers

Butler and Kelley were last seen on March 30 when they went to pick up their children before their car was found abandoned near the Oklahoma-Kansas borderAccording to police, a crime is suspected.

Back in April, the Oklahoma Chief Medical Examiner's Office positively identified the two Texas County individuals who died as Butler and Kelly.

The bodies of both women were found in a freezer in a cow pasture.

Court documents obtained by KSNW indicate that one of the defendants, Paul Grice, allegedly stabbed Butler, while Tad Cullum allegedly killed Kelley. According to the documents, Grice severely injured his hand while killing Butler.

The document alleges that Grice threw the clothes he was wearing when he killed Butler, a stun device and the murder weapon into the grave, KSNW reported. It also states that the DNA recovered from the clothing contained both Grice and Butler's DNA.

Cullum also allegedly threw his clothes into the freezer along with the women's bodies that had Kelley's and his DNA on them. Investigators determined that accessories for the knife were found at Cullum's home.

Tifany Machel Adams, 54, one of the Women arrestedShe is reportedly the grandmother of Butler's children. Court records revealed that Adams was involved in a custody dispute with Butler's children. The children's father is in a rehabilitation facility.

Adams, her boyfriend Cullum and couple Cole and Cora Twombly face two counts for first degree murder, two counts of kidnapping and one count of conspiracy to commit murder in connection with the deaths of Butler and visiting leader Kelley, a 38-year-old preacher's wife who was also a mother.

The document also alleges that the Twomblys served as lookouts on the day of the murder and confided in their 16-year-old daughter, hoping she would provide them with an alibi, KSNW reported. It is alleged that Adams purchased the burner phones, stun devices, yellow thongs found around the freezer and even the pants that Cullum wore and buried with the victims.

Interviews with the Twomblys' daughter and a review of Adams' phone and data from three burner phones led investigators to finding the women's bodies on April 14. The 16-year-old said her parents told her they “don’t have to worry.” [Butler] again” and that the two may have been placed in a well, according to previous court documents.

The group's initial plan was to “throw an anvil through Butler's windshield while driving, making it look like an accident because anvils regularly fall off work vehicles,” Cora allegedly told the 16-year-old.

Previous court documents revealed that Adams searched for “taser pain level” and other terms that shed light on the women's horrific deaths during a custody battle.

The four belonged to a religiously affiliated anti-government group called God's Misfits, Fox News Digital previously reported.

Her motive, according to investigators, was to get custody of Butler's two children. Wrangler Rickman, Adams' son, had custody of the children but was confirmed to be in a rehabilitation facility in Oklahoma when the women disappeared. Butler was allowed to have supervised visitation with her children every Saturday and would be allowed unsupervised visitation during an upcoming hearing, according to court documents.

The state argues that all defendants should face a joint preliminary hearing rather than a separate hearing because they allege all five conspired and participated in the murders of Butler and Kelley.
